Background
Inspired by NILX's "Tool: Chop & Trade Zones". This can used as an element for trading system control.
Function
I use my own customized algorithm to replace that core of NILX one, which is targeting to provide smoother and trend for chop and trend judgement.
Since it is quite different now but an oscillator within range of 0~100. The pro is it can use the constant threshold values for all time frames and all trading pairs now.
