@prabuddhasanchi, Please check your RISK appetite for the stoploss. Trading is a probability business not a certainty one. If analyze dint work 2% stoploss in F&O is almost 20000 to 25000/- per lot, according to me losing 1 to 2% capital on a single trade is a gambling. So you must have atleast 25 lakh to take this trade in F&O. Also you can't book partial profit in F&O's.
Position Sizing are very important for a trade
