This page now reads a local JSON quote feed instead of calling Yahoo directly from the browser. Search area remains a draft for later expansion.

Yahoo Connector Skeleton

Suggested first implementation structure for the prototype:
getQuoteData(ticker) -> returns { price, dayChangePct, volume, premarket } getIndexSnapshot([SPY, QQQ, DIA, IWM, VIX]) -> fills top cards getBasicOptionsChain(ticker, expiry) -> returns calls / puts with strike, bid, ask, volume, oi, iv normalizeOptionsData(sourceData) -> converts Yahoo shape into internal UI format renderOptionPairs(normalizedData) -> fills call / put cards + detail panel

Data Sources (Yahoo first)

Prices / ETFs
Yahoo Finance is now used server-side to generate a local quote snapshot JSON. Later swap to Futu OpenD / broker feed for stronger live monitoring.
Options chains
Yahoo Finance can cover basic options chain prototyping first. Later upgrade to Futu OpenD, Tradier, Polygon, or broker options APIs for deeper options monitoring.
AI / alerts layer
OpenClaw can summarize Yahoo-based prototype data first, then later post richer alerts once deeper options data is connected.

Yahoo Prototype Notes

In this version, the browser reads a local quotes.json file generated from Yahoo Finance data. This avoids direct browser-to-Yahoo fetch failures.

The current feed covers:

• SPY / QQQ / DIA / IWM / OPEN basic prices
• simple market snapshot
• basic options chain prototyping

Limitation: Yahoo is fine for a first prototype, but not ideal for serious long-term options flow monitoring or unusual activity scanning.

v6 Scope

v8 switches from direct browser Yahoo fetch to a local JSON feed model.

Next step:
• implement `getQuoteData()` and `getBasicOptionsChain()` using Yahoo-first logic
• normalize the payload into a stable internal format
• later swap Yahoo with Futu / Tradier / Polygon without redoing the UI
