- Implement FIX protocol (Financial Information Exchange) or custom binary protocols to meet traditional financial institutions' connectivity needs.
- Institutional-Level Function Support
- Develop institution-exclusive features like Block Trading, algorithmic orders (TWAP/VWAP), and multi-account risk management (Risk Engine).
- Design security control modules including Rate Limit, IP whitelisting, and Multi-Factor Authentication (MFA).
- Integrate with clearing systems to support T+0 settlement, automatic reconciliation, and other institutional compliance requirements.
- Performance and Stability Assurance
- Enhance API service performance through load balancing, connection pooling, and asynchronous processing techniques.
- Design Circuit Breaker, Fallback, and retry mechanisms to ensure high availability (99.99% SLA).
