nifty option trade review

in the morning one trade was given to buy nifty option 4800 pe at aroun 65 68 rs with target of 82 and 90 plus also with the stoploss of 58 strict..the nifty put went upto to 82 very fast and came down again later it shot back once again and reached 97 .i always use stop loss method to trade nifty options..even if we consider 70 as our nifty option cost price we easily made a profit of 18% in a few hours ..i would prefer to take at least 2 lots of nifty option whenever a trade is executed .one lot should be booked at target 1 and once target 1 is achieved change the stop loss to cost price plus 2 rs
