Sorry....

Sorry for my request...
I would like create a composite like for exemple ,
0.5 * ab #f + 5 *ym#f -- there's no problem its working
But I want also create an indicator to plot the composite volume.
like
Function main() {
var Russell = 0.5 * volume(0, sym("ab #f")
var ym = 5 * volume(0,sym("ym #f")
var VolABYM = ym + Russel
return VolABYM();
thank you for your help....

With the exception of some syntax errors you had the formula already written.
Alex

function main() {
    var Russell = 0.5 * volume(0, sym("ab #f"));
    var ym = 5 * volume(0,sym("ym #f"));
    var VolABYM = ym + Russell;
    return VolABYM;
}
