已更新 Trend Extractor
First off, I'm a huge John Ehlers admirer. Been learning a lot from him. This indicator was inspired by his Super Bandpass Filter.
The goal of this indicator, which I'm calling "Trend Extractor" for lack of a better name, is to identify trends and filter out choppy market movements, similar to the Super Bandpass Filter,... but arguably more customisable. Personally, I've had better results with this Trend Extractor.
A brief overview of how it works:
The price changes are averaged over the lookback period using the Arnaud Legoux Moving Average (ALMA), which has been chosen for its superb versatility.
For instance, with Offset 1 and Sigma 0, it behaves like a SMA, and with Offset 1.1 and Sigma 2, it behaves like a WMA. So, feel free to tweak and experiment.
The purple lines are the positive and negative root mean square (RMS) of the main line, and act as signal lines.
The higher the Smoothing, the smoother the main line, at the cost of greater lag. Default is 1, that is, none. I'd suggest going not higher than 5.
Signals are straightforward to interpret. Trending up when green, trending down when red, and ranging when gray.
Your feedback is very well appreciated. Thank you. :)
