Academy->How to Read an Option Chain
An option chain is where every options trade begins. When you first open one, it can look overwhelming. Hundreds of strike prices, multiple expiration dates, and rows of numbers all compete for your attention. The good news is that you don't need to understand everything at once. Once you know what each column represents, the option chain becomes much easier to read.
An option chain is a table that lists every available option contract for a stock.
Each row represents a different strike price.
The table is divided into Calls on one side and Puts on the other.
Each contract also belongs to a specific expiration date.
Although every trading platform looks a little different, most option chains include the same information.
- Strike Price
- Bid Price
- Ask Price
- Last Price
- Volume
- Open Interest
- Implied Volatility
Each value tells you something different about the option contract.
When you're starting out, don't worry about every column.
Focus on understanding these first:
- Strike Price – The price written into the option contract.
- Premium – What the option is currently worth.
- Bid and Ask – The current buying and selling prices.
- Open Interest – The number of active contracts.
- Volume – How many contracts have traded today.
Once you understand these, the rest of the option chain becomes much easier to follow.
A typical option chain displays calls, puts, strike prices, premiums, volume, open interest, and implied volatility.
Every options decision starts here. Whether you're selling a cash-secured put, choosing a covered call, or comparing different strike prices, the option chain contains the information you need. Learning how to read it is one of the most valuable skills an options trader can develop.
