Real-time cryptocurrency funding rate scanner that identifies profitable opportunities with negative funding rates on Binance futures markets.

Features

• Smart Scanning: Monitors 40+ major cryptocurrencies for negative funding rates
• Risk Management: Built-in safety filters (volume, leverage limits, stop-loss)
• Scoring System: Combines funding rate, price trend, and trading volume
• Signal Classification: STRONG / MODERATE / WATCH alerts
• No API Key Required: Uses public Binance API endpoints
• Historical Tracking: Saves scan results to JSONL for analysis

How It Works

When funding rates are negative, longs receive payments from shorts. This creates a profitable opportunity to:

• Open a long position
• Collect funding fees every 8 hours
• Benefit from potential price appreciation

The scanner filters opportunities by:

• Minimum absolute funding rate (0.05%)
• Minimum 24h volume ($10M)
• Price trend analysis
• Composite scoring algorithm

Usage

Basic Scan

node scan.js

With Custom Config

node scan.js --max-leverage 2 --min-volume 20000000 --stop-loss 0.15

Automated Monitoring (Cron)

# Add to OpenClaw cron - scan every 4 hours
openclaw cron add "0 /4   " "cd ~/.openclaw/workspace/skills/crypto-funding-alert && node scan.js"

Configuration

Edit the SAFE_CONFIG object in scan.js:

const SAFE_CONFIG = {
  maxLeverage: 3,          // Maximum leverage (1-5x recommended)
  maxPositionPct: 0.3,     // Max position size (30% of capital)
  stopLossPct: 0.10,       // Stop-loss percentage (10%)
  minVolume: 10000000,     // Minimum 24h volume ($10M)
  minAbsRate: 0.0005,      // Minimum funding rate (0.05%)
  maxCoins: 5,             // Max simultaneous positions
};
