BUY signals only during altcoin season — pooled across both modes (aggressive + conservative)
Multiple-testing threshold
▼
Testing several filters on the same data raises the chance that one looks good by luck. SR̂₀ = 0.226 is the Sharpe the best of 11 trials (no filter + every filter of this strategy) would reach by chance alone — computed from the spread of these trials' Sharpe values (extreme-value formula per Bailey & López de Prado 2014).
The filter passes when its Sharpe (-0.131) lies above SR̂₀. This is a threshold test, not a probability: a true Deflated Sharpe would need each run's period count, skew and kurtosis. All Sharpe values are annualized over 365 calendar days.
