I want to know how to add EMA in Elder Force Index indicator in Pi??
I checked a blog and Mr. Kamath said custom indicator can only be added through backend.
If this is the case, add this in backend as I wish to use EMA in Elder Force index.
Force Index(1) = {Close (current period) - Close (prior period)} x Volume Force Index(13) = 13-period EMA of Force Index(1)
