If we start with the beginning of the bar it's the Open. There are several possibilities. These are some main ones for this context: a) High volume BO in-line with higher black volume in trend, could go long though still early in bar (aggressive). b) High volume above previous close, but no BO yet, wait for confirmation. c) High volume but still inside OB, wait. d) High volume BO below OB, anticipate Change or at least long not interesting any longer. e) High volume BO below RTL, strongly anticipate Change and start considering reversal. f) Low volume BO. Less attractive than a) but could still go long, expecting some continuation (aggressive / chasing the market). g) No BO yet, wait. h) No BO yet, wait. i) BO below OB on low volume, anticipate short-term limited upside. j) BO below RTL on low volume, anticipate FBO or BO and forget longs for a while. Of these, none are particularly interesting at Open since we should wait for more data, but if aggressive (ie. high quality pick) could go long in a) or f). I think this should cover Open. Interesting cases to look further at is a) - c) and f) - h). They can each have High First or Low First, so will be at least 12 more cases, maybe more. d), e), i) and j) may be pruned out of further long-analysis. If this helps, I can continue with the interesting cases and High First or Low First, or if you have concrete suggestions I can attempt to incorporate them, though I'm not exactly sure how to now. EDIT: Maybe b) and c) can be merged together, as well as g) and h) as they're very similar? Also, maybe d)-e) and i)-j) not too bad depending on further price development, according to possible new channel forming, so shouldn't be pruned after all? Seems to be many possibilities.
