Augubhai,
If the you are trading Multiple lots in excess of 10 Lots...then book profit on partial...so that you get to breakeven...and can re-enter the exited lots...incase NF moves down by 10-12 points from your entry....
This thing of booking partial lots...will require a bit of practice..... & moreover... your 3 & 5 MA is perfect..... I know somebody who started with a single lot with this MA had moved to 20 lots last time when he posted here which was almost more than a year back...don't know presently how much he does...
