If this is the equation. And you have two symbols as !ny-a (for advance issues) and !ny-d (for declining issues). How does that read both. I am still learning and confused. It keeps giving me error code. I am doing something wrong.
/* McClellan Summation Index */ Graph0 = Cum( Ema( AdvIssues()-DecIssues(), 19 ) - Ema( AdvIssues()-DecIssues(), 39 ) );
