Run the pre-move OI accumulation recipe
A paid Cookbook of near-dated calls whose open interest accumulated from a low base, traced contract by contract. The pattern is descriptive. It does not name a trader or prove a future move.
Official template: Pre-Move Positioning — OI Accumulation · Updated 2026-09-11
The job
See whether OI actually built after loud prints, instead of trusting a one-session sweep.
What this recipe computes
- Near-dated calls whose open interest accumulated from a low base across sessions.
- A Historical Volume / OI ledger per contract (volume followed by OI change).
What it does not claim
- OI chronology is not opening vs closing proof, ownership, or private information.
- It does not identify a whale or forecast the next move.
- It is T+1 confirmation of positioning, not a live 0DTE inventory.
How to read it
Step 1
Run the accumulation recipe
Open Pre-Move Positioning — OI Accumulation in Cookbooks.
Step 2
Read volume then OI change
A print that does not show up as OI the next session is a different story from a contract that kept building.
Step 3
Do not upgrade the chronology
Treat the ledger as descriptive. Motive, identity, and “will it run” are outside the recipe.
Frequently asked questions
- Does rising OI mean someone is still long?
- No. Open interest is a count of open contracts, not a named book. The recipe traces chronology. It does not prove who holds the risk.
- Can I use this as a lottery scanner?
- It lists contracts with OI build from a low base. That is not a cheap-OTM lottery product and it does not claim those contracts will pay.
Related glossary
- Open interest (OI)Open interest is how many options contracts remain open. Unlike volume, it does not reset each morning and usually updates after the session.
- Volume / open interest (Vol/OI)Vol/OI is today’s volume divided by open interest. High ratios mean today’s trading is large versus the standing book.
- Unusual options activity (UOA)UOA flags contracts or underlyings trading far above recent norms in volume, size, or premium. It is an attention screen, not a directional signal.
- 0DTE (zero days to expiration)0DTE options expire the same trading day. Gamma and theta move fastest near the money on that clock.

- Options Flow for Swing TradersSwing traders care about positioning that can last more than a day: unusual flow, OI confirmation, and walls for multi-day levels.
- Unusual Options Activity for EarningsEarnings compress time: IV is rich, strikes get loud, and the wrong filter set gets expensive. Rank unusual activity, bound DTE to the event, and plan for IV crush as well as direction.
