Top Options Volume Chart

This tool surfaces the top traded options for a ticker by aggregating option chains from Yahoo Finance and ranking contracts by volume. On submit, the frontend calls a Next.js API that launches a Python worker using yfinance and pandas. The worker pulls all listed expirations for the symbol, fetches each option chain, tags calls/puts, and safely coerces fields to numerics. It filters out contracts with missing/zero volume or open interest, sorts by volume, and returns a compact JSON payload: contract label (expiration • strike • C/P), volume, open interest, and type. The UI then renders a stacked bar chart where call/put volumes are color-coded and open interest is shown alongside for context, letting users quickly spot the most active strikes/expiries and where liquidity is concentrated. The pipeline is stateless (base JSON over stdout), resilient to partial chain failures, and optimized for fast, explorable market scans.
