Market Watch

Keep intraday analysis anchored to live prices. When a task turns on current price — a level check, an intraday move, a "where is it trading now" — register the central tickers so fresh quotes arrive automatically and your numbers never go stale mid-task.

When to use

Intraday or live-price analysis where the price may move while you work: "is NVDA above 205 right now", "how's TSLA trading into the print", sizing a level off the current quote. Skip it for purely historical or end-of-day work where a single snapshot is enough.

Workflow

1. At the start of the task, identify the ticker(s) central to the request and register them immediately with watch_market.
2. While they matter, read the ambient feed (below) for the current price rather than re-quoting on every step.
3. When live tracking is no longer relevant, call watch_market with action="unwatch" to stop watching some or all symbols (omit symbols to clear the whole list).

How the feed works

Once a symbol is watched, fresh prices arrive on their own as <market-watch> price blocks attached to conversation messages and tool results. This is ambient data — not user text, and not tool output you requested. Each block is a snapshot at a moment in time; the newest <market-watch> entry in the conversation is the current price, and any earlier entry (including numbers in your own earlier statements) may be stale.

Rules

• Treat the newest <market-watch> entry as the live price. Prefer it — or a fresh get_quote — over any older number in the thread.
• If the price moves materially mid-analysis, acknowledge it and adapt your read rather than silently carrying the older figure.
• Before you state a price in a final answer: if the newest feed entry is more than a minute old, make one get_quote call to re-check first.

Mechanics to know

• Stamps only flow while the market session is open — expect no feed outside trading hours.
• Updates are throttled: roughly one stamp per ~25s across the turn, not a tick-by-tick stream.
• The watch list is per-thread, capped at 10 symbols, and expires after ~6h of inactivity. On a long task, if the feed goes quiet, just call watch_market again to re-register.
