Optimization Error while displaying values

[Waxavi]

I'm having an issue here where the optimization results differ from the top window to the bottom, as you can see, total net profit is $0.00 above and $135.21 below.

I'm wondering how can I troubleshoot this issue, didn't find anything relevant while googling, would appreciate your support.

Hello Waxavi,

May I confirm you are able to reproduce this using the latest release of NinjaTrader 8.1.1.3?

Are you able to reproduce this behavior using the SampleMACrossover included with NinjaTrader while using 8.1.1.3?

Hello ChelseaB,

I have currently the 8.0.27.1 64-bit version

This behavior doesn't happen using SampleSMACrossover

I will try again with the latest version and let you know also

Thank you

Hello ChelseaB, would it be possible to assist me without upgrading to the last version just yet?

I can confirm the same error on the most current ( downloaded today) version of ninja trader. I work with Waxavi. This is across Multiple computers

Hello Waxavi,

If the behavior does not occur with the SampleMACrossover this would imply there is an issue in the code of the script.

If you comment out all code and use a simple entry and stop, does the behavior still occur?

kpoulis,

Hello ChelseaB,

The code base is fairly long, so it would take me a while to pinpoint the main cause, I'll get back to you as soon as possible. Having said this, I think it doesn't make sense the strategy could affect the optimization layout this way.

Thank you!

Do you think we can get a resolution

Waxavi The image you posted initially shows all entries in the top of the display being the same; namely, looking as if they are all "zero" or "initial values". Do the details in the bottom section also vary for all the other entries above?

NinjaTrader_ChelseaB When you say "this would imply there is an issue in the code of the script", please provide more detail to substantiate this. Do you have an example that can produce that effect? Can you give examples of the types of code that would do that?

Without knowledge of the "under the hood" code in the platform, it is hard to say what exactly is happening, but it seems fair to say that it would seem "extremely unlikely" (though perhaps not impossible) that strategy code could cause platform code to be so completely at odds and inconsistent in itself.

Thanks.

Hello jeronymite,

I'm still trying to pinpoint the cause of this issue, but indeed I don't think the code should hinder the proper behavior of optimization results, and if it does, the log should tell me something.

Hello jeronymite,

If the version is the latest release 8.1.1.3 and the SampleMACrossover is not able to reproduce, that would imply something in the script is triggering the behavior.

It would be necessary to reduce and find the specific code causing the issue. A simple test would be to just comment out all the logic and place a simple entry and exit and make sure that works first.

[jeronymite]

NinjaTrader_ChelseaB Yes, that's logical. But the fact that a script can cause this behaviour at all implies a design flaw in the underlying platform code. It would be good to know what specific script code manifests the behaviour, but the fact remains that the behaviour should not occur, regardless of what's in a script, and it represents an as-yet-unknown bug in the platform.

Thanks.

Hello jeronymite,

Not all C# is valid logic.

Try adding the following to a script:

while (true) Print("Hello");

In one line you will have broken NinjaTrader. There would nothing the developers can do to stop bad logic from being coded into a script.

Hello ChelseaB,

I can certify this issue disappears if I set IsInstantiatedOnEachOptimization to true, therefore it might be a private variable in memory or something similar.

Still looking to narrow it down.

Hello Waxavi,

When using IsInstantiatedOnEachOptimization as false, may I confirm that all variables are being instantiated / reset in State.DataLoaded?
