Self-Trade Prevention

Self-trade prevention can be enabled on a CLOB order.

When an incoming order would match a resting order from the same account, the resting maker order is canceled instead of executing the self-trade. The incoming order then continues matching against other eligible liquidity.

Self-trade prevention is optional and is scoped to a trading account:

• orders from the same account are treated as self-liquidity;
• orders from different subaccounts are not, even when the same wallet owns both accounts.

If self-trade prevention is not enabled, orders from the same account may match.
