Yahoo Finance Alert Monitor ๐
Watch a list of tickers and get paid-for alerts only when something genuinely moves โ not a data dump on every run.
Most Yahoo Finance actors just hand you today's quote and stop there. This one remembers where each ticker was last time and only bills you when it moves a meaningful amount from that point, or breaks a 52-week high/low.
Why this exists
Every existing Yahoo Finance / TradingView-style Actor on the Store is a one-shot pull: run it, get today's numbers, done. None of them offer a durable monitor that only charges for a genuine, new price event.
How it works
- Give it a
monitorId, a list of tickers, and a % move threshold (default 5%). - Each run checks the current price against your last alert point for that ticker.
- You're billed once per genuinely new alert: the price moved โฅ your threshold since the last alert (in either direction), or the ticker crossed its 52-week high/low for the first time since the last time it was inside that range.
What you pay for
One event โ price-alert-delivered. Billed once per delivered alert. Checking a ticker that stayed within your threshold is free. Re-running the same monitor never re-bills an alert you already got.
Input
| Field | What it does |
|---|---|
monitorId | Names this monitor's durable history โ required. The % threshold is locked to this ID on first run: changing it later fails loudly instead of silently changing what counts as a new alert. |
tickers | 1โ50 Yahoo Finance symbols (e.g. AAPL, MSFT, BTC-USD). New tickers can be added later under the same monitorId. |
priceChangeThresholdPercent | How big a move triggers an alert (1โ50%, default 5%) |
notifyOn | new_alerts (default) fires the webhook only when paid alerts were delivered |
webhookUrl | HTTPS only; delivers a digest of paid alerts as JSON |
Output
- Dataset โ one row per delivered alert: ticker, alert type (
pct_up/pct_down/52w_high/52w_low), current price, the reference point or 52-week level it crossed, timestamp. - Run status โ clear reasons on bad input, a locked-threshold mismatch, or a run that ran out of time.
What this does NOT promise
Investment advice, predictions, or real-time data faster than Yahoo itself provides. Volume-spike alerts are not in v1 (the data needed for an honest baseline isn't available from this endpoint yet).
A note on the source
Data comes from Yahoo Finance's public chart endpoint via the same request pattern a logged-out browser makes โ no login, no account risk. Not an official API; the route could change at any time.
