OPTIONS RESEARCH · THE METHODOLOGY
From unusual activity
to an informed setup.
Understand the clues. Compare the contracts. Model the outcome.
01 · READ THE ACTIVITY
What is the options activity telling you?
Volume counts contracts traded during a session. Open interest counts outstanding contracts after clearing. They measure different things: heavy trading can include repeated turnover and closing transactions, so volume does not translate directly into new positions.
Start with the ticker, contract type, strike, expiration and data date. Compare absolute volume with open interest and other contracts in the same chain. A high volume/OI ratio can flag activity to investigate; it cannot establish that the activity is unusual relative to history when no historical baseline is available.
02 · COMPARE THE CONTRACTS
Which contracts deserve a closer look?
Compare available volume and open interest across strikes and expirations. Check whether the expiration fits the event or time horizon you are researching. Monthly expirations are a useful starting point, but a date alone does not guarantee liquidity.
Higher participation can help build a shortlist. Before trading, check current bid and ask prices, quoted size and execution conditions with your broker. Volume and open interest cannot guarantee a fill or a tight spread.
Where implied volatility is available, compare similar contracts and note the data date. Missing IV is unknown, not zero. Cached snapshots describe the available contracts at that time, not a live executable quote.
Compare strikes and expirations →03 · MODEL THE OUTCOME
Turn an options idea into a strategy.
Choose an outlook and time horizon, then compare structures using editable premiums. A long option and a spread can express a similar view while having different costs, breakevens and payoff limits. Review every leg, quantity and contract multiplier.
Use the calculator to compare expiration profit or loss for a fall, a flat market and a rise in the stock. For example, a standard long call with a $100 strike and $5 premium has a $105 expiration breakeven and $500 premium at risk per 100-share contract, before fees. This is an illustration, not a trade recommendation.
