Topic: Question about R-Squared

Dear Mr. Popov,

The addition of R-Squared is a great improvement. However I have noticed many times weird (non linear) balance lines with very high r-squared values.

The following image illustrates it very well. The below strategy is clearly more linear than the one above it and has a lower r-squared value

Is this a normal behavior? Is there a way to make EAS filter-out the strategies that have such stepped appearance?

Thank you in advance for your help.

Best regards,

mw

Re: Question about R-Squared

Yes, I also think there is still something wrong with the R-Squared implementation in EA Studio. Especially strategies with very long duration trades seem to get a much higher R-Squared value, even if their curves look completely "bad" and the first one in your example surely should not have a higher R-Squared than the second one. I am sure the R-Squared formula itself in EA Studio is fine, but that there is a bug of how EA Studio counts / "forwards" the data points to the R-Squared formula.

Mr. Popov?

Re: Question about R-Squared

I  fixed some issues with the formula and it covers better some special cases now.

Here is an example of comparison of the EA Studio calculations and an online statistics calculator.
