new John Ehlers indicator Forward Reverse EMA

Francesco78 · 2017-06-27T10:14:07+00:00

Hello, from the last video of better system trader I discovered this new indicator from John Ehlers He gave the code in Easylanguage that you can find here http://downloads.bettersystemtrader.com/files/ForwardReverseEMA.txt { Forward / Reverse EMA (c) 2017 John F. Ehlers } Inputs: AA(.1); Vars: CC(.9), RE1(0), RE2(0), RE3(0), RE4(0), RE5(0), RE6(0), RE7(0), RE8(0), EMA(0), Signal(0); CC = 1 – AA; EMA = AA*Close + CC*EMA[1]; RE1 = CC*EMA + EMA[1]; RE2 = Power(CC, 2)*RE1 + RE1[1]; RE3 = Power(CC, 4)*RE2 + RE2[1]; RE4 = Power(CC, 8)*RE3 + RE3[1]; RE5 = Power(CC, 16)*RE4 + RE4[1]; RE6 = Power(CC, 32)*RE5 + RE5[1]; RE7 = Power(CC, 64)*RE6 + RE6[1]; RE8 = Power(CC, 128)*RE7 + RE7[1]; Signal = EMA – AA*RE8; Plot1(Signal); Plot2(0); I translated like this for prt, can you please tell me if it is ok? AA= 0.1 CC = 1 - AA if barindex > 1 then EMA = AA*Close + CC*EMA[1] RE1 = CC*EMA + EMA[1] RE2 = EXP(2*LOG(CC))*RE1 + RE1[1] RE3 = EXP(4*LOG(CC))*RE2 + RE2[1] RE4 = EXP(8*LOG(CC))*RE3 + RE3[1] RE5 = EXP(16*LOG(CC))*RE4 + RE4[1] RE6 = EXP(32*LOG(CC))*RE5 + RE5[1] RE7 = EXP(64*LOG(CC))*RE6 + RE6[1] RE8 = EXP(128*LOG(CC))*RE7 + RE7[1] Signal = EMA - AA*RE8 endif return Signal

It’s suite, so it would work (As Jsmooth and so on) coef is good I will think about it but actually I don’t see what is wrong

ok, as promised, I found at least 1 strategy who works with the indicator under discussion. its on eurchf 30 min. Here is the code, I just started to work on that, so it is a bit rough. Nicolas, I attached a new version of the indicator as discussed, I added the nice graphical version provided by Ale, then mean, and bollinger band. Thanks Francesco

Thanks Francesco, but you should have used a longer period to compute the mean and its deviation IMO, I haven’t opened your code already but did you try to optimize these values?

i have used the 20 period for mean and stdev. the 2 that you see in the picture is how many standard deviations the indicator is taking to define the bollinger bar. yes in the strategy I have optimized the parameter number of stdev but not the period of the moving average

Just like an MACD, who cares? There is a “zero” level, but I understand your concern .. how to use it effectively? Maybe the answers are in the Ehlers’ interview?
Yes, It like a MACD with fast setting and smoothed. You can simple place REVERSE EMA with macd ( 9, 17, 4) together in subchart to compare. Nearly overlap in most of the time. When comparing with standard macd, you can take the Cross over as swing signal to do.

Hi,
I listen to the podcast on this one, (bettersystemtrader), and found it interesting. But they never talked about how to trade this indicator. I made a scanner for this one, looking for share that moves from negative to positive. But I can’t say that that gave me anything, very bad result trying to paper trade long in those scenarios…. :-/
Anyone here have an suggestions on how to trade this indicator?
