[//]:content-type-MARKDOWN-DONOT-DELETE Dear Users, Gate.io continuously enhances the trading system to provide a better experience and safer environment for users. We attach importance to monitoring and preventing market manipulation, including self-trading. To protect user interests, we have launched a Self-Trade Prevention (STP) function for futures markets. Self-trading refers to users or a group of related users trading with themselves, which may disrupt price discovery, distort supply and demand data, and affect market fairness. On Gate.io, intentional manipulation of self-trading behaviour is strictly prohibited. However, not all self-trading is intentional. Some users may accidentally match their own two orders while running different trading strategies at the same time, and such unintentional self-trading will also have a certain impact on the market. Therefore, we have launched a Self-Trade Prevention (STP) for futures markets to help users avoid the risk of self-trading. Gate.io futures API users can enable Self-Trade Prevention (STP) from March 15, 2023 onwards. The STP function blocks orders that would result in self-trading. Users can configure STP to invalidate maker, taker, or both orders upon a self-trade. Parameters can be tailored to ensure trading strategies are not impacted by unintended self-trades. We continuously improve our trading system to provide a better experience and safer environment. The futures Self-Trade Prevention (STP) is another initiative safeguarding our user interests. We aim to deliver stable and efficient trading services. Please see our [API documentation](https://www.gate.io/docs/developers/apiv4/en/#self-trade-prevention-stp "API documentation") for STP function details. Submit an application to enable the self-trade protection mechanism. Thank you for your ongoing support. We will remain committed to delivering superior services and experiences.
