Options Chain
Options Chain shows recorded calls and puts for a company with options coverage. It is available to Free, Pro Lite, and Pro users.
Before you begin
Open a company page with options coverage.
Quickstart
- Expand Options Chain on the company page.
- Check Last updated and choose an Expiration.
- Select a call or put to inspect that contract's history.
What it shows
Calls appear on one side, puts on the other, with the strike between them. The ATM marker identifies the displayed strike nearest the stock price.
Outputs and how to read them
Chain columns
| Column | Meaning |
|---|---|
| Last | The recorded last traded option price. |
| Bid/Ask | The recorded buying and selling quotes. |
| Vol | Trading volume in the observation. |
| OI | Open interest, the number of outstanding contracts. |
| IV | Implied volatility, a measure derived from option pricing. |
| Delta | Estimated sensitivity to a change in the underlying stock price. |
The compact mobile view shows fewer details at once. Open a contract for its history. Missing values or a missing call or put are unavailable observations, not zero-price offers.

Data and timing
The chain and contract charts use recorded observations. Check their timestamps; they are not executable quotes. A contract's history may cover only part of its life.
Limitations and disclosures
Greeks are estimates and can change sharply. Wide spreads and low activity can make a displayed last price unrepresentative. The chain does not place an options trade.
