I have had a couple of folks sending me private mails to suggest that with stoploss so tight in a really volatile set I am asking to be stopped out.
To answer the question, I don't usually use a particular pip amount to set a stoploss. I put a stoploss at a point at which if my reading of this market is right then my stoploss shouldn't be hit. When it's hit then I admit I was wrong and move on to another installment.
