    So, Scott, you ready to throw in the towel? This is exacly what you coded, and, you know what, it's crap. So quit. We may have established it's profitable, but it doesn't make much for the risk you're taking.
     
  2. Here's the Hershey 5.0 script, everything is the same, BUT the entry logic.
    for Bar := 5 to BarCount - 1 do
    begin

    var SMADiff : float =(SMA( bar, #close , 20 ) - SMA( bar - 1, #close, 20 ));
    var MACDday : integer = MACDExSeries( #Close, val1, val2 );
    if lastbar(bar) then begin
    lbar:=bar;
    end;
    if (bar>lbar+2) and (gettime(bar)<1600) and (@#Volume[bar]>20000) then begin
    if not (lastpositionactive) and (crossovervalue(bar,HersheyStochK,50)) then begin
    buyatmarket(Bar+1,'Jacks friend scott d says to buy here');
    end;
    if not (lastpositionactive) and (crossundervalue(Bar,HersheyStochK,50)) then begin
    shortatmarket(Bar+1,'Jacks friend scott d says to sellshort here');
    end;
    if (positionlong(lastposition)) and (@HersheyStochK[bar]<@HersheyStochD[bar]) and (crossundervalue(Bar,HersheyStochK,80)) then begin
    sellatmarket(Bar+1,LastPosition,'');
    end;
    if (positionshort(lastposition)) and (@HersheyStochK[bar]>@HersheyStochD[bar]) and (crossovervalue(Bar,HersheyStochK,20)) then begin
    coveratmarket(Bar+1,lastposition,'');
    end;
    if (positionlong(lastposition)) and (abs(@HersheyStochD[bar]-SMA(Bar,HersheyStochD,6))<1.4) then begin sellatmarket(Bar+1,LastPosition,''); end;
    if (positionshort(lastposition)) and (abs(@HersheyStochD[bar]-SMA(Bar,HersheyStochD,6))<1.4) then begin coveratmarket(Bar+1,LastPosition,''); end;

    end;
    end;
     
  3. Apparently Jack believes this work is something worthy of such a prize, but I doubt it anyway. As you can see by the results in WL.

  6. In fact, this long portion looks like where the losing side is.
     
  7. Stops?
     
  8. Here's that farce of a system known as the Jack Hershey method. Start from page 1. Apparently they don't like experienced developers analyzing their crap for systems.
     
  9. Not sure why this thread got no attention, because it's a perfect WL replica of the tradestation program that Scottd AKA Jack Hershey created in their thread.

    What does it show?

    Jack's system may be profitable, but it's not worth it on a risk adjusted basis.

    The entry and exit logic is identical, making this a valid backtest. The whole program is everything at wl4.wealth-lab.com in Hershey 5.0 script, save for the entry logic, which was modified for the script that wanted to use 5 minute ES bars.

    What's the verdict?

    His system is crap, and sucks on a risk adjusted basis. With a profit factor of about 1.3, no one should trade it IMO.
     
  10. This is all at 10% of equity using ES contracts approximated with an SPX chart.
