Some of you might've already heard of the Kaufman Efficiency Ratio as it can be an effective filter for Reversal/Mean-Reversion trading.
My idea of using the indicator is quite simple, I want to have a filter line that tells when market's volatility is above or below the trading objective.
And so instead of having a static line like this:

I attach the LWMA from the default Moving Average indicator, much better:

Problem is I've been trying to put together an EA using a software that doesn't require coding knowledge but this particular one with two indis being used as one is a challenging case.
Hope everybody finding this useful and happy to give me hand with the coding.
Thanks for reading!

Perhaps I should've wrote more clearly, basically I just need an indicator of the Kaufman Efficiency Ratio with Averages already attached to it as parameter options.
Hope to have some help of your expertise.
Much thanks!
