Hi there, yesterday I came across this website https://www.quantopian.com/posts/predicting-future-returns-of-trading-algorithms-bayesian-cone

We all no that no EAs can perform well forever, however we cannot distinguish between a losing period or actually the market condition has changed, and thus we can no longer use that EA.

They use something called 'bayesian cone' to check whether the EAs work as expected (in the cone or not), and when it not we can remove it from real live trading to prevent further drawdown.

I believe it would be awesome to have this feature in EA Studio, so at least we have something to help us be confident when EA is in losing period, and also know when to get rid of one.
