Partial Fills on Orders (Fixed Income Style Trading)

Many Fixed Income systems expect a single execution per order. OpenYield follows equity-style fill semantics: an aggressive order can receive multiple partial fills as it works through available liquidity, each delivered as a separate execution.

OpenYield always sends a final completion ticket once the order is fully filled, cancelled, or expired. Each partial fill and the completion ticket should be treated as individual executions on the same order.
