Modify Single Order

This API allows you to modify an existing order.

USE CASE

Change the price, quantity or trigger price of an order that is still pending.

Details

This allows the user to modify a pending order. User can provide parameters which needs to be modified. In case a particular parameter has not been provided, the original value will be considered.
Modifying orders needs an app with the Order Placement permission.
Only pending orders can be modified. The id of the order and its type are always required.
Prices must be multiples of the symbol tick size, and quantity must follow the lot-size rules.
Modify requests count towards the limit of 10 orders per second shared with placing and cancelling. Requests beyond it are rejected.
To cancel only a linked Take Profit or Stop Loss, pass null for takeProfit or stopLoss. Pass both as null to cancel both.
If the response code is 201, the request was made but not acknowledged. Check the order book before sending it again.
For order types, product types, validations and sync vs async behaviour, refer to the Order Placement Guide.
When order rate limiting is triggered, the API returns 429 Too Many Requests.
Retry timing is provided through response headers, not in the response body.
Retry-After — Wait time before retrying, in seconds
X-Retry-After-Ms — Wait time before retrying, in milliseconds
Use the retry interval returned in the response headers before sending another order request.
Rate limits differ between the Standard and Prime plans. See Plans & rate limits.
