Hi Chandrashekhar
You could try
Mov(Vol,LastValue(X+PREV-PREV),E)
or work with the following EMA formula to input your own value of "X".
{Exponential Moving Average}
n:=Input("Periods",1,999,10);
R:=2/(N+1); {ratio of new data added each bar}
M:=If(Cum(1)=1,C,PREV*(1-R)+C*R);
M;
Either way, you probably need to use PREV. If "X" is a "fixed" variable, i.e., it always stays the
same, then all you need to is put LastValue() around it and it will work, but if it changes for each
bar then there's no escaping PREV.
Kind regards

PS: There'll be some information on LastValue(X+PREV-PREV) in the October newsletter.
