# Execution Reports - Fills

> Partial fill and filled execution report message formats and fields.

## Execution Reports – Fills

Paxos sends fill Execution Reports as orders match against the order book:

* **Partial Fill** (**ExecType (`150`)** = `1`) — Sent for each individual fill. **lastShares (`32`)** and **LastPx (`31`)** contain the fill quantity and price.
* **Filled** (**ExecType (`150`)** = `2`) — Sent when the order is completely filled. **LeavesQty (`151`)** = `0`.

<Warning>
  Market buy order executions are captured in **Partial Fill** messages. The **Filled** message for market buys is a summary confirming the order is closed — it does not represent an additional execution.
</Warning>
