--- Comment #4 from Anastasius Focht  ---
Hello folks,

confirming.

Stable download link to Zorro v2.09 (matching screenshot from comment #2) via
Internet Archive:

I've rephrased the title of the bug report as it was misleading. Wine doesn't
implement MFC at all which provides the 'COleDateTime' class (it could have
been interpreted as such).

Trace log shows the following OLE date/time APIs being used by the app (or
rather the MFC COleDateTime code the app is linked with):

* oleaut32.SystemTimeToVariantTime
* oleaut32.VariantTimeToSystemTime
* oleaut32.VarUdateFromDate

@jcl (comment #3)

> From comparing both logs, I suspect a difference of COleDateTime.GetDayOfWeek()

or GetHour() when the date is close to a day or hour boundary.

I presume you are one of the developers of this app?

It would definitely help to have a small test app that shows this behaviour or
alternatively reduce the simulation to the absolute minimum.

I've played a bit with the simulation parameters to reduce the amount of
data/smaller time series but I was only partially successful.

'/home/focht/.wine/drive_c/users/focht/Zorro/Strategy/Workshop4.c'

--- snip ---
// Trend Trading ///////////////////
#include <profile.c>

function run()
{
    EndDate = 2017; // fixed simulation period 
    Verbose = 2;
    set(LOGFILE|PLOTNOW); // log all trades

vars Prices = series(priceClose());
    vars Trends = series(LowPass(Prices,300));

Stop = 30*ATR(100);

vars MMI_Raw = series(MMI(Prices,300));
    vars MMI_Smooth = series(LowPass(MMI_Raw,300));

if(falling(MMI_Smooth)) 
    {
        if(valley(Trends))
            enterLong();
        else if(peak(Trends))
            enterShort();
    }

PlotWidth = 800;
    PlotHeight1 = 300;
    //setf(PlotMode,PL_FILE);
    //setf(PlotMode,PL_FILE);
    //plot("MMI_Raw",MMI_Raw,NEW,GREY);
    //plot("MMI_Smooth",MMI_Smooth,0,BLACK);
    //plotTradeProfile(-50); 
}

You have way more insight how adjust the parameters to reduce the amount of
output, specifically Lookback and Depth.
