Efficient Trend Step Mod (v.3)

This is a version 3 of my mod of the script by alexgrover - Efficient Trend Step.

The logic is based on calculation of Kaufman's efficiency ratio (ER):

ER = Direction / Volatility
where:
Direction = ABS (Close – Close)
Volatility = n ∑(ABS(Close – Close))
n = The efficiency ratio period.

This version features volatility and volume filter and custom performance module.

Notes de version:

Rebrush of the script logic.
