## The Anatomy of a Trade Fill

A trade fill, or execution, is the successful completion of a buy or sell order for a security. When a [smart trading system](https://prime.greeks.live/question/what-are-the-key-differences-between-a-smart-trading-engine-and-a-traditional-algorithmic-trading-system/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) sends an order to an exchange or other liquidity venue, it receives a series of messages back from the venue. These messages, typically formatted using the Financial Information eXchange (FIX) protocol, provide real-time updates on the status of the order. The most important of these messages is the [Execution Report](https://prime.greeks.live/question/what-are-the-key-differences-between-a-regular-execution-quality-review-and-an-annual-best-execution-report/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), which confirms that the order has been filled and provides the details of the trade, including the execution price, quantity, and time.

## The Fill Verification Workflow

The fill verification workflow can be broken down into the following steps:

- **Receipt of FIX Execution Report** ▴ The process begins when the smart trading system receives a FIX Execution Report from the trading venue. This message contains all the details of the trade, including the execution price, quantity, and time.

- **Parsing and Validation** ▴ The smart trading system parses the Execution Report and validates its contents to ensure that it is well-formed and contains all the required information.

- **Order Matching** ▴ The system then matches the Execution Report to the corresponding order in its database. This is typically done using the ClOrdID (Client Order ID) and OrderID (Exchange Order ID) fields in the FIX message.

- **Reconciliation** ▴ Once the order is matched, the system reconciles the trade details from the Execution Report with the order information in its database. This includes verifying the price, quantity, and symbol.

- **Exception Handling** ▴ If any discrepancies are found during the reconciliation process, the system generates an exception and routes it to the appropriate team for resolution.

- **Updating Position and P&L** ▴ Once the fill is verified, the system updates the firm’s position and profit and loss (P&L) records to reflect the trade.

## Exception Handling

A robust exception handling process is a critical component of any fill verification strategy. The smart trading system should be configured to automatically detect and flag any discrepancies between the Execution Report and the order information. The system should also provide a user-friendly interface for investigating and resolving exceptions. Common types of exceptions include:

- **Mismatched Prices** ▴ The execution price in the Execution Report does not match the expected price.

- **Mismatched Quantities** ▴ The executed quantity in the Execution Report does not match the order quantity.

- **Unmatched Fills** ▴ The system is unable to match an Execution Report to an order in its database.

> An effective exception handling process is essential for maintaining data integrity and mitigating the risk of financial loss.
