https://www.prorealcode.com/prorealtime ... ion-cycle/The Correlation Cycle Indicator was created by John Ehlers (Stocks & Commodities TASC).
Was designed for trend direction and trend strength and simply buy when it is green and sell when it turns red. Also keep in mind that the higher the indicator is above the signal then the stronger the trend and when they are close together, conditions get choppy.
