Definitely I will make some changes to my trading habits/style from this november........and I have lost around 2 lakhs in 10-15 expiry days alone in options.....so something must be done to stop this expiry day gambling.......may be only futures from now on...or no more than 2-4 lots of options at a time.......
Exactly same thing happened with me when I started trading in options some 5-6 months back. But then I chnged my trading style. Now I take 2-3 trades max in a month. As such these trades r all meant to capture bigger swings. Also before taking any trades I prepare a powerpoint ppt containing reason why I should take this trade, my exact entry, exit rules, sizing etc - to justify to myself whether I really should take this trade.
Needless to say, my impulsive trades got filtered out in this process. Also after initiating the trade, if it tanks i diagnose wht went wrong and keep that recorded in the same ppt. It helped me learn a lot. Learnings were mostly those common trading guidelines like buy in an uptrend, sell in a downtrend, buy above previous swing high etc etc... But maintaining records pointed out to me how often I violate rules while trading.
