Where can I see my GTT orders?

In case the trigger is pending, 

You can view your open GTT orders in the Orders tab under the GTT orders section.

The order is placed on the exchange, once the trigger is hit.  

If the order is executed on exchange - your holdings/position is updated. 

If the order is pending for execution - you can view your order in the orders tab - under open order. 

You can also view your order history by going to  “All orders” and then to GTT
