After the fee rate adjustment (For details, please refer to OKX Will Upgrade the Fee Rate System), all currency pairs will be in the same fee rate category. Futures and perpetual contracts will have different fee rates depending on whether they are USDT-margined or crypto-margined. The following adjustments will be made to Live Trading on May 7, 2022.
- The 'category' field will be removed, but it will not affect the existing program calls. A request returns the same data with or without the category value. This is because all currency pairs will be in the same fee rate category.
- Newly added return parameters: takerU and makerU, representing the fee rates of USDT-margined futures and perpetual contracts. When users check the fee rates of futures and perpetual contracts, the meaning of the original taker and maker parameters will change, representing only the fee rates of crypto-margined contracts. This is because futures and perpetual contracts will have different fee rates depending on whether they are USDT-margined or crypto-margined.
The interface path remains unchanged. Request parameters and return parameters after the adjustment are as follows.
