EntropyCore Pro condenses directional conviction into a single signed Bias Persistence Index, from −100 to +100, where positive shows buyers organising and negative shows sellers in control. The BPI combines a position component, measuring price against a Hull moving-average centerline in ATR units, with a persistence component counting how consistently recent closes lean one way. Entry-versus-maintain hysteresis and a flip cooldown keep the read stable, recolouring every candle by its bias for a continuous map of directional order.
