Bullish OBV (volume-flow) divergence

The result

Code: research/obv_divergence.py Report: research/obv_divergence_report.json (n=9,013)

Third independent divergence mechanism — same template as RSI/MACD but on cumulative signed volume. Lower n than MACD div (more selective) but similar edge magnitudes:

Bucket n 20d edge 40d edge
obv_div all 9,013 +4.8 % +4.5 %
obv_div dd ≤ -30% 1,586 +8.1 % +9.0 %
obv_div OOS 2020+ dd ≤ -30% 1,065 +8.7 % +9.9 %

Three independent divergence detectors (RSI / MACD / OBV) all producing +9-13 % edge at 40 d in drawdown OOS, with 74-80 % hit rates, is strong triangulation. Divergence as a signal family is robust.
