Binance WebSocket BTC Price Alert

Binance WebSocket BTC Price Alert

Connect to Binance's public market data WebSocket and react to live BTC/USDT price movements in real time — no API key or account needed for public ticker streams.

What this workflow does

1. WebSocket Trigger subscribes to the Binance BTC/USDT 24-hour ticker stream
2. Condition compares the current last price against a configurable threshold
3. On breach → Set formats the alert payload with symbol, price, and percent change
4. Output returns the structured alert ready for downstream use (Slack, Telegram, email, etc.)
5. Non-breach ticks fall through to a lightweight Output for run tracking

Use cases

• Personal price alert bot that fires when BTC crosses a target
• Automated DCA (dollar-cost averaging) entry signal
• Portfolio rebalancing trigger on price breach
• Trading journal or analytics event source
• Webhook bridge to Slack, Telegram, or a dashboard

Setup

The Binance ticker WebSocket (wss://stream.binance.com:9443/ws/btcusdt@ticker) is public and unauthenticated — no credential is needed. Change the coin pair by swapping btcusdt in the URL for any listed pair (e.g. ethusdt, solusdt, bnbusdt).

Adjust the threshold in the Condition node ($int($BinanceFeed.message.data.c.substring(0,5)) > $int(78500)) to your target price. The field c is the last traded price as a string (e.g. "78523.45") — substring(0,5) strips the decimal part and $int() casts both sides before comparing.

Key ticker fields:

Tip: For multiple pairs at once, use the combined stream URL: wss://stream.binance.com:9443/stream?streams=btcusdt@ticker/ethusdt@ticker Each message will include a stream key identifying the pair.
