• A general “rule of thumb” is that you want to see the pin bar tail be two/thirds the total pin bar length or more and the rest of the pin bar should be one/third the total pin bar length or less. On a bullish pin bar formation, we will typically buy on a break of the high of the pin bar and set our stop loss 1 pip below the low of the tail of the pin bar. On a bearish pin bar formation, we will typically sell on a break of the low of the pin bar and place a stop loss 1 pip above the tail of the pin bar.
