I’ve been using my automated system for over 2.5 years at the time of writing this answer and I have never set a stop loss. When you set a stop you WILL take a loss; I don’t like to lose. My trades are designed to scale in (add trades) if the market price goes against the original trade and by doing that we pull the take profit (TP) price closer to our current position; due to the fact that the market prices wave up and down this gives us no-loss forex trades by trading with a “basket” of trades.
