Also check on my page have you been running the same version of Zorro in all the same periods. From what I understand, all Z strategies are reoptimized for every release and I upgrade often & fast. If we were running different versions in the past, I think the results could differ wildly.

At first I thought I would run only stable versions, and after they've been proved stable. But due to lots of initial instability I changed my mind and I now run each and every release, beta or not, I don't mind. It's all paper money, anyway.
