What is the Mechanism of FIX Tag 59?

When an order with FIX Tag 59 is submitted, the trading system's order management component processes this parameter to determine the order's active lifespan. For a Good-Till-Cancel (GTC) order, the system maintains it until filled or explicitly cancelled. For a Day order, the system automatically expires it at the end of the trading session. In RFQ systems, TimeInForce can define how long a quote remains executable, impacting price freshness and potential for market impact. The system must accurately track and manage these order states.

What is the Methodology of FIX Tag 59?

Integrating FIX Tag 59 effectively requires robust order state management within the trading system architecture. A strategic methodology involves configuring the system to accurately interpret and enforce various TimeInForce values, ensuring consistent behavior across different crypto asset types and trading venues. This includes designing mechanisms for automated order cancellation or expiration, and for communicating these status updates back to the client. Precise implementation of this tag supports specific trading strategies and compliance with desired execution windows.

FIX Tag 59

Meaning

FIX Tag 59, representing “TimeInForce,” specifies the duration an order remains active in the market within the Financial Information eXchange (FIX) protocol. In crypto trading, this tag governs how long an institutional order, particularly within an RFQ system or an options trading venue, remains valid before expiration or cancellation. It dictates the execution parameters from a temporal perspective, affecting order handling logic. This tag is critical for managing order lifecycle and liquidity interactions.
