Theory:
Giorgos E. Siligardos, as a part of the leader of the MACD indicator, constructed a kind of a new moving average which we can call "leader EMA" (he calls it "a kind of a Zero lag EMA"). This is that new average as a standalone indicator.
Usage:
This indicator has 2 "coloring modes":

PS: example for the coloring mode when leader EMA crosses regular EMA
