Error: ccxt library not installed → Run: pip3 install ccxt --user

Error: Unsupported exchange → Check exchange spelling. Refer to the supported exchanges list.

Error: Trading pair does not exist → Check trading pair format, e.g., BTC/USDT, ETH/USDT.

Alert not triggering → Confirm alert conditions are correct. Run alert-check to check manually.

API Limits → Some exchanges have strict rate limits. Use --interval to adjust the refresh frequency.
