About

Double Smoothed EMA (DSEMA) is two EMAs back-to-back with a lag-cancelling combination. Tighter than a plain EMA at the same length, simpler than DEMA/TEMA.

Use as the fast leg in a crossover with a slower MA.
Raise N to slow the line, lower it for tighter turns.
Pairs well with an ADX > 25 filter.
