STP (Self-Trade Prevention)#
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. Conversely, 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.For spot STP, it should be noted that the STP function only occurs at the UID level, and spot already supports the master account level STP whitelist function.

Hidden Orders and Iceberg Orders (Hidden & Iceberg)#
Hidden orders and iceberg orders can be set in advanced settings (iceberg orders are a special type of hidden order). When placing limit orders or stop limit orders, you can choose to execute according to either hidden orders or iceberg orders.Hidden orders are not shown in order books.Unlike hidden orders, iceberg orders are divided into visible and hidden portions. When engaging in iceberg orders, visible order sizes must be set. The minimum visible size for an iceberg order is 1/20 of the total order size.When matching, the visible portions of iceberg orders are matched first. Once the visible portions are fully matched, hidden portions will emerge. This will continue until the order is fully filled.The system will charge taker fees for hidden orders and iceberg orders.
If you simultaneously set iceberg orders and hidden orders, your order will default to an iceberg order for execution.
