Self-Match Prevention is only supported in which trading mode?

• A. Pre-market
• B. After-hours
• C. Continuous trading
• D. Auction period

Answer: (C)

Self-match prevention stops a trader’s own orders from being matched against each other, preserving market integrity during price formation. In continuous trading, orders are arriving and being matched in real time, so the system can enforce this rule as every new trade is evaluated against the live order book. That real-time, one-by-one matching environment is exactly where self‑match prevention is implemented to prevent accidental or intentional self-dealing. In pre-market or after-hours sessions, or during an auction period, the matching logic is different—often batch-based or session-specific—so the specific self-match protection isn’t applied there. Hence self-match prevention is available in continuous trading only.
