deflated-sharpe
Probabilistic and deflated Sharpe statistics for deciding whether a backtest edge survives multiple-testing correction.
Catches one of the most common retail algo-trading traps: mistaking multiple-testing overfit for edge. Dependency-free and extracted from live use.
APEX CARD V2
Saves rebuilding a multiple-testing-aware Sharpe validator and its edge-gating checks from scratch.
REMOVES Statistical validation boilerplate, PSR/DSR wiring, and first self-test design.RISK DATA-ONLY
Extracted from stillme OI-flow v2 validation work.Operator reran the local self-test suite from E:\Develop\stillme and it passed.Dependency-light statistics path with no trading authority.
