Is it possible to modify a GTT Order?

Yes, scheduled legs of a GTT Order can be modified under specific conditions:

For fresh GTT Orders:

If the primary leg is not triggered, you can modify the price and add or delete legs as required.

Once the primary leg is triggered, you can only modify the price. You can’t add or delete the Stop-Loss (SL) or Target legs.

For GTT Orders on existing Positions and Holdings:

After the order is placed, you can only modify the price. You can’t add or delete Stop-Loss (SL) or Target legs
