Modify GTT Order

This API allows you to modify the price, trigger price or quantity of a pending GTT order.

USE CASE

Move your target or stop-loss after placing a GTT order, without cancelling it and placing a new one.

Details

This allows the user to modify pending GTT orders. Users can provide parameters which need to be modified. In case a particular parameter has not been provided, the original value will be considered.
Send the order id and orderInfo. leg1 is mandatory for every modification, and leg2 is required if the order is an OCO.
Only the price, trigger price and quantity of each leg can be updated. The request has no field for symbol, side or product type.
For an OCO order, the leg1 trigger price must stay above LTP and the leg2 trigger price must stay below LTP.
Response code 1102 means the order was modified. Code 201 means it is in transit, so confirm it in the GTT Order Book.
Rate limits differ between the Standard and Prime plans. See Plans & rate limits.
