Please note that trigger price only decides the price at which the order will be placed at the exchange, this doesn’t decide the execution price.
But, to save you from very offset prices, Groww places market orders triggered through OCO as limit,
for e.g., your Sell SL Trigger was Rs. 100, and you didn’t give any limit price, we place your normal sell order at a limit of Rs. 90 (10% below trigger),so that this doesn’t execute below Rs. 90.
