how to get macd value of certain stock while applying an efs to another stock?

[clearpicks]

I want to write an efs to get the value of indicator (i.e. MACD) of certain stock while this efs is applied to another stock. The purpose of this efs is to calculate this indicator:

Any help is greatly appreciated.

Hi,

I don't think there is currently a good way of doing this using the bulitins.

You could write the macd from scratch in efs, and that would work. There is a macd.efs in the library directory - but this one uses an SMA, but you could use it as a start.
