How to Read the Chain
Use this market-close chain snapshot to compare liquidity, pricing, IV, and per-contract greeks across the active expiration.
How to scan it
Start with strike, bid/ask spread, open interest, and volume. Then use IV and greeks to decide whether a contract fits your directional, income, or volatility idea.
What matters first
Clean fills matter before a contract looks mathematically attractive. A thin market can erase the edge you think you found.
What can mislead you
Low premium, high IV, or one convenient delta do not make a trade by themselves. Check how far the strike sits from spot, expected move, and the event calendar.
Greeks are close-of-day estimates, and blank greek cells usually mean usable implied volatility was unavailable for that contract.
