    What would be a good filter for a Mean-Reverting system?

    Backtested. Last twenty years of data. I am not trading markets in the US. The problem with becoming a billionaire is that, if I get 12 consecutive losses, I would blow my account at some point in time. I tested on around 2500 trades.

    What would be a good filter for a Mean-Reverting system?

    The average win/loss ratio is around 1:1. The strategy is fine the way it is, it is just that losses come in clusters. I am also running a trend-following system, so I don't mind if I get lesser trades in this system so that losses don't come in clusters.

    What would be a good filter for a Mean-Reverting system?

    I am in the process of making a mean-reversion trading strategy. The current winning percentage I am getting is 67. However, the strategy tends to incur many, many consecutive losses in periods of sustained downtrend. For instance, during the 2008 financial crisis, it would probably have 20-30...

    Note that I am not optimizing my strategy over all my stock universe. I just look at a couple of stocks, see what feels correct, and then apply that strategy on all the stocks. I don't test and retest on all the stocks.

    How to know whether I am overfitting?
