This Volume Flow indicator shows both in flow and out flow volume . In June, at the current bottom, you can see sell pressure peaked dramatically, and has since waned. Buy pressure, conversely, and gained momentum. They finally crossed over on the weekly. In my previous idea I point out how this same, particular Volume Flow indicator signaled the end of the 2018 bear, and has generally crossed over at huge swings in momentum. This is very speculative of course, but it will be very interesting to see if it actually reversers momentum.
