When looking for accumulation before any darkside move north. The Strong CMF is all you need to see. Doesn't matter if its negative or positive. Just needs to be during a stall channel and no increase or decrease in PPs is seen.
Accumulation could be big guys buying at the ask, in the stall channel or them buying at the bid!!
When anyone accumulates in a bottom stall, the PPs is the same! The accumulation seen in the CMF indicator, because of the fact that someone is doing allot if it, without effecting the PPs.
Shows who ever it is, knows what they are doing! If they didn't, the PPs would increase with strong buying pressure or decrease with strong selling pressure.
So any strong CMF buy or sell says someone knows how to accumulate with stealth!! And IMO thats a big guy setting up a move north!
