Colocation

Solution Architecture

Huobi swap API colocation solution is built on AWS infrastructure. Client will connect via AWS “PrivateLink” to access Huobi’s services directly through fast AWS connection without being routed to public networks.

Performance Improvement

The network delay of colocation solution is estimated to be 10ms to 50ms faster than the ordinary connection. This improvement estimated should be used as a guidance only as the actual improvement depends on many factors.

Eligibility

Colocation is only available to higher tier market makers. To check if your account is eligible please talk to your dedicated account manager.

Risk Mechanism

Partial Liquidation

Margin ratio is an indicator to estimate the risk of users’assets. When the margin ratio is less than or equal to 0%, liquidation will be triggered.
It is recommended that you pay close attention to margin ratio changes, so as to avoid your positions from liquidation.
Huobi contracts implement a partial liquidation mechanism, in which the system will lower the corresponding tier of an adjustment factor to avoid your positions from being liquidated at one time.
More detail to see: Partial Liquidation

Insurance Funds and Clawback Mechanism

Insurance funds are designed to cover the losses from forced liquidation.
In a fluctuating market, users’ positions may be liquidated. When the order cannot be filled at the takeover price, resulting in huge losses that are greater than the part insurance funds can undertake, the platform will implement the “clawback” mechanism. Each profitable account in the current period compensates the over loss of liquidation according to its profit ratio.
More detail in here: Partial Liquidation

Tiered Adjustment Factor

The adjustment factor is designed to prevent users from extended margin call loss. Huobi Contracts use a tiered adjustment factor mechanism, which supports up to five tiers based on the position amount.
For contracts with different expirations under the different account modes, they are separately calculated. The larger the use’s net positions, the higher the tier, and the greater the risk.
More detail in here: Tiered Adjustment Factor of USDT-margined Contract

Matching Mechanism

  1. Matching System: Order accepted by the Order System will enter the Matching System. Once orders are matched/filled, the settlement service will be executed and the matching result will be returned to the Order System; otherwise, the unfilled orders will go into the order book for matching.
  2. Price Priority: Higher-priced buy orders have priority over lower-priced buy orders; the reverse is true, lower-priced sell orders have priority over higher-priced sell orders.
  3. Time Priority: Buy orders at the same price are executed according to the time of entry to the Server.
  4. When the highest bid price is the same as the lowest ask price of the order book, this price is what we call transaction price.
  5. When the bid price is higher than the lowest ask price of the order book up to the minute, the lowest ask price will be the transaction price.
  6. When the ask price is lower than the highest bid price of the order book up to the minute, the highest bid price will be the transaction price.

Signature Authentication & Verification

Signature Guide

Considering that API requests may get tampered in the process of transmission, to keep the transmission secure, you have to use your API Key to do Signature Authentication for all private interface except for public interface (used for acuqiring basic information and market data), in this way to verify whether the parameters/ parameter value get tampered or not in the process of transmission

A legitimate request consists of following parts：

Create API Key

You could create API Key at

API Key consists of the following two parts.

Steps for Signature

Normative request for Signature calculation Different contents will get totally different results when use HMAC to calculate Signature, therefore, please normalize the requests before doing Signature calculation. Take the request of inquering order details as an example:

query details of one order

https://api.hbdm.com/linear-swap-api/v1/swap_order?

AccessKeyId=e2xxxxxx-99xxxxxx-84xxxxxx-7xxxx

&SignatureMethod=HmacSHA256

&SignatureVersion=2

&Timestamp=2017-05-11T15:19:30

1. Request methods (GET/POST): add line breaker "\n".

POST\n

2. Text the visit address in lowercase, adding line breake "\n"

api.hbdm.com\n

3. Visit the path of methods, adding line breaker "\n"

/linear-swap-api/v1/swap_order\n

4. Rank the parameter names according to the sequence of ASCII codes, for example, below is the parameters in original sequence and the new sequence:

AccessKeyId=e2xxxxxx-99xxxxxx-84xxxxxx-7xxxx

SignatureMethod=HmacSHA256

SignatureVersion=2

Timestamp=2017-05-11T15%3A19%3A30

5. After ranking

AccessKeyId=e2xxxxxx-99xxxxxx-84xxxxxx-7xxxx

SignatureMethod=HmacSHA256

SignatureVersion=2

Timestamp=2017-05-11T15%3A19%3A30

AccessKeyId=e2xxxxxx-99xxxxxx-84xxxxxx-7xxxx&SignatureMethod=HmacSHA256&SignatureVersion=2&Timestamp=2017-05-11T15%3A19%3A30

7. Form the final character strings that need to do Signature calculation as following:

POST\n

api.hbdm.com\n

/linear-swap-api/v1/swap_order\n

AccessKeyId=e2xxxxxx-99xxxxxx-84xxxxxx-7xxxx&SignatureMethod=HmacSHA256&SignatureVersion=2&Timestamp=2017-05-11T15%3A19%3A30

8. Use the "request character strings" formed in the last step and your Secret Key to create a digital Signature.

4F65x5A2bLyMWVQj3Aqp+B4w+ivaA7n5Oi2SuYtCJ9o=

  1. Take the request character string formed in the last step and API Secret Key as two parameters, encoding them with the Hash Function HmacSHA256 to get corresponding Hash value.

  2. Encoding the Hash value with base-64 code, the result will be the digital Signature of this request.

9. Add the digital Signature into the parameters of request path.

The final request sent to Server via API should be like:

https://api.hbdm.com/linear-swap-api/v1/swap_order?AccessKeyId=e2xxxxxx-99xxxxxx-84xxxxxx-7xxxx&order-id=1234567890&SignatureMethod=HmacSHA256&SignatureVersion=2&Timestamp=2017-05-11T15%3A19%3A30&Signature=4F65x5A2bLyMWVQj3Aqp%2BB4w%2BivaA7n5Oi2SuYtCJ9o%3D

  1. Add all the must authentication parameters into the parameters of request path;

  2. Add the digital Signature encoded with URL code into the path parameters with the parameter name of "Signature".

API Rate Limit Illustration

Future, Coin Margined Swap,Option Swap and USDT Margined Contracts are using separate API rate limits.

Please note that, for both public interface and private interface, there are rate limits, more details are as below:

API Limitation on Order Cancellation Ratio

API Best Practice

1. Query contract history orders interface: /linear-swap-api/v1/swap_hisorders

2. Query contract match results interface: /linear-swap-api/v1/swap_matchresults

3. Query contract financial record interface: /linear-swap-api/v1/swap_financial_record

4. Query contract order detail interface: /linear-swap-api/v1/swap_order_detail

5. WebSocket subscription to Market Depth data:

{

"sub": "market.BTC-USDT.depth.step6",

"id": "id5"

}

{

"sub": "market.BTC-USDT.depth.size_20.high_freq",

"data_type":"incremental",

"id": "id1"

}

6. Place order interface (URL: /linear-swap-api/v1/swap_order) and place a batch of orders interface (URL:/linear-swap-api/v1/swap_batchorder):

7. The best deployment of program server

Code Demo

PS: USDT Margined Contracts api is similar to Coin margined swap api and future api.

Swap API FAQ

Access and Authentication

Q1: Is the API Key for swap and spot the same ?

Yes. The Swap API key and spot API key are same. You can create API using the following link. click here

Q2: Why are APIs disconnected or timeout?

  1. The network connection is unstable if the server locates in China mainland,it is suggested to invoke APIS from a server located in 1c area of AWS Tokyo.

  2. You can use api.btcgateway.pro or api.hbdm.vn to debug for China mainland network.

Q3: Why is the websocket often disconnected?

It seems that most of the abnormal websocket issues (such as disconnect, websocket close )(websocket: close 1006 (abnormal closure))are caused by different network environment. The following measures can effectively reduce websocket issues.

It would be better if the server is located in 1c area of AWS Tokyo with url api.hbdm.vn and implement websocket re-connection mechanism. Both market heartbeat and order heartbeat should response with Pong with different format, following Websocket market heartbeat and account heartbeat requirement.here

Q4: what is the difference between api.hbdm.com and api.hbdm.vn?

The api.hbdm.vn uses AWS's CDN service. it should be more stable and faster for AWS users. The api.hbdm.com uses Cloudflare's CDN service.

Q5: What is the colocation service ? which attention points should we know ?

Actually ,colo corresponds to a vpc node, which directly connects to private network of huobi's future, so it will reduce the latency between the client and the Huobi future server (bypassing the CDN)

huobi future and huobi swap have the same colo, so the domain name connecting the USDT Margined Contracts api and the future api are the same.

Note : Colo needs to use api.hbdm.com for signature(authentication) to avoid getting 403 error: Verification failure.

Q6: Why does signature verification return failure (403: Verification failure) ?

The signature process of USDT Margined Contracts is similar to huobi future and coin margined swap . In addition to the following precautions,please refer to the swap or future demo to verify whether the signature is successful. Please check your own signature code after demo verification is successful. The coin margined swap code demo is here. The future code demo is here. The USDT Margined Contracts code demo is here.

  1. Check if the API key is valid and copied correctly.
  2. Check if the IP is in whitelist
  3. Check if th timestamp is UTC time
  4. Check if parameters are sorted alphabetically
  5. Check if the encoding is UTF-8
  6. Check if the signature has base64 encoding
  7. Any method with parameters for GET requests should be signed
  8. Any method with parameters for POST requests don't need to be signed
  9. Check if whether the signature is URI encoded and Hexadecimal characters must be capitalized, such as ":" should be encoded as "%3A", and the space shoule be encoded as "%20"
  10. The authorization of websocket is similar to the authorization of restful interface.Pls note that the json body of the websocket authorization shouldn't be URL encoded
  11. The host in signature text should be the same as the host in your API request.The proxy may change the request host, you can try without proxy;Some http/websocket library may include port in the host, you can try to append port in signature host, like "api.hbdm.com:443"
  12. The hidden text in API Key and Secret Key may have impact on the signature.

If the reason for signature failure has not been found through the above methods. And you can confirm that by this demo which is specially explaining the signature.

Q7: Is the ratelimit of public market based on IP ? Is the ratelimit of interface with private key based on UID?

Yes. The ratelimit of interface with private key is based on the UID, not the API key. The master and sub accounts are separately ratelimited and don't affect each other.

Q8: Is there any recommendation for third-party framework which integrates Huobi swap?

There is an open source asynchronous quantization framework which integrates Huobi future and Huobi swap: here. If you have any quetsions, please open a ticket in github issues.

Settlement

Q1: What is the USDT Margined Swap funding rate settlement cycle? Which interface can be used to check the status when the fund rate is settled?

We warmly remind you that Huobi USDT Margined Swap is settled every 8 hours, and the settlement will be at the end of each period. For example, 00:00 - 08:00 is a period, and its settlement time would be at 08:00; 08:00 - 16:00 is a period, and its settlement time would be at 16:00; 16:00 - 00:00 (+1 day) is a period, and its settlement time would be at 00:00. All times mentioned above are Singapore Standard time (GMT+8).

（1）Orders can't be placed or cancelled during settlement period, error code "1056" will be returned if users place or cancel orders.

You are recommended to request contract information by this two ways:

It's in settlement time if there is any number of 5, 6, 7, 8 included in the returned status code of contract_status, while it indicates that settlement completed and users could place and cancel orders as usual if the returned status code is 1.

（2）When querying fund or position information during the settlement period, error codes will be returned. Error code and their meaning are as following:

  1. Error code "1077" indicates that "the fund query of current perpetual swap trading pair failed during the settlement";
  2. Error code "1078" indicates that "the fund query of part of perpetual swap trading pairs failed during the settlement";
  3. Error code "1079" indicates that "the position query of current perpetual swap trading pair failed during the settlement";
  4. Error code "1080" indicates that "the position query of part of perpetual swap trading pairs failed during the settlement";

You are recommended to read the status code from the returned message. If the above four types of status code appear, the returned data is not accurate and couldn't be used as reference.

Q2: How to query the system status of the exchange?

There are two common statuses of the exchange systems: settlement/delivery in progress; suspended for maintenance; when the system is in these two kinds of statuses, the system will return the response error code and error information when calling the related API interfaces.

a. How to judge whether the settlement/delivery has been done?

Users can judge from the value “contract_status” returned by the “Get Information of an Order” interface (/linear-swap-api/v1/swap_contract_info);

or Subscribe Contract Info (no authentication): public.$symbol.contract_info

If the return parameter contract_status is 1, it means that the settlement/delivery has been done and the trading has been resumed now.

b. How to judge whether the system is suspended for maintenance or not?

Users can judge from the value “heartbeat” pushed by the “Queried if system interface is available” interface (https://api.hbdm.com/heartbeat/)

or the “Subscribe system status updates” interface ("topic: public.$service.heartbeat");

If the return parameter heartbeat is 1, it means that the system is available now and can be connected normally.

Market and Websocket

Q1: How often are the snapshot orderbook subscription and incremental orderbook subscription pushed?

The snapshot orderbook subscription(market.$contract_code.depth.$type) is checked once every 100MS.If there is an update,it will be pushed. It will be pushed at least 1 second.The incremental orderbook subscription is checked once every 30MS.If there is an update,it will be pushed.If there is no update, it will not be pushed.

Q2: How often is the market trade subscription pushed?

The market trade subscription will be pushed when there is a transaction.

Q3: Are there historical Kline data or historical market trade data?

The historical kline data can be obtained via API interface /market/history/kline with the request params from, to (the time period cannot exceed two years). And the qty of data records cannot be exceeding 2000 in each time.

The historical trade data can be obtained by subscribing the websocket topic: market.$symbol.trade.detail

or can be downloaded from download historical market data

But also, you can download that data using The demo of downloading historical market data

Q4: How to get MACD and other technical indicators on Kline?

The API does not have interfaces to get technical indicators such as MACD. You can refer to TradingView and other websites to calculate them.

Q5: What is the definition of timestamp in the document?

The timestamp in the document refers to the total number of seconds or total milliseconds from Greenwich Mean Time, January 1, 1970, 00:00:00 (Beijing Time, January 1, 1970, 08:00:00) to the present.

Q6: What is the definition of the 150 level and 20 level of MBP?

The Subscription of MBP data: market.$contract_code.depth.$type.150 price level means the current bids and asks splited into 150 level by price.20 price level means the current bids and asks splited into 20 level by price.

Q7: What is the meaning of merged depth when subscribing MBP data?

The subscrpition of MBP data:market.$contract_code.depth.$type：

step16 and step18 are merged by 7 decimal places.bids down,asks up. step17 and step19 are merged by 6 decimal places.bids down,asks up. step1 and step7 are merged by 5 decimal places.bids down,asks up. step2 and step8 are merged by 4 decimal places.bids down,asks up. step3 and step9 are merged by 3 decimal places.bids down,asks up. step4 and step10 are merged by 2 decimal places.bids down,asks up. step5 and step11 are merged by 1 decimal places.bids down,asks up. step12 and step14 are combined by single digit.bids down,asks up. step13 and step15 are combined by tens.bids down,asks up.

(1) Compare the incremental price with the previous full MBP data, and replace the order amount with the same price;

(2) If the price is not in the local MBP data,add the price to the local MBP data;

(3) If a price level is gone, data such as [8100, 0] will be pushed.You have to remove the same price of local MBP data;

(4) For the same websocket connection, the incremental data version is incremented; if the version is not incremented, you need to re-subscribe and re-maintain the local full MBP data;

Q14: What's the difference between "funding_rate" and "realized_rate" in the response of /linear-swap-api/v1/swap_historical_funding_rate interface?

Generally, "funding_rate" is equal to "realized_rate".Only when the payment of funding fee will cause the liquidation of the user's position, the funding fee is under or not charged(And the fee is the actual funding fee:"realized_rate").The current funding rate:"funding_rate" remains unchanged.

Q15: When subscribing the same topic of several contract codes, will several ws be needed?

Since Futures, Coin Margined swaps, USDT Margined Contracts and Options are different contracts with different interface addresses, different ws will be needed.

In Futures, Coin Margined swaps, USDT Margined Contracts and Options thereof, as long as the interface address is the same, one ws is enough.

Q16: Is it available to place/cancel an order via WS??

Currently, it is not supported.

Q17: How to subscribe order status?

a. Successfully trade: “Subscribe Match Order Data (matchOrders.$contract_code)” or “Subscribe Order Data (orders.$contract_code)”

b. Successfully cancel: Subscribe Account Equity Updates Data (accounts.$contract_code)

Q18: What is the difference between the “Subscribe Match Order Data (matchOrders.$contract_code)” and “Subscribe Order Data (orders.$contract_code)”?

The pushed data of these two interfaces are different. Compared to “Subscribe Match Order Data (matchOrders.$contract_code)”, there are more fields for “Subscribe Order Data (orders.$contract_code)”

In general, the match order data (Subscribe Match Order Data “matchOrders.$contract_code”) may be pushed faster than the settled order data (Subscribe Order Data “orders.$contract_code”).

The orders of forced liquidation and netting will not be pushed in “Subscribe Match Order Data (matchOrders.$contract_code)”

Q19: How often is the “Subscribe Kline Data (market.$contract_code.kline.$period)” pushed?

If any transaction is completed, it will push every 500ms. If not, it will push according to the subscribe period

Q20: How to judge whether the push is delayed?

Please first synchronize the time of the server through https://api.hbdm.com/api/v1/timestamp), and the “ts” in the returned data is timestamp (ms) and the corresponding time zone is UTC+8.

The outer layer of each pushed data has a “ts”, which represents the time stamp (ms) when the server pushes the data to the client and the corresponding time zone is UTC+8.

When the data pushed arrive, the procedure will record the local time “ts”. When the local time “ts” is much later than the pushing data “ts”, you can use the following methods to improve the delay:

a. Reduce the data pushed by reducing the number of WS subscriptions.

b. Check the stability and speed of the network between procedure and the servers (please replace api.btcgateway.pro with the domain name used by the program)

curl -o /dev/null -s -w time_namelookup"(s)":%{time_namelookup}"\n"time_connect"(s)":%{time_connect}"\n"time_starttransfer"(s)":%{time_starttransfer}"\n"time_total"(s)":%{time_total}"\n"speed_download"(B/s)":%{speed_download}"\n" api.btcgateway.pro

and you will receive data as below:

time_namelookup(s):0.001378

time_connect(s):0.128641

time_starttransfer(s):0.276588

time_total(s):0.276804

speed_download(B/s):2010.000

If you run the above command multiple times in a row, and the results obtained each time are very different, you can: a. Select an appropriate Huobi domain name, b. Optimize or reselect the network where the program is located.

Order and Trade

Q1: What's the reason for 1004 error code?

We notice that the system is sometimes overloaded when the market suddenly turns to be highly volatile. If the system is busy recently or the following prompts appear:

{“status”: “error”, “err_code”: 1004, “err_msg”: “System busy. Please try again later.”, “ts”:}

please be patient, and do not place or cancel order repeatedly during the process to avoid repeated orders and additional pressure on system performance. In the meanwhile, it is recommended to place and cancel orders through Web and APP.

Q2: The same order ID and match ID can have multiple trades. for example: if a user take a large amount of maker orders, there will be multiple corresponding trades . How to identify these different trades ?

The field ID returned by the information interface /linear-swap-api/v1/swap_order_detail is a globally unique transaction identifier. if a maker order is matched multiple times, a trade will be pushed once there is a transaction matched.

Q3: What is the delay for the round trip of huobi USDT Margined swap?

At present,it normally takes about 30-50ms from placing the order to getting the status of the order.

Q4: Why does the API return connection reset or Max retris or Timeout error?

Most of the network connectivity problems ,(such as Connection reset or network timeout ) are caused by network instability , you can use the server in AWS Tokyo C area with api.hbdm.vn , which can effectively reduce network timeout errors.

Q5: How to check the order status without order_id not returned?

If the order_id couldn't be returned due to network problems, you can query the status of the order by adding the custom order number(client_order_id ).

Q6: What to do if it's diconnected after the websocket subscription of account, order and positions for a while?

When subscribing private accounts, orders and positions, the heartbeat should also be maintained regularly ,which is different from the market heartbeat format . Please refer to the "websocket Heartbeat and Authentication Interface" . if it is disconnected ,please try to reconnect.

Q7: What is the difference between order status 1 and 2 ? what is the status 3 ?

Status 1 is the preparation for submission. status 2 is the sequential submission of internal process, which can be considered that it has been accepted by the system. Status 3 indicated that the order has been already submitted to market.

Q8: Is there an interface to get the total assets in BTC of my account ?

No.

Q9: Why is the order filled after the order is withdrawed successfully by placing API cancellation ?

The success return of order cancellation or placement only represents that the command is excuted successfully and doesn't mean that the order has been cancelled . You can check the order status through the interface /linear-swap-api/v1/swap_order_info.

Q10: Does the order status of 10 mean the order is failed?

Query the order status by /linear-swap-api/v1/swap_order_info.If the status is 10,the order is failed。

Q11: How long does it generally take for an API from withdrawing to cancelling successfully ?

The order cancellation command generally takes several tens of ms. The actual status of order cancellation can be obtained by invoking an interface: /linear-swap-api/v1/swap_order_info

Q12: How to get historical liquidation orders?

To obtain historical liquidation orders, you can access the one of two api interfaces: Get History Orders (/linear-swap-api/v1/swap_hisorders【Isolated】or /linear-swap-api/v1/swap_cross_hisorders【Cross】), Get History Match Results (/linear-swap-api/v1/swap_matchresults【Isolated】or /linear-swap-api/v1/swap_cross_matchresults【Cross】) with the return field order_source (order source) to judge. When order_source returns "risk", it means that this order is a liquidated order.

Q13: Does Huob Futures support holding bi-directional position?

Yes, Huobi Futures supports long and short positions being held at the same time.

Q14: How to ensure the order to be rapidly filled?

At present, Huobi Futures does not support market price when placing an order. To increase the probability of a transaction, users can choose to place an order based on BBO price (opponent), optimal 5 (optimal_5), optimal 10 (optimal_10), optimal 20 (optimal_20), among which the success probability of optimal 20 is the largest, while the slippage always is the largest as well.

It is important to note that the above methods will not guarantee the order to be filled in 100%. The system will obtain the optimal N price at that moment and place the order.

Q15: How can API procedure be connected to the exchange more rapidly?

It’s recommended to use a AWS Tokyo c-zone server and the domain name “api.hbdm.vn” to connect to the system.

Q16: It occurs an “abnormal service” error when transferring assets between spots and derivatives.

a. Check whether the request address is the address of Huobi: api.huobi.pro?

b. Check whether the precision of the coin does not exceed 8 decimal places?

Q17: How to confirm whether the position is opened or closed successfully?

Placing an order successfully through “Place an Order” interface (/linear-swap-api/v1/swap_order) or “Place a batch of orders” interface (/linear-swap-api/v1/swap_batchorder) just means the server has received your order placing instructions rather than you have opened/closed a position successfully.

You can check the order status by filling the returned “order_id” in the “Get Information of an Order” interface (/linear-swap-api/v1/swap_order_info) or the “Order Details Acquisition” interface (/linear-swap-api/v1/swap_order_detail); If the order has been filled, the “status” value in the return parameter will turn out 6 (wholly filled)

It is important to note:

a. For “Get Information of an order” interface (/linear-swap-api/v1/swap_order_info), after the settlement or delivery, the system will delete all the orders in ended status (5: partially filled orders have been cancelled; 6: wholly filled; 7: cancelled);

b. There is a delay in “Order Details Acquisition” interface (/linear-swap-api/v1/swap_order_detail), so it is better to fill in “created_at” (order timestamp) and “order_type” (order type, fill in 1 by default). In this way, it will directly query the database, so the query results will be more timely.

Q18: Why are orders canceled by the system automatically?

The order_price_type which can be chosen are IOC, FOK and Maker (Post Only). When the order book cannot meet with the corresponding conditions, the system will cancel the orders automatically:

Post_only: If the order placed is filled with an existing order on the order book immediately, the order will be cancelled to ensure the user is always a maker.

IOC order: If the order cannot be filled immediately, the unfilled part will be cancelled at once;

FOK order: If the order cannot be filled in its entirety, it will be wholly cancelled. No partial fulfillments are allowed.

Q19: How to query the maximum amount (cont) available to open by using users’ current assets?

At present, we do not have an interface by which users can directly query the maximum amount (cont) available to open by using users’ the current asset.

Q20: Are the “order_id” and “order_id_str” the same?

The “order_id_str” is the string format of “order_id”, whose values are the same.

For the “order_id” with 18 bits, the “JSON.parse” in “nodejs” and “javascript” will be “int” by default, and mistakes will occur when analyzing. Thus, we advise using “order_id_str”.

Q21: How to get the active buying/selling quantity in transaction data?

Users can get the data via “Query The Last Trade of a Contract” (/linear-swap-ex/market/trade) interface or by subscribing "sub": "market.$contract_code.trade.detail", thereinto

Amount refers to the trading volume (cont), which is the sum of the buying/selling volume;

Direction refers to the active trading direction.

Q22: The interval between “from” and “to” is “2000*period” when acquiring KLine data, then why the data obtained is []?

When acquiring the Kline data, the two time points “from” and “to” are contained, therefore it includes 2001 pieces of data. However, this exceeds the maximum limit 2000. Therefore, the system will return [].

Besides, the returned data will be [] as well if the interval between “from” and “to” exceeds 2 years.

Q23: How to get the latest price?

There are two methods to get the latest price:

a. Invoking the “Get KLine Data(/linear-swap-ex/market/history/kline)” interface and filling in any “period”, the “close” of the last data in return data will be the latest price;

b. Invoking the “Query The Last Trade of a Contract(/linear-swap-ex/market/trade)” interface, the returned “price” will be the latest price.

Q24: How to get the latest index price?

There are two methods to get the latest index price:

a. Calling the “Get Contract Index Price Information” interface (/linear-swap-api/v1/swap_index), the returned “index_price” will be the latest index price.

b. Calling the “Subscribe Index Kline Data” websocket (market.$contract_code.index.$period), the “close” of the last Kline data in returned data will be the latest index price.

Q25: Will API upgrade affect the operation of the program?

In general, API upgrade will partly influence the ws disconnection. To avoid this, you can set up a ws-reconnect mechanism in advance; Please subscribe to the upgrade announcements for more details:

Coin-margined futures: https://status-dm.huobigroup.com/

Coin-margined swaps: https://status-swap.huobigroup.com/

USDT-margined Contracts: https://status-linear-swap.huobigroup.com/

Q26: What does mean the “margin_balance” in “Query User’s Account Information” interface (api/v1/contract_account_info)?

”margin_balance” refers to the account equity

  1. margin_balance = margin_static + profit_unreal

  2. margin_balance = Account balance + profit_real + profit_unreal

Note: Account balance = margin_static - profit_real, there is only margin_static in the return data of api interface

Each of the two calculation methods above can get the margin_balance

Q27: Is the “risk_rate” (margin rate) in “Query User’s Account Information” interface (/linear-swap-api/v1/swap_account_info) the same as the margin rate on WEB?

Yes, it is

When the “risk_rate” is less than or equal to 0, the position will be liquidated.

Error Codes

Q1: What is the reason for 1030 error code?

If you encounter errors such as {"status":"error","err_code":1030,"err_msg":"Abnormal service. Please try again later.","ts":1588093883199},indicating that your input request parameter is not correct, please print your request body and complete URL parameters, and please check the corresponding API document interface one by one.The common example is that the volume must be an integer.

Q2: What is the reason for 1048 error code?

If you encounter errors such as {'index': 1, 'err_code': 1048, 'err_msg': 'Insufficient close amount available.'}, indicating that your available position is not enough.You need to query the api /linear-swap-api/v1/swap_position_info to get your available position.

  1. Check whether the amount (cont) of position-closing order exceeds the limit? (When there is limit order for closing a position, the quantity that available to be closed will be occupied; hence we kindly remind you to cancel these orders and try again.)

  2. Check whether direction and offset are wrong as follows:

close long: sell to close a long position (direction: sell; offset: close);

close short: buy to close a short position (direction: buy; offset: close);

Only “direction” need to be uploaded when placing a flash close order (close long: sell; close short: buy).

  1. The pending take-profit and stop-loss (tp/sl) orders and trigger orders will not occupy the quantity of the position.

Q3: What is the reason for 1032 error code?

1032 means that your request exceeds the ratelimit. The coin margined swap, future and USDT margined Contracts limit the rate separately. Please check the ratelimit in the api ratelimit instructions, and you can print the current ratelimit in the header of the API response to check whether the ratelimit is exceeded. It is recommended to increase the request interval delay to avoid exceeding the ratelimit.

The usage of and the difference between cross margin mode and isolated margin mode

  1. Under the cross margin mode, all swaps share the USDT in the cross margin account as the margin, which indicates that all positions under the cross margin mode share the same account equity, and their PnL, occupied margin and margin ratio are calculated jointly. Under the isolated margin mode, the account equity for each swaps are calculated separately, and the position margin and PnL of each swaps will not affect each other.

  2. The cross margin mode and the isolated margin mode use different margin accounts, and the assets are independent of each other. Users can trade, or hold positions under the two modes at the same time. For example, in BTC/USDT swaps trading, the margin account for cross margin trading is USDT, while the margin account for isolated margin trading is BTC-USDT.

  3. API users can use the support_margin_mode field (margin mode supported by the contract) of the API interface [Query Swap Info: linear-swap-api/v1/swap_contract_info] to check which mode (cross/isolated) the contract supports.

  4. The API interface is divided into three modes, [Cross], [Isolated] and [General]. These three modes are marked on the API interface name and the interface list. [Cross] indicates that the API interface only supports cross margin mode. [Isolated] indicates that the API interface only supports isolated margin mode, and [General] indicates that the API interface supports both two modes, indicating that it can be called by both the cross margin mode and isolated margin mode.

How to solve problems more effectively?

When you report an API error, you need to attach your request URL, the original complete body of the request and the complete request URL parameters, and the original complete log of the server's response. If it is a websocket subscription, you need to provide the address of the subscription, the topic of the subscription, and the original complete log pushed by the server.

If it is an order-related issue, use the API order query interface /linear-swap-api/v1/swap_order_info to keep the complete log returned and provide your UID and order number.

direction string true Transaction direction
offset string false(more see remarks) "open", "close", "both"
lever_rate int true Leverage rate [ if“Open”is multiple orders in 10 rate, there will be not multiple orders in 20 rate; high leverage has a high risk factor, so please use it with caution.
order_price_type string true "limit”: Limit Order "opponent":BBO "post_only": Post-Only Order, No order limit but position limit for post-only orders.,optimal_5： Optimal , optimal_10： Optimal 10, optimal_20：Optimal 20，ioc: IOC Order,fok：FOK Order, "opponent_ioc"：IOC order using the BBO price，"optimal_5_ioc"：optimal_5 IOC，"optimal_10_ioc"：optimal_10 IOC，"optimal_20_ioc"：optimal_20 IOC, "opponent_fok"：FOK order using the BBO price，"optimal_5_fok"：optimal_5 FOK，"optimal_10_fok"：optimal_10 FOK，"optimal_20_fok"：optimal_20 FOK
tp_trigger_price decimal false Trigger price of take-profit order
tp_order_price decimal false Order price of take-profit order（The order price is not required to fill in for Optimal N)
tp_order_price_type string false Order type of take-profit order default is limit; limit，optimal_5，optimal_10，optimal_20
sl_trigger_price decimal false Trigger price of stop-loss order
sl_order_price decimal false Order price of stop-loss order（The order price is not required to fill in for Optimal N）
sl_order_price_type string false Order type of stop-loss order default is limit; limit，optimal_5，optimal_10，optimal_20

Note ：

"limit"，"post_only"，"ioc" and "fok" the four order price type need price value and the other don't need.

Post-Only orders are limit orders that will never take liquidity (also called maker-only order). There are order limit and position for post-only orders which the upper limit is 5,000,000 for open/close orders.

If you’re holding a position currently, the leverage you choose when placing an order should be the same as the leverage of your current positions, otherwise, the order will fail to be placed. If you need a new leverage to place an order, you should switch the leverage of current positions first by using the Switch Leverage interface.

Only open orders can support setting take profit and stop loss.

The take profit trigger price is a required field for setting a take profit order, and the stop loss trigger price is a required field for setting a stop loss order; if the trigger price field is not filled in, the corresponding take profit order or stop loss order will not be set.

Description of post_only: assure that the maker order remains as maker order, it will not be filled immediately with the use of post_only, for the match system will automatically check whether the price of the maker order is higher/lower than the opponent first price, i.e. higher than bid price 1 or lower than the ask price 1. If yes, the maker order will placed on the orderbook, if not, the maker order will be cancelled.

offset, in hedge mode it is a required field, and in one-way mode it is optional paramater which's value must be both when filled.

open long: direction - buy、offset - open

close long: direction -sell、offset - close

open short: direction -sell、offset - open

close short: direction -buy、offset - close

No need to transfer BBO order price(ask 1 and bid 1) parameter, optimal_5: top 5 optimal BBO price, optimal_10：top 10 optimal BBO price, optimal_20：top 20 optimal BBO price (No need to transfer price data) ，limit": limit order, "post_only": maker order only (price data transfer is needed),IOC :Immediate-Or-Cancel Order,FOK:Fill-Or-Kill Order.

Note

The return order_id is 18 bits, it will make mistake when nodejs and JavaScript analysed 18 bits. Because the Json.parse in nodejs and JavaScript is int by default. so the number over 18 bits need be parsed by json-bigint package.

sl_order_price_type string false Order type of stop-loss order default is limit; limit，optimal_5，optimal_10，optimal_20

Note

"limit"，"post_only"，"ioc" and "fok" the four order price type need price value and the other don't need.

Post-Only orders are limit orders that will never take liquidity (also called maker-only order). There are order limit and position for post-only orders which the upper limit is 5,000,000 for open/close orders.

If you’re holding a position currently, the leverage you choose when placing an order should be the same as the leverage of your current positions, otherwise, the order will fail to be placed. If you need a new leverage to place an order, you should switch the leverage of current positions first by using the Switch Leverage interface.

Only open orders can support setting take profit and stop loss.

The take profit trigger price is a required field for setting a take profit order, and the stop loss trigger price is a required field for setting a stop loss order; if the trigger price field is not filled in, the corresponding take profit order or stop loss order will not be set.

Description of post_only: assure that the maker order remains as maker order, it will not be filled immediately with the use of post_only, for the match system will automatically check whether the price of the maker order is higher/lower than the opponent first price, i.e. higher than bid price 1 or lower than the ask price 1. If yes, the maker order will placed on the orderbook, if not, the maker order will be cancelled.

offset, in hedge mode it is a required field, and in one-way mode it is optional paramater which's value must be both when filled.

open long: direction - buy、offset - open

close long: direction -sell、offset - close

open short: direction -sell、offset - open

close short: direction -buy、offset - close
