The Simple Deriv Indicator was created by John Ehlers (Stocks and Commodities June 2021 pg 10) and this is a heavily modified version of his original script that changes the buy and sell signals. I did testing with his original settings but they didn't seem to be very profitable for most stocks so I created my own system. This indicator does have a lag though so it is best used for trend confirmation imo. 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!
