iMA is your friend ... https://docs.mql4.com/indicators/iMA ... :-)
double a=iMA(...20...,1)-iMA(...50...,1);
double c=iMA(...20...,2);

i know to write movingh averge less moving average but this result less bar behind it s the problem
a= ima(null,0,20,0,mode_sma,mode_close,0) -ima (null,0,50,0,mode_sma,mode_close,0);

b= a - bar behind a ???? a- a(-1) ???
this is a problem

ima(null,0,20,0,mode_sma,mode_close,1);
last number is bar shift .. 0 is the currend bar, 1 is the last closed bar before, 2 is 2 before ...
so .. a=ima(null,0,20,0,mode_sma,mode_close,0) and b=ima(null,0,20,0,mode_sma,mode_close,1) in your example
