If a user has already subscribed to the books-l2-tbt order book channel for a specific trading symbol within the same connection and then decides to subscribe to the books50-l2-tbt/books channels, we will retain the user's books-l2-tbt subscription since it provides more depth of the order book and is prioritized in the push sequence. An error code 64004 will be returned for the new subscription. An example is provided below.

Request Response
{
    "op": "subscribe",
    "args": [
        {
            "channel": "books",

 } 


If a user has already subscribed to the books50-l2-tbt/books order book channels for a specific trading symbol within the same connection and then decides to subscribe to the books-l2-tbt channel, we will make new subscriptions to the books-l2-tbt channel and then cancel the user's existing books50-l2-tbt/books subscriptions. This is also because the books-l2-tbt channel provides more depth and is prioritized in the push sequence.

Note that the unsubscription process may have a delay of a few seconds, meaning the user might continue to receive messages from the old channels for a few seconds after successfully subscribing to the new channel.

To enhance system stability and fairness to users, the exchange starts to impose limitations on the number of concurrent WebSocket connections allowed to subscribe to the following WebSocket channels. The limit will be set at 20 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",

Parameter Type Description
alias String this_month next_month
Not recommended for use, users are encouraged to rely on the expTime field to determine the delivery time of the contract


Notice for new monthly futures contracts generation and alias field change


Currently, the BTC/USDT- and BTC/USD-margined futures contracts are different in number from futures contracts in other margins, the supported expiration dates are different, and the rules for contract rotation are also slightly different. As indicated in previous announcement, OKX recommends that users should use the expTime field of instruments REST endpoint and WebSocket channel to determine the expiration dates of futures contracts and disable alias field.


OKX has expanded the available durations for BTC/USDT- and BTC/USD-margined futures contracts to the following: weekly, bi-weekly, monthly (new duration), bi-monthly (new duration), quarterly, and bi-quarterly at 8:00 am UTC on November 17, 2023. Before adjustment, we only support the following 4 durations: weekly, bi-weekly, quarterly, and bi-quarterly. Following this adjustment, all the available expiration dates for newly listed contracts will be as follows:

  1. Weekly (this_week): November 24, 2023
  2. Bi-weekly (next_week): December 1, 2023
  3. Monthly (this_month): December 29, 2023. Before adjustment, it is a quarterly contract. If you use the alias field to determine the expiration date, you may mistakenly think that the expiration date is November 24, 2023.
  4. Bi-monthly (next_month): January 26, 2024. Newly listed contract.
  5. Quarterly (quarter): March 29, 2024. Before adjustment, it is a bi-quarterly contract. If you use the alias field to determine the expiration date, you may mistakenly think that the expiration date is December 29, 2023.
  6. Bi-quarterly (next_quarter): June 28, 2024. Newly listed contract.

After adjustment, the alias field of instruments REST endpoint and WebSocket channel will have new enumeration values, this_month and next_month. For now, the new enumeration values are only applicable to BTC/USDT- and BTC/USD-margined futures contracts. In the future, OKX may expand the available durations for more futures contracts. Please use the expTime field of instruments REST endpoint and WebSocket channel to determine the expiration dates of futures contracts and disable alias field.

Adjustment to pending order limit for trading symbols

After the adjustment, the maximum number of pending orders per trading symbol is 500. For example, for the perpetual swap contract BTC-USDT-SWAP, the futures contract BTC-USDT-230707, and the spot BTC-USDT, each supports a maximum of 500 pending orders.

The maximum number of pending orders per account remains unchanged at 4000. The existing rules for options trading are not changed. For users who have more than 500 orders for a trading symbol, the new limit does not affect existing orders. However, users are not able to place new orders for that trading symbol until some of the existing orders are filled or canceled so that the number of pending orders for the trading symbol is below the limit.

The limit of 500 pending orders applies to the following order types:
