Binance Options to make self-trade prevention function mandatory for all clients
Binance will be making the Self-Trade Prevention (STP) function mandatory for all clients of Binance Options from March 19, 2026 06:00 (UTC).
With this update, all users are set to benefit from STP across Spot, Margin, Futures, and Options trading on the Binance platform.
The system update is scheduled to begin at 2026-03-19 06:00 (UTC) and is expected to last for 1 hour to allow for a smooth transition.
The STP function prevents API users from unintentional self-trades, ensuring compliance and the integrity of market data, while saving users unnecessary trading fees. It automatically blocks the execution of orders that would result in self-trades. A total of three STP modes are available, and the default STP mode enabled for all orders on Binance Options is “EXPIRE_MAKER”.
