Custom Criteria Editor

Hello all,

I’m unable to cut and paste code into the Custom Criteria Editor! Any ideas as to why?

Additionally, is there a resource library available with sample codes above and beyond what’s native within MC that I might try?

Thanks for the help.

is there a resource library available with sample codes above and beyond what’s native within MC that I might try?

There's a discussion here with several examples and more information.

But the Custom Criteria Editor is kind of the old way of defining a custom criteria, because now there's also the SetCustomFitnessValue keyword.

With `SetCustomFitnessValue()` there are a lot more options available. Plus you don't have to write JavaScript-like code but can simply use PowerLanguage in MultiCharts' regular editor.

JoshM,

Thanks for the input. I’ve tried using those, the built in Sharp Ratio, and it produces a division by zero error. This is attached to code that otherwise has traded without issue forever! I know I’m doing something wrong I just can’t figure out what that is!

It doesn't have to be your mistake! It might also be that the script has a wrong input or calculation that makes it try to divide by zero. The built-in `SharpRatio` function does seem to handle possible division by zero errors well by checking for that.

One option to easier find the problem is to use `SetCustomFitnessValue()` in a separate signal rather than in the main signal. That way when there's an error you "only" have to troubleshoot that specific signal that sets the custom criteria. That might make the task a little more manageable!
