Volume = today's trades; OI = open contracts. Rising volume + rising OI = new money (conviction). Rising volume + falling OI = exiting (capitulation). Feature: vol_oi_ratio = volume / max(OI,1). The chain shows where conviction builds; the model weights vol_oi_ratio against pcr and oi_buildup. A strike with high vol_oi_ratio and bullish OI = genuine interest. Ignore low-volume noise strikes. Volume confirms or denies what OI implies -- read both.
