Self-trade prevention

---

In the Diamonde.finance protocol, order interactions between the same address will trigger the direct cancellation of pending orders rather than order matching. No transaction fees are generated during this process, and the cancellation behavior will not be recorded in the transaction flow.

In centralized exchanges (CEX), this mechanism is often referred to as "Expire Maker". This design is particularly friendly to high-frequency market-making algorithms, allowing active orders to continuously match liquidity behind orders within the limit price range, thereby optimizing market depth and liquidity efficiency.

This mechanism effectively reduces unnecessary matching overhead while improving the stability and execution performance of the overall market microstructure.
