This Indicator plots a single Daily DSP (Detrended Synthetic Price) and a Daily ELI (Ehlers Leading Indicator) using intraday data. Detrended Synthetic Price is a function that is in phase with the dominant cycle of real price data. This one is computed by subtracting a 3 pole Butterworth filter from a 2 Pole Butterworth filter. Ehlers Leading Indicator gives an advanced indication of a cyclic turning point. It is computed by subtracting the simple moving average of the detrended synthetic price from the detrended synthetic price. Buy and Sell signals arise when the ELI indicator crosses over or under the detrended synthetic price. See "MESA and Trading Market Cycles" by John Ehlers pages 64 - 70.
