Modify Stop Loss & Target

This API allows you to modify the Stop Loss and Take Profit of an open position.

USE CASE

Tighten a stop loss as the price moves in your favour.

Details

This allows the user to modify the Stop Loss and Take Profit for an existing open position. User can provide the parameters that need to be modified. In case a particular parameter has not been provided, the original value will be considered.
Send only what you want to change. A stopLoss or takeProfit you leave out keeps its original value.
positionId is mandatory, for example NSE:KWIL-EQ-INTRADAY. qty is optional and its maximum is the position quantity.
legType is optional: 1 = offset, 2 = percentage.
To remove a level instead of changing it, pass null for it. See Cancel Stop Loss & Target.
This is the Positions API, for an open position. To change Take Profit and Stop Loss on an order that is still pending, see Modifying TPSL in the Order Placement Guide.
Rate limits differ between the Standard and Prime plans. See Plans & rate limits.
