Volume involved with the trading action. Looking only at the chart. You have to realize ALL OTC Darkside manipulated runs involve Funders selling large amounts of new issued shares into the run.
So if the run involves large amounts of volume. They are the only ones able to feed the retail herds emotion BUYING more frenzy. With free trading OTC plays, there is no one with large amounts of shares for sale, selling into the move. So you may see the price go high, but the volume is average, for the price range. Because only other retailers are playing.
The emotion action is the same, thus you may see large price action. But volume is much smaller. Retailers watching don't hold hundreds of millions of shares to feed the emotion frenzy.
Keep in mind single zero stocks: strong average volumes run in the millions, double 10 millions and triple zero hundreds of millions are average volumes.
