Request a cancel/replace order over FIX API.
A Cancel/Replace Order message in the FIX API is used to modify or replace an existing order that has been previously submitted to the order management system. This message allows traders to adjust various parameters of an order without having to completely cancel it and submit a new one, thus helping to manage risk and optimize execution strategies.
The Cancel/Replace Order message allows traders to modify existing orders by updating parameters such as quantity, price, and time in force without canceling and re-entering the entire order. This functionality is crucial for managing orders effectively and adapting to changing market conditions while minimizing disruption to trading activities.
