An Option chain is a structured table displaying all available strike prices for a chosen underlying and expiry, typically with Call (CE) information on one side and Put (PE) information on the other, organized around a central strike price column. Standard columns include premium, bid/ask, volume, Open Interest, and often Implied Volatility and Greeks.
