Open Interest vs Volume
The Open Interest vs Volume guide (SKU SML-OPTIONS-009, $19 one-time) shows how to use volume and open interest without inferring trader identity, intent or direction the data cannot support: volume is today’s activity, open interest is outstanding contracts — with OCC, Cboe and FINRA source references and no outcome promises.

THE OUTCOME
How do you use volume and open interest without inferring trader identity or intent?
Volume counts today’s activity and open interest counts outstanding contracts — and neither establishes beneficial owner or trade motive, so label identity and intent as unknown.
Use this guide to: Distinguish option trading volume from open interest and check liquidity without assuming direction.
CORE MODEL
What will you learn from this guide?
Four ideas before action: volume is today’s activity, open interest is outstanding contracts, the comparison is contextual, and execution data still needs context.
Open interest is outstanding
It is generally updated after clearing and does not show only new bullish positions.
The comparison is contextual
Volume above prior open interest can flag activity but not whether trades opened, closed or hedged.
Execution data still needs context
Strike, expiration, price, spread, stock move and catalysts all matter.
ACTION CHECKLIST
What concepts and decision checks does the guide cover?
A six-step review process: confirm data timestamp, compare the same contract, check prior-day open interest, review execution near bid, ask or midpoint, look for multi-leg relationships, and label identity and intent as unknown.

- Compare the same contract
