D_ELI (Ehlers Leading Indicator) Strategy Backtest

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.

unfortunately this strategy is bogus and results are completely impossible
Does it repaint? Could you explain the repainting issue? Very interesting work.
Very interesting. Does this ever repaint the arrows?
HPotter txnemo
@txnemo, Yes. In real time arrows will be painting, but if you make a refresh then arrows will repaint again and it will be different from real time.
txnemo HPotter
@HPotter, could you explain more, I don't understand?
txnemo HPotter
@HPotter, also I bought the book by Ehlers and am still trying to understand the logic. Could you explain the reasoning behind it a little more?
HPotter txnemo
@txnemo, Arrows it is only from script logic. About Ehlers logic I can't say any more.
@HPotter, i just continually refreshh and its correct --- right? i am going to use some of this.
HPotter ghettotroof
@ghettotroof, Yes. Theoreticaly you can change xHL2 = security(tickerid, 'D', hl2) to xHL2 = security(tickerid, 'D', hl2) and it will be stable on the intraday data.
