Performance Metrics

Caching

• Price cache hit rate: 80-90% (5s TTL)
• OHLCV cache hit rate: 60-70% (60s TTL)
• Overall cache efficiency: 70-80%

Rate Limiting

• Binance: 10 requests/second (configurable)
• Coinbase: 5 requests/second
• Kraken: 15 requests/second
• Per-exchange rate limiting with token bucket

Response Times
