on balance volume and chaikin money flow

You may have seen the Chart School article on CMF here

I think CMF might be compared to Chaiken's Accumulation/Distribution indicator instead of OBV - OBV and Chaikin A/D sort of do the same thing, but Chaiken's calculation is more complicated. In any case, CMF is a measure of momentum in the Chaiken A/D.

It might help to put one beside the other, but the CMF calculation is based on the A/D, so it will vary with the A/D. In any case, as the article suggests, the indicator is meant to be compared to price and divergences indicate possible turns in price.
