What Is an Options Chain?
An options chain, often referred to as an options matrix, provides a detailed listing of all available options contracts for a specific security. This includes comprehensive data on puts, calls, expirations, strike prices, trading volumes, and pricing information for a particular underlying asset during a defined maturity period. Typically, the chain is segmented by expiration dates and separated into calls and puts sections.
Key Features of Options Chains:
- Options chains are tables showcasing options quotes for an underlying security.
- Continuous updates provide real-time details on the last price, trading volume, and the best bid and offer for calls and puts, organized by expiration dates.
- Contains strike prices, defining the stock price activated if the option is exercised.
Decoding Options Chains
For retail investors, options chains offer a comprehensible format to present intricate trading information. The quotes are systematically listed, allowing traders to easily identify an option premium by corresponding maturity dates and strike prices. Bid-ask quotes or mid-quotes are often displayed within these chains.
Most online brokers and trading platforms present options quotes through an options chain with real-time or delayed data. This display facilitates quick scans of trading activity, open interest, and price changes, enabling traders to pinpoint the options necessary for their specific strategies.
Navigating Options Chain Matrix
Traders can swiftly access an asset’s trading activity, frequency, volume, and interest by strike price and maturity months. Data can be sorted by expiration dates from the nearest to the furthest term and refined by strike prices from lowest to highest.
Understanding Key Metrics in Option Chains
Four critical columns help traders evaluate current market conditions:
- Last Price: Reflects the latest trade price reported.
- Net Change: Indicates the price variance direction (up, down, or flat) from the previous trade for the underlying asset.
- Bid: Shows what a trader might expect to receive when selling the option at the current timeframe.
- Ask: Displays what a trader might pay to purchase the option at the moment.

Beyond these key columns, additional data on market size for a given option and trader commitment at each price level is available. This includes:
- Trading Volume: Represents the number of contracts traded within a day, offering insights into market liquidity for any given option.
- Open Interest: Measures total outstanding options on each strike and maturity, providing a gauge of market activity scale.
Keep in mind that open interest fluctuates intraday, and market makers report this information at the end of each trading day, making the option chain matrix particularly beneficial for planning trades on the next trading day.
