API key Creation

Please refer to my api page regarding API Key creation.

Generating an API key

Create an API key on the website before signing any requests. After creating an API key, keep the following information safe:

• API key
• Secret key
• Passphrase

The system returns randomly-generated API keys and SecretKeys. You will need to provide the Passphrase to access the API. We store the salted hash of your Passphrase for authentication. We cannot recover the Passphrase if you have lost it. You will need to create a new set of API key.

API key permissions

There are three permissions below that can be associated with an API key. One or more permission can be assigned to any key.

• Read : Can request and view account info such as bills and order history which need read permission
• Trade : Can place and cancel orders, funding transfer, make settings which need write permission
• Withdraw : Can make withdrawals

API key security

• Each API key can bind up to 20 IP addresses, which support IPv4/IPv6 and network segment formats.
  

• Only when the user calls an API that requires API key authentication will it be considered as the API key is used.
• Calling an API that does not require API key authentication will not be considered used even if API key information is passed in.
• For websocket, only operation of logging in will be considered to have used the API key. Any operation though the connection after logging in (such as subscribing/placing an order) will not be considered to have used the API key. Please pay attention.

Users can get the usage records of the API key with trade or withdraw permissions but unlinked to any IP address though Security Center.

REST Authentication

Making Requests

All private REST requests must contain the following headers:

• OK-ACCESS-KEY The API key as a String.

• OK-ACCESS-SIGN The Base64-encoded signature (see Signing Messages subsection for details).

• OK-ACCESS-TIMESTAMP Request timestamp in ISO 8601 UTC format with millisecond precision, e.g. 2020-12-08T09:08:57.715Z. The server rejects requests where this differs from server time by more than 30 seconds (error 50102). Always use UTC — local timezone offset is the most common cause of error 50102. Synchronise with GET /api/v5/public/time before placing orders.

• OK-ACCESS-PASSPHRASE The passphrase you specified when creating the API key.

Request bodies should have content type application/json and be in valid JSON format.

Signature

Signing Messages

The OK-ACCESS-SIGN header is generated as follows:

• Create a pre-hash string of timestamp + method + requestPath + body (where + represents String concatenation).
• Prepare the SecretKey.
• Sign the pre-hash string with the SecretKey using the HMAC SHA256.
• Encode the signature in the Base64 format.

Example: sign=CryptoJS.enc.Base64.stringify(CryptoJS.HmacSHA256(timestamp + 'GET' + '/api/v5/account/balance?ccy=BTC', SecretKey))

The timestamp value is the same as the OK-ACCESS-TIMESTAMP header with millisecond ISO format, e.g. 2020-12-08T09:08:57.715Z.

The request method should be in UPPERCASE: e.g. GET and POST.

The requestPath is the path of requesting an endpoint.

Example: /api/v5/account/balance

The body refers to the String of the request body. It can be omitted if there is no request body (frequently the case for GET requests).

Example: {"instId":"BTC-USDT","lever":"5","mgnMode":"isolated"}

The SecretKey is generated when you create an API key.

Example: 22582BD0CFF14C41EDBF1AB98506286D

WebSocket

Overview

WebSocket is a new HTML5 protocol that achieves full-duplex data transmission between the client and server, allowing data to be transferred effectively in both directions. A connection between the client and server can be established with just one handshake. The server will then be able to push data to the client according to preset rules. Its advantages include:

• The WebSocket request header size for data transmission between client and server is only 2 bytes.
• Either the client or server can initiate data transmission.
• There's no need to repeatedly create and delete TCP connections, saving resources on bandwidth and server.

Connect

Connection limit: 3 requests per second (based on IP)

When subscribing to a public channel, use the address of the public service. When subscribing to a private channel, use the address of the private service

Request limit:

The total number of 'subscribe'/'unsubscribe'/'login' requests per connection is limited to 480 times per hour.

Connection count limit

The limit will be set at 30 WebSocket connections per specific WebSocket channel per sub-account. Each WebSocket connection is identified by the unique connId.

The WebSocket channels subject to this limitation are as follows:

1. Orders channel
2. Account channel
3. Positions channel
4. Balance and positions channel
5. Position risk warning channel
6. Account greeks channel

If users subscribe to the same channel through the same WebSocket connection through multiple arguments, for example, by using {"channel": "orders", "instType": "ANY"} and {"channel": "orders", "instType": "SWAP"}, it will be counted once only. If users subscribe to the listed channels (such as orders and accounts) using either the same or different connections, it will not affect the counting, as these are considered as two different channels. The system calculates the number of WebSocket connections per channel.

The platform will send the number of active connections to clients through the channel-conn-count event message to new channel subscriptions.

Connection count update

{
    "event":"channel-conn-count",
    "channel":"orders",
    "connCount": "2",
    "connId":"abcd1234"
}

When the limit is breached, generally the latest connection that sends the subscription request will be rejected. Client will receive the usual subscription acknowledgement followed by the channel-conn-count-error from the connection that the subscription has been terminated. In exceptional circumstances the platform may unsubscribe existing connections.

Connection limit error

{
    "event": "channel-conn-count-error",
    "channel": "orders",
    "connCount": "30",
    "connId":"a4d3ae55"
}

Order operations through WebSocket, including place, amend and cancel orders, are not impacted through this change.

Login

Request Example

{
  "op": "login",
  "args": [
    {
      "apiKey": "******",
      "passphrase": "******",
      "timestamp": "1538054050",
      "sign": "7L+zFQ+CEgGu5rzCj4+BdV2/uUHGqddA9pI6ztsRRPs="
    }
  ]
}

Request Parameters

Successful Response Example

{
  "event": "login",
  "code": "0",
  "msg": "",
  "connId": "a4d3ae55"
}

Failure Response Example

{
  "event": "error",
  "code": "60009",
  "msg": "Login failed.",
  "connId": "a4d3ae55"
}

Response parameters

apiKey: Unique identification for invoking API. Requires user to apply one manually.

passphrase: API Key password

timestamp: the Unix Epoch time, the unit is seconds, e.g. 1704876947

sign: signature string, the signature algorithm is as follows:

First concatenate timestamp, method, requestPath, strings, then use HMAC SHA256 method to encrypt the concatenated string with SecretKey, and then perform Base64 encoding.

secretKey: The security key generated when the user applies for API key, e.g. 22582BD0CFF14C41EDBF1AB98506286D

Example of timestamp: const timestamp = '' + Date.now() / 1,000

Among sign example: sign=CryptoJS.enc.Base64.stringify(CryptoJS.HmacSHA256(timestamp +'GET'+'/users/self/verify', secretKey))

method: always 'GET'.

requestPath : always '/users/self/verify'

Subscribe

Subscription Instructions

Request format description

{
  "id": "1512",
  "op": "subscribe",

General Info

The rules for placing orders at the exchange level are as follows:

• The maximum number of pending orders (including post only orders, limit orders and taker orders that are being processed): 4,000

• The maximum number of pending orders per trading symbol is 500, the limit of 500 pending orders applies to the following order types:

  • Limit
  • Market
  • Post only
  • Fill or Kill (FOK)
  • Immediate or Cancel (IOC)
  • Market order with Immediate-or-Cancel order (optimal limit IOC)
  • Take Profit / Stop Loss (TP/SL)
  • Limit and market orders triggered under the order types below:
    • Take Profit / Stop Loss (TP/SL)
    • Trigger
    • Trailing stop
    • Arbitrage
    • Iceberg
    • TWAP
    • Recurring buy

• The maximum number of pending spread orders: 500 across all spreads

• The maximum number of pending algo orders:

  • TP/SL order: 100 per instrument
  • Trigger order: 500
  • Trailing order: 50
  • Iceberg order: 100
  • TWAP order: 20

• The maximum number of grid trading

  • Spot grid: 100
  • Contract grid: 100

The rules for trading are as follows:

• When the number of maker orders matched with a taker order exceeds the maximum number limit of 1000, the taker order will be canceled.
  • The limit orders will only be executed with a portion corresponding to 1000 maker orders and the remainder will be canceled.
  • Fill or Kill (FOK) orders will be canceled directly.

The rules for the returning data are as follows:

• code and msg represent the request result or error reason when the return data has code, and has not sCode;

• It is sCode and sMsg that represent the request result or error reason when the return data has sCode rather than code and msg.

instFamily and uly parameter explanation:

• The following explanation is based on the BTC contract, other contracts are similar.
• uly is the index, like "BTC-USD", and there is a one-to-many relationship with the settlement and margin currency (settleCcy).
• instFamily is the trading instrument family, like BTC-USD_UM, and there is a one-to-one relationship with the settlement and margin currency (settleCcy).
• The following table shows the corresponding relationship of uly, instFamily, settleCcy and instId.

Note:
1. USDⓈ represents USD and multiple USD stable coins, like USDC, USDG.
2. The settlement and margin currency refers to the settleCcy field returned by the Get instruments endpoint.

Transaction Timeouts

Orders may not be processed in time due to network delay or busy OKX servers. You can configure the expiry time of the request using expTime if you want the order request to be discarded after a specific time.

If expTime is specified in the requests for Place (multiple) orders or Amend (multiple) orders, the request will not be processed if the current system time of the server is after the expTime.

REST API

Set the following parameters in the request header

The following endpoints are supported:

• Place order

        "ordType": "market",
        "sz": "100"
    }]
}

Rate Limits

Our REST and WebSocket APIs use rate limits to protect our APIs against malicious usage so our trading platform can operate reliably and fairly.
When a request is rejected by our system due to rate limits, the system returns error code 50011 (Rate limit reached. Please refer to API documentation and throttle requests accordingly).
The rate limit is different for each endpoint. You can find the limit for each endpoint from the endpoint details. Rate limit definitions are detailed below:

• WebSocket login and subscription rate limits are based on connection.

• Public unauthenticated REST rate limits are based on IP address.

• Private REST rate limits are based on User ID (sub-accounts have individual User IDs).

• WebSocket order management rate limits are based on User ID (sub-accounts have individual User IDs).

Trading-related APIs

For Trading-related APIs (place order, cancel order, and amend order) the following conditions apply:

• Rate limits are shared across the REST and WebSocket channels.

• Rate limits for placing orders, amending orders, and cancelling orders are independent from each other.

• Rate limits are defined on the Instrument ID level (except Options)

• Rate limits for Options are defined based on the Instrument Family level. Refer to the Get instruments endpoint to view Instrument Family information.

• Rate limits for a multiple order endpoint and a single order endpoint are also independent, with the exception being when there is only one order sent to a multiple order endpoint, the order will be counted as a single order and adopt the single order rate limit.

Sub-account rate limit

At the sub-account level, we allow a maximum of 1000 order requests per 2 seconds. Only new order requests and amendment order requests will be counted towards this limit. The limit encompasses all requests from the endpoints below. For batch order requests consisting of multiple orders, each order will be counted individually. Error code 50061 is returned when the sub-account rate limit is exceeded. The existing rate limit rule per instrument ID remains unchanged and the existing rate limit and sub-account rate limit will operate in parallel. If clients require a higher rate limit, clients can trade via multiple sub-accounts.

• POST / Place order
• POST / Place multiple orders
• POST / Amend order

• POST / Amend multiple orders

• WS / Place order

• WS / Place multiple orders

• WS / Amend order

• WS / Amend multiple orders
  

Fill ratio based sub-account rate limit

This is only applicable to >= VIP5 customers.
As an incentive for more efficient trading, the exchange will offer a higher sub-account rate limit to clients with a high trade fill ratio.

The exchange calculates two ratios based on the transaction data from the past 7 days at 00:00 UTC.

1. Sub-account fill ratio: This ratio is determined by dividing (the trade volume in USDT of the sub-account) by (sum of (new and amendment request count per symbol * symbol multiplier) of the sub-account). Note that the master trading account itself is also considered as a sub-account in this context.
2. Master account aggregated fill ratio: This ratio is calculated by dividing (the trade volume in USDT on the master account level) by (the sum (new and amendment count per symbol * symbol multiplier] of all sub-accounts).

The symbol multiplier allows for fine-tuning the weight of each symbol. A smaller symbol multiplier (<1) is used for smaller pairs that require more updates per trading volume. All instruments have a default symbol multiplier, and some instruments will have overridden symbol multipliers.

The fill ratio computation excludes block trading, spread trading, MMP and fiat orders for order count; and excludes block trading, spread trading for trade volume. Only successful order requests (sCode=0) are considered.

At 08:00 UTC, the system will use the maximum value between the sub-account fill ratio and the master account aggregated fill ratio based on the data snapshot at 00:00 UTC to determine the sub-account rate limit based on the table below. For broker (non-disclosed) clients, the system considers the sub-account fill ratio only.

If there is an improvement in the fill ratio and rate limit to be uplifted, the uplift will take effect immediately at 08:00 UTC. However, if the fill ratio decreases and the rate limit needs to be lowered, a one-day grace period will be granted, and the lowered rate limit will only be implemented on T+1 at 08:00 UTC. On T+1, if the fill ratio improves, the higher rate limit will be applied accordingly. In the event of client demotion to VIP4, their rate limit will be downgraded to Tier 1, accompanied by a one-day grace period.

If the 7-day trading volume of a sub-account is less than 1,000,000 USDT, the fill ratio of the master account will be applied to it.

For newly created sub-accounts, the Tier 1 rate limit will be applied at creation until T+1 8am UTC, at which the normal rules will be applied.

Block trading, spread trading, MMP and spot/margin orders are exempted from the sub-account rate limit.

The exchange offers GET / Account rate limit endpoint that provides ratio and rate limit data, which will be updated daily at 8am UTC. It will return the sub-account fill ratio, the master account aggregated fill ratio, current sub-account rate limit and sub-account rate limit on T+1 (applicable if the rate limit is going to be demoted).

The fill ratio and rate limit calculation example is shown below. Client has 3 accounts, symbol multiplier for BTC-USDT-SWAP = 1 and XRP-USDT = 0.1.

1. Account A (master account):
   1. BTC-USDT-SWAP trade volume = 100 USDT, order count = 10;
   2. XRP-USDT trade volume = 20 USDT, order count = 15;
   3. Sub-account ratio = (100+20) / (10 * 1 + 15 * 0.1) = 10.4
2. Account B (sub-account):
   1. BTC-USDT-SWAP trade volume = 200 USDT, order count = 100;
   2. XRP-USDT trade volume = 20 USDT, order count = 30;
   3. Sub-account ratio = (200+20) / (100 * 1 + 30 * 0.1) = 2.13
3. Account C (sub-account):
   1. BTC-USDT-SWAP trade volume = 300 USDT, order count = 1000;
   2. XRP-USDT trade volume = 20 USDT, order count = 45;
   3. Sub-account ratio = (300+20) / (100 * 1 + 45 * 0.1) = 3.06
4. Master account aggregated fill ratio = (100+20+200+20+300+20) / (10 * 1 + 15 * 0.1 + 100 * 1 + 30 * 0.1 + 100 * 1 + 45 * 0.1) = 3.01
5. Rate limit of accounts
   1. Account A = max(10.4, 3.01) = 10.4 -> 2500 order requests/2s
   2. Account B = max(2.13, 3.01) = 3.01 -> 1750 order requests/2s
   3. Account C = max(3.06, 3.01) = 3.06 -> 1750 order requests/2s

Best practices

If you require a higher request rate than our rate limit, you can set up different sub-accounts to batch request rate limits. We recommend this method for throttling or spacing out requests in order to maximize each accounts' rate limit and avoid disconnections or rejections.
