It sounds as if you just hit a combined bad patch which is probably more likely when you are running several mini systems within a portfolio. When you posted the SR was below your historical average, but 300 odd selections simply isn’t sufficient to iron out the highs and lows of a 20% SR. Statistics and probability can be strange highlighted by the fact that it’s quite common to hit a run of 6/7 heads or tails when tossing a coin (a 50% probability or SR), but toss that coin 100 times and you are fairly certain to have a split between 48-52 of heads and tails. Be a devil and post again with the expectation that the results simply won’t be linear over a short period.
