Cancel Replace (35=G)

Request a cancel/replace order over FIX API.

A Cancel/Replace Order message 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.
