Data Source

Google Finance (browser_use navigate + get_text) — no API needed, no login, returns structured data.

Query Flow

Step 0: Set Desktop Viewport

browser_use set_viewport viewport_width: 1280 viewport_height: 800

Google Finance differentiates desktop/mobile mainly by viewport width. Setting a wide enough viewport gets complete data. This method is compatible across Android/iOS, not affected by UA enumeration differences.

Step 1: Three Major Indices (parallel, up to 3 tabs at once)

First open S&P 500 with default tab 0:

browser_use navigate https://www.google.com/finance/quote/.INX:INDEXSP?hl=en
browser_use get_text

Then create two new tabs for Dow Jones and Nasdaq:

browser_use new_tab
browser_use navigate https://www.google.com/finance/quote/.DJI:INDEXDJX?hl=en
browser_use get_text

browser_use new_tab
browser_use navigate https://www.google.com/finance/quote/.IXIC:INDEXNASDAQ?hl=en
browser_use get_text

Use get_text for each tab. Extract key fields: current price, change points, change %, open/high/low, previous close.

Step 2: VIX Fear Index (navigate within existing tab, no new tab)

browser_use navigate https://www.google.com/finance/quote/VIX:INDEXCBOE?hl=en
browser_use get_text

Key fields: current price, change %, previous close, 52-week high/low. VIX Alert Thresholds: <15 Complacent / 15-20 Normal / 20-25 Vigilant / 25+ Panic. Core assessment: VIX absolute value + daily change direction (mild VIX rise from individual stock events like Broadcom vs systemic panic-driven VIX surge)

Step 3: Magnificent 7 (rotate through existing 3 tabs, no new tabs)

No 4th tab for VIX — first navigate to NVDA in default/newest tab, use get_text, then jump to next stock in same tab.

Read order: NVDA → AAPL → MSFT → GOOGL → AMZN → META → TSLA After each stock, navigate to the next stock's URL, use get_text each time. If checking AVGO or other hot stocks, place after TSLA. Extract per stock: price, change %, change points, previous close, intraday high/low, market cap.

Step 4: 0DTE Gamma Status (optional, query when user requests or market fluctuates abnormally)

First close a finished tab to free up space (e.g. close VIX or the earliest index tab), then open new tab:

browser_use close_tab
browser_use new_tab
browser_use navigate https://www.google.com/search?q=SPX+gamma+exposure+today+dealer+position&hl=en
browser_use get_text

Extract Gamma status summary from AI Overview, focus on:

• Gamma Flip level: At what SPX level gamma flips from positive to negative
• Current SPX distance to Flip (e.g. current 7,583, Flip at 7,550, difference 33 pts = 0.4%)
• Dealer positioning: positive gamma (stable) or negative gamma (amplifies volatility)

GEX Risk Assessment Criteria:

Status	Description	Risk
Positive Gamma	Market makers follow trend, buy dips sell rallies	Market stable, volatility suppressed
Near flip (0-1%)	Golden line, critical	One surprise can trigger Gamma squeeze
Negative Gamma	Market makers chase gains sell losses	Volatility self-amplifies, corrections can become crashes

Step 5: Synthesize Output

Notes

• US stock trading hours: ET 9:30-16:00 (daylight saving = Beijing 21:30-4:00; winter = 22:30-5:00)
• Pre-market/post-market data should be timestamped, note comparison with A-share trading hours
• Google Finance displays ET time UTC-4 (daylight saving) or UTC-5 (winter)
• Fund/ETF net value lags by one day, annotate "previous trading day net value" when querying
• VIX futures backwardation is the strongest systemic risk warning signal; push this signal to memory and alert user when it occurs
