Option Chain
An Option Chain is the full table of available calls and puts across every strike and expiry, with their prices, OI, volume, and Greeks.
What an Option Chain Means
An Option Chain is the complete listing of all option contracts for an underlying, laid out as a table of strikes with calls on one side and puts on the other. Each row is a strike; columns show the last traded price (premium), bid and ask, open interest, change in OI, volume, and implied volatility. It is the single most important screen in options trading.
Reading the chain top to bottom shows the entire landscape — where premium is rich, where positioning is concentrated, and where the market expects support and resistance.
How to Read the Chain
Key signals come from the chain: the strikes with the highest call and put OI hint at resistance and support; OI change reveals fresh buildup; the bid-ask spread shows liquidity; and per-strike IV exposes the volatility skew. The ATM strike is the pivot — moneyness flips around it. Spread strategies are constructed directly by selecting strikes off the chain.
