技術深入
- The tick size reduction utilizes a decimal-based pricing model adjustment within the HKEX Orion Trading Platform (OTP-C).
- Order matching algorithms were recalibrated to handle increased message traffic resulting from tighter bid-ask spreads.
- The system update involves a modification to the 'Price Increment Table' stored in the exchange's core matching engine.
- Latency benchmarks for the matching engine were audited to ensure that the increased order frequency does not degrade throughput performance.
