The idea is that say you take a buy order for 1 lot and would normally place a 150 pip TP and a 50 pip stop loss, instead you take a sell order for 1.4 lots. If price keeps going down another 150 pips you will make a small profit. If it goes back up to where you first took your order (this area is called the recovery zone), you open another buy order for 1 lot. If it goes up another 150 lots, once again you get out with a small profit where you would have taken a loss otherwise. Each time price reverses instead to the other side of the recovery zone then you open another trade. Eventually price will go up or down enough to be able to close all the trades. This means when you are right, you will hit your tp as you planned. When you are wrong, your trades will close at a modest profit. Once in a blue moon you will hit SL but it won’t devastate your account.
