Here's another example. In this case I wasn't a buyer, I was a seller at the low and closed i a small profit, but the break of the H12 high was only by 1.1 pips in this case, by a M5 pinbar (the M1 fakeout bar itself wasn't a pinbar):
H12 chart:
M5 chart:
This one didn't retrace 50%, but a break of the pinbar low in both cases would have resulted in a good profit. More risk entering just on the pinbar though, I suspect adding the retrace criteria would be a lower risk option.
