DislikedHey Dan,
Yes, you want the nose portion to go past the low(when looking for a long), or past the previous bar(s) high(when looking for a short). The more the nose protrudes away from the previous bars the better a pinbar.
I may be missing your question if so please try me again and I will try to answer it right I promise!
Here is a chart with some pinbars and bars confused for pinsIgnored
Thanks Mbq!
