Monitoring CENX open interest helps you see where real money is positioned on Century Aluminum Co's options and which strikes are attracting the most commitment from traders. Century Aluminum Co's open interest reflects the total number of outstanding contracts that have not been closed or exercised, making it a powerful gauge of liquidity, conviction, and potential support and resistance zones. Use our scanner to monitor CENX options open interest in real time and find the strikes that matter.

Open interest is distinct from volume: volume counts how many contracts are traded in a session, while open interest counts how many remain open at the end of the day. Rising CENX options open interest alongside rising volume suggests new positions are being built, while falling open interest signals positions are being closed. Heavy open interest at specific strikes often acts as a magnet near expiration and can hint at where dealers and large traders expect Century Aluminum Co to settle.

Century Aluminum Company, together with its subsidiaries, produces standard-grade and value-added primary aluminum products in the United States and Iceland. It also owns and operates a carbon anode production facility in the Netherlands. The company was incorporated in 1981 and is headquartered in Chicago, Illinois.

Pin risk into expiration, dealer positioning, liquidity checks for large orders — all of it starts with knowing where CENX open interest is concentrated. Our scanner maps Century Aluminum Co's open interest across every strike and expiry, flags unusual buildups, and lets you drill into the contracts that institutional money is actually holding.
