Dislikedwhat i am about to say may sound stupid but its not if you have 1000 account and you are trading 1pips $0.10 you dont need SL why i said this, all you need to do is to work on ur entries trading very lower than ur balance give you a good sound sleep because 100pips mean nothing to ur $1000 balance its just $10 loss if you decide to Breakeven 70% of times we dont see 100pips in a day until days. your SL is to lower ur risk that why some people trade options because it lower there risk since options is based on expiring date.Ignored
And get rid of all ratio maths, risk etc
