Summary

This wraps the full Yahoo Finance API and adds a local SQLite layer for portfolio tracking, covered call screening, and fundamentals queries that persist across sessions. You get cost-basis-aware performance reports, yield-on-cost dividend tracking, and a screener you can run offline against synced data. The options chain filters by moneyness and DTE, the digest command bundles overnight news with movers and earnings for your watchlist, and there's a Chrome cookie fallback when Yahoo rate-limits your IP. Reach for this when you need market data that remembers your positions or when you want agent-native compute on top of raw endpoints instead of stitching together multiple API calls.

longbridge-security-list

longbridge/skills

US overnight-eligible securities directory and HK broker participant directory via Longbridge Securities. `security-list` covers the US overnight-trading catalog only (this is the only category exposed through this endpoint). `participants` is the HK broker_id ↔ name dictionary. For non-US listed-stock lookups, route the user to `longbridge-quote` for individual symbol queries. Triggers: "美股 listed", "美股 overnight", "经纪商 ID", "broker_id", "港股经纪商", "港股經紀商", "經紀商 ID", "list of US stocks", "overnight tradable", "broker directory", "participant lookup".
