Option Chain

Pulls option chain data from Yahoo Finance with all the standard fields you'd expect: strikes, bid/ask spreads, volume, open interest, and implied volatility for both calls and puts. You run it twice, first to see available expiration dates, then to fetch the actual chain for whichever date you care about. The output comes back as JSON with separate arrays for calls and puts, plus the underlying price for reference. It timestamps everything in New York time, which matters for options trading. Useful when you need to quickly scan the chain without opening a browser or want to feed the data into another script.
