## Execution Report - Order Status

The response is an Execution Report containing the order's current state, with **ExecTransType (`20`)** set to `3` (Status).

<Tip>
  **lastShares (`32`)** and **LastPx (`31`)** contain the price and quantity of the most recent fill. A completed order has **LeavesQty (`151`)** = `0`. Note: lastShares was relabeled as lastQty in later FIX versions; the tag number and purpose are identical.
