As per my knowledge Stop loss which we placed using Bracket order must be SL-M.
Because if it SL order it must ask us limit price to execute when we place an order but I did not saw an option like that and If it SL order and it not get executed when triggered along with us broker will also be in trouble because Broker is taking risk by giving us an option like Bracket order for their Business.
Yes, the stoploss order in a Bracket order is an SLM( Stoploss Market) order. For an SLM order, you only enter the trigger price. When the trigger price is reached, a market order is then sent to the exchange.
So if you place a Sell SLM order with trigger price at 100 when the stock is trading at 100, then if the stock price reaches or goes below 100, your SLM order is triggered and a Sell Market order is sent to the exchange.
i am a regular day trader from past 3 years…today i have experienced BO with SL (were you cant change the trigger price after execution & trigger & limit price is auto filled by zerodha which is again very huge differences)
