Descrição
⋅ 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[n])
Volatility = n ∑(ABS(Close – Close[1]))
n = The efficiency ratio period.
This version features volatility and volume filter and custom performance module.
