THE OUTCOME
Use volume and open interest without inferring trader identity, intent or direction that the data cannot establish.
Primary search intent: open interest vs volume
CORE MODEL
Four ideas before action.
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
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
- Label identity and intent as unknown
PRIMARY SOURCES
