Focus on your overall equity and view all your trades as a whole. Yes, the decisions made must be individual, but when you focus on a larger picture you are less emotional about the individual pairs. I don’t notice when a pair backs down too much. I just see my equity move up and down. I however as long as it’s more than my net balance I know I’ll be okay in the long run. Thus far this year, and we are close to 100 trades now, my equity has not fell lower than my account balance.
That is how you maintain consistent profitability.
