Akhil,
I don't have a system right now. Over the past weeks, I have been trying out and discarding systems. The present phase of the market does not help any system at all, and now I am trading system-less
About my exits: Earlier, I used to have wide SL, sometimes 40 points wide, sometimes 10 points. But when a couple of those got hit, it took a major win to recover. So now, I have decided to keep tight SL, and move them to scratch point as soon as possible. Today, I have been keeping an initial SL of 8 points, and trying to move to my scratch point of +2 point as soon as possible (when the market moves in my favor).
I am targeting the big moves (which are not happening now), but trying not to loose too much in any single trade.
