Put-heavy options flow
Put volume above 0.7× call volume on the session — hedging or fear running through today's options tape.
This is the traded-volume cousin of the open-interest PCR scans: open interest measures positions being held, volume measures what changed hands today. On NSE single stocks the flow skews heavily to calls — the median name trades roughly two calls for every put — so a session at 0.7 puts per call is a genuine tilt toward the downside, not neutrality. What volume cannot tell you is who: a put buyer hedging and a put writer harvesting premium print the same contract. Read it with the price — put-heavy flow in a falling stock is protection being bought, while in a rising one it is often writers funding the floor.
