Use a input parameter from from strategy in Optimization fitnesses

[wagner4691]

How can I use a input parameter from from strategy in Optimization fitnesses? I would like to use “QTD_Max” in an Optimization Fitnesses calculation

[NinjaScriptProperty]
[Range(1, int.MaxValue)]
[Display(Name="QTD_Max", Order=2, GroupName="Parameters")]
public int QTD_Max
{ get; set; }

Hello wagner4691,

Thank you for your post.

You wouldn't be able to directly access the parameter from the Optimization Fitness script. You could try creating a public static variable in an addon. You could then assign the value of the parameter to it from your strategy, and access it from your Optimization Fitness. I will put together a test script and will reply back with that on Monday.

Thanks in advance; I look forward to assisting you further.

Hello wagner4691,

Thank you for your patience.

I've created three example scripts to show you how you could get this value in your optimization fitness script. One: a modified version of MySharedMethodsExample that creates a static int variable that may be accessed from any other script; two, a strategy that assigns a value to that variable called "TestSharedInt", and an optimization fitness script that just prints the current value of the variable when used while optimizing the TestSharedInt strategy called TestOptFitness.

If you import these, you can test this out to see it working by running an optimization on TestSharedInt and selecting the TestOptFitness Optimization Fitness and viewing the output in a NinjaScript Output window. You can use this same idea with your script to get your parameter from your Strategy in your own Optimization Fitness.

Please let us know if we may be of further assistance to you.
