How the score works
Everything is measured against each stock’s own norm, so large caps are not favoured for liquidity: volume so far vs its 20-day average at the same time of day (35 pts) · price move and gap in standard deviations plus day range vs normal (45 pts) · earnings and fresh news (20 pts).
