Crypto perp exchanges charge a funding rate every 8 hours. When rates diverge across exchanges you can go long on the low-rate side and short on the high-rate side delta neutral, collecting the spread. HOW IT WORKS • Fetches live funding rates from all 3 exchanges • Calculates: (rate_high - rate_low) × 1095 - 3% fee drag • Classifies: LOW (5-10%), MEDIUM (10-20%), HIGH (20%+) • Alerts fire the moment a spread crosses your threshold
