Tight Range Contraction (TRC)
A shallow, tight sideways base after a prior advance — price range narrows sharply near the pivot.
Tight Range Contraction describes bases where the daily range compresses into a very narrow band (often under 8–10% total depth) after a meaningful prior run. Unlike deep VCPs, TRC bases are shallow but extremely tight.
Swing Edge documents TRC in its pattern guide at /patterns/tight-range-contraction and uses tightness metrics in pre-breakout scoring.
