## Multi-Exchange Architecture

The system now supports:

1. **Deribit** - Primary (derivatives focus)
2. **Bybit** - Secondary/Primary option (perpetuals)  
3. **MEXC** - Backup option (spot/futures)
4. **Binance** - Additional option (comprehensive markets)

Each exchange operates independently with unified interface, allowing:
- Simultaneous trading across platforms
- Risk distribution
- Market opportunity maximization
- System redundancy and reliability

## Conclusion

Bybit integration is fully implemented and ready for testing. The implementation provides enterprise-grade multi-exchange support while maintaining code simplicity and operational safety. Once credentials are configured and testing is complete, the system will have robust multi-exchange trading capabilities with Bybit as a primary option alongside Deribit.
