## Troubleshooting

**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.

## Configuration File

Alert configurations are stored at: `~/.config/crypto/alerts.json`
