Self-Trade Prevention is an option in advanced settings.It is not selected by default. If you specify STP when placing orders, your order won't be matched by another one which is also yours. On the contrary, if STP is not specified in advanced, your order can be matched by another one of your own orders. It should be noted that only the taker's protection strategy is effective.
It should be noted that the STP function only occurs at the UID level, and the Futures does not support it for the time being. The spot has already supported the STP whitelist function at the master-account level.
