The FM Demodulator Indicator was created by John Ehlers (Stocks and Commodities May 2021 pg 14) and this indicator was created to accurately time any price variations which I think it does a great job. It is smoothed by default with his super smoother but feel free to substitute your own and try different combos. Buy when the line turns green and sell when it turns red.
Let me know if there are any other indicators you would like to see me publish!
