I have seen multiple threads where people need to tie back if the order was result of GTT trigger. Some one suggested to have tag in the orders while placing GTT. Is this feature supported if not is there any way to relate an order to the GTT.
GTT orders do not support the tag parameter directly. However, for regular orders, the tag field is useful for sending an arbitrary string to help track the order. In the case of GTT orders, you can use the returned trigger_id — which is provided upon order placement — to store and track the order as needed.
No man, trigger_id doesn't give the information about order, it can just tell if the gtt is triggered or not. As mentioned I want to know if a particular order is result of a particular gtt trigger.
