Secondary momentum · 0–100
Rotation = current Momentum Score − Momentum Score five sessions ago.
Momentum is displayed as supporting context in the ranking and security detail; it does not determine the selected-horizon winner/loser order. The full-universe batch source supplies closes but not historical volume, so the 10% volume percentile is held at a neutral 50; full OHLCV is fetched when a security detail opens.
