Exits are different in Intraday trading than in swing/trend trading, in a way that one is not focussed to gain from big moves. Big moves are not the center of an intraday traders gameplan, because such big days happen rarely; but trading happens everyday. Everyday, there is a trade or two to be taken, which gives 10 to 20 points gain. He is interested in making a home, one brick at a time. At the same time, it'd be his shortcoming if he exited at 20 points, in a 100 point move.
Success in intraday trading would be a result of two things done right:
1. Spotting good trades (leaving out the duds, the strugglers)
2. And Exits
(after MM, PS, discipline etc).
I hope to apply this in April.
