Upcoming Changes

Changes for funding rate mechanism

OKX plans to adjust the perpetual contract funding mechanism to provide a better service. After adjustment, funding fees for certain contracts are calculated based on the funding rate at the time of the current funding fee collection.

For some altcoins perpetual swaps with significant fluctuations in funding rates, OKX will closely monitor market changes. When necessary, the funding rate collection frequency, currently set at 8 hours, may be adjusted to higher frequencies such as 6 hours, 4 hours, 2 hours, or 1 hour. Thus, users should focus on the difference between fundingTime and nextFundingTime fields to determine the funding fee interval of a contract.

The API change will be released in demo trading environment on 7 December and in production on December 13.

Timeline of changing the funding rate mechanism for perpetual swap contracts will be announced separately.

The change at API end is listed below.

Parameter Type Description
method String Funding rate mechanism
current_period
next_period
nextFundingRate String Forecasted funding rate for the next period
The nextFundingRate will be "" if the method is current_period

Set time range limit for interest accrued data endpoint

OKX plans to set time range limit for interest accrued data endpoint. After adjustment, users can only get interest accrued data within one year. The change has been released in demo environment and will be in production around mid December.

Cancel all after endpoint update

NOTE: when the cancel all after is triggered, OKX trading engine will cancel orders on behalf of the client one by one and this operation may take up to a few seconds. This feature is intended as a protection mechanism for clients only and clients should not use this feature as part of their trading strategies.

Block trade public transaction data endpoint migration

OKX plans to migrate block trades market data endpoint to a new one. The new endpoint has been released in production. The corresponding old one will be offline in 30 November. Please migrate to new endpoint as soon as possible.

Lot size change for perpetual and futures contracts

OKX plans to reduce the minimum notional value for perpetual swap and futures contracts by adjusting the lot size. Currently, the minimum order size and lot size for these contracts are always 1, with quantities being integers. OKX will change the minimum order size and lot size to values such as 0.1 and 0.01 (in exponents of 10), which will effectively lower the minimum notional value per order, with minimum order size the same as lot size. This means that quantity values for orders, trades, and positions will be returned as decimal values in multiples of the lot size.

When OKX executes the lot size change, the updated lot size information will be broadcasted through the websocket instruments channel and the instruments REST endpoint, similar to other instrument configuration changes. Clients should programmatically handle the change. The contract value of the contracts will remain unchanged. For example, the contract value of BTC-USDT-SWAP is currently 0.01, which means the minimum notional value per order is 0.01 BTC. With the minimum order size and lot size changed to 0.1, the minimum notional value per order will become 0.01 BTC x 0.1 = 0.001 BTC. New contracts may also be listed with decimal lot size.

In the demo environment, the minimum order size and lot size of some contracts will be adjusted to 0.1 for clients to test in mid December. The adjustment of the minimum order size and lot size for other contracts will start from Jan 2024. The list of contracts and the effective date of the changes will be announced separately.

Any upcoming updates, including the timeline etc., will be updated through this article.

Savings endpoints migration

OKX plans to migrate savings endpoints to the new. The new endpoint has been released in production on 2023/03/15. The corresponding old endpoints will be offline in late December. Please migrate to the new endpoints as soon as possible.

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.

Added new trading restriction


To ensure the high performance of the trading system and provide users with a better trading experience, OKX has now added a new trading restriction that the maximum number of maker orders that can be matched with a taker order cannot exceed 256.


When the number of maker orders matched with a taker order exceeds the maximum number limit of 256, the taker order will be canceled:

  1. The limit orders will only be executed with a portion corresponding to 256 maker orders and the remainder will be canceled.
  2. Fill or Kill (FOK) orders will be canceled directly.


When order is canceled due to this, users can get cancelSource = "0" and cancelSourceReason = "Order was canceled by system" through the endpoints below:


They can also receive cancelSource = "0" through the following WebSocket channel:


In the future, in order to adapt to more scenarios where orders are canceled due to improve trading system performance, the cancelSource and cancelSourceReason of this reason may be modified:

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:
