Most of the breakthroughs are ultimately fake breakthroughs, which means that the market is not actually moving in the direction of the break and is simply trapped by professional traders to lure traders to break in the wrong direction. Using confirming price action on a retest also provides you with a great place to “hide” your stop loss. As you may well know, you always want to place your stop loss at a level where the setup is invalidated if hit. Waiting for confirming price action gives you the perfect opportunity to do just that. When a bullish or bearish pin bar forms on a retest, you can use the tail of the pin bar as your invalidation level. In other words, if the market moves past the tail the setup is no longer valid.
