Binance Alpha New Coin Launch Monitor

A real-time cryptocurrency listing monitor based on the Binance WebSocket API. It tracks the !miniTicker@arr stream to instantly detect and alert you when new trading pairs are listed.

How It Works

1. WebSocket Connection - Connects to the Binance streaming API (!miniTicker@arr).
2. Symbol Detection - Maintains a known_symbols set to identify newly appearing trading pairs.
3. Price Validation - Verifies via REST API that the new pair has a valid opening price.
4. Real-time Alerts - Outputs new coin listing information immediately.

Features

• ⚡ Real-time Detection - WebSocket streaming data with millisecond latency.
• 🎯 Accurate Filtering - Automatically filters out system symbols and invalid data.
• ✅ Price Confirmation - Dual verification ensures the pair is actually open for trading.
• 💾 State Persistence - Saves known pairs and historical alert records.
• 🔄 Auto-Reconnect - Automatically reconnects on drops to ensure uninterrupted monitoring.

Technical Details

WebSocket Data Source

Endpoint: wss://stream.binance.com:9443/ws/!miniTicker@arr

Data Format:

[
  {
    "e": "24hrMiniTicker",
    "E": 1234567890123,
    "s": "BTCUSDT",
    "c": "43250.50",
    "o": "43100.00",
    "h": "43500.00",
    "l": "42800.00",
    "v": "15234.56",
    "q": "658923456.78"
  }
]

Field Descriptions:

• s - Symbol (Trading Pair)
• c - Latest Price
• o - Open Price
• h - High Price
• l - Low Price
• v - Base Volume
• q - Quote Volume

Detection Logic

1. Receives all pair data from the !miniTicker@arr stream.
2. Extracts the s (symbol) field from each packet.
3. Checks if the symbol exists in the known_symbols set.
4. If not, verifies price validity via REST API.
5. Once confirmed, triggers an alert and adds the symbol to known_symbols.

Price Verification

Double-checks via Binance REST API:

GET /api/v3/ticker/price?symbol=XXX

Ensures the trading pair has a valid opening price (price > 0).

Configuration Files

State files are stored at: ~/.config/alpha/

• known_symbols.json - Set of currently known trading pairs.
• alerts_history.json - Historical alert records (last 100).

Command Reference

Environment

• Python 3.7+
• Internet connection (access to Binance)
• No API Key required (uses public WebSocket streams)

Use Cases

Scenario 1: First to spot new listings

# Keep monitor running
python3 scripts/alpha.py monitor

# Get immediate terminal alerts when a new coin is listed

Scenario 2: Tracking recent listings

# Review recently discovered coins
python3 scripts/alpha.py history --limit 10

Scenario 3: Periodic resets

# Reset weekly to rebuild the baseline
python3 scripts/alpha.py reset

Troubleshooting

Error: websocket-client library not installed → Run: pip3 install websocket-client --user

Connection Drops → The program automatically reconnects. No manual intervention needed.

False Positives (Existing coins show as new) → Run alpha.py reset to flush and rebuild the known symbols data.

No Alerts Triggering → Confirm Binance actually listed a new coin. Check your network connection.

How to integrate with a notification system? → Modify the alert_new_coin function in the script to add email/SMS/Webhook logic.

Notes

1. Network - Requires access to Binance WebSocket servers.
2. Memory - The symbol set consumes a few MBs of RAM.
3. False Positives - Occasional duplicate alerts may happen due to network instability.
4. Spot Only - Monitors spot trading pairs only, excluding futures/derivatives.
