I am also a option buyer & loosing trader. After maintain journal of every single trade of last 6 month I have realised that to make money in option buying One has to limiti loss per day (EX 10k per day) and holding winning trade & add quantity in winning trade to maximise profit is the only way.
Bet more on PUT buy than Call buy. add after pullback when buy call. add on signal or breakdown while PUT buy.
by doing that many winning trade can turn into small loss or breakeven. but when you will be right you can make huge money to cover all the loss and make handsome money.
9 to 10 days out of 22 trading session Bank nifty move significantly to make good money. but 2 3 days is the day when you able to make huge money.
The main think is to wait patiently for that trade is huge challange psychologically. and you dont know when that will happen, so every day you have to follow a single rule and execute it without any hesitation or emotion.
Fear of loss by taking SL is less than fear of profit turn into loss. so 90% people not able to hold & add to winning position.
