Hi uwescheffold,

There is no built in feature for this at the moment.

you can save individual pass parameters in an external file on your computer. Does that help?

No,sorry that does not help. Imagine there are 1050 results, to say save the parameters one after the other is - sadistic!

And what I need to analyse is the result of the optimisation and the parameters. The parameters alone are usless, since you have to run the backtest again to gets reults.

But anyway, I can't understand why it takes so long to inplement such an easy but neccessary function!

An a software developer I know that the solution would take only short time, one hour or so.

All you have to do is:

1.) apply save/load button to the panel.

2.) OnKlick, open File dialog.

3.) If successful save/load the tabledata in a xml, csv  or whatever file. Methods for that are readyto use in C#.

Alll of thois is realy simple and as it is not done for the last 4 jears, I assume that ther are no developers available? 

And consequently, does it make sense to use a system which can't be adapted to actual and future needs?

Hi uwescheffold,

What duketv is implying is that you can write this code in your cBot e.g. in OnStop() function. If it is a one hour job as you say, then it should not be so hard.

Sorry for replaying again. But saving parameters in OnStop means that you have access to the fitness-result-values in OnStop.

But that is not the case - sorry. What is needed is a parameter that contains the optimization result for the current run.

You can see that in the "protected virtual double GetFitness(GetFitnessArgs args)". In other words, OnStop would need access to the GetFittnessArgs-structure.

Would you point out a way to da that?

Hi uwescheffold,

OnStop()  was just an example. If you need access to GetFitnessArgs then you can do the export inside the GetFitness() method.

Did you know that the call of GetFitness only happens when the "optimisation criteria - custom" radiobtn is checked? But then you have to provide you own optimisation algo also. Do you realy know how your system is working?

Hi uwescheffold,

Yes I know but I do not understand what is the point of your comment. I am explaining to you the possible ways to do what you are looking for.

Use this every time PositionsOnClosed is called:

private double peak;
private List<double> drawdown = new List<double>();

private double CalcMaxDrawDown()
{
    peak = Math.Max(peak, Account.Balance);

    drawdown.Add((peak - Account.Balance) / peak * 100);
    drawdown.Sort();

    var maxDrawdown = drawdown[drawdown.Count - 1];

    return maxDrawdown;
}
