DislikedHey Mikali
Basically, and this isn't a hard fact it can happen many ways....Ignored
So, if I understand you correctly you are suggesting that a small sized (in relation to the adjacent bars) PB on a Friday could indicate profit taking. That being the case, other then the size of the bar could there be any other forewarning clue that might determine if the PB is a valid set-up as apposed to profit taking i.e. volume for instance.
