Why is anybody's interpretation.
The only thing that I can tell is that the Cumulative Tick measures the number of price upticks minus the price downticks for all the NYSE traded stocks. It is therefore a very wide measure of accumulation/distribution that tracks mainly small stocks (because there are more small than large stocks).
The 20DMF tracks the LEV pattern of large stocks and hence tracks the accumulation/distribution of large players.
In other words, the cumulative tick might be closely linked to IWM moves why the 20DMF is linked to SPY moves.
