ema() on internal function()

[wildfiction]

I want to do something like this:

main() {
...
   var xx = ema( custom() );
...
}

function custom() {
    return (close(0) - close(-1)) * 3.14;
} 

But I can't seem to get that syntax to work. Any ideas?

You need to use efsInternal() to call the function. See the EFS Help in the Formula Editor for more information on the function

Thanks Alexis - that worked a charm.
