Algorithmic trading rules: exchanges must enforce system capacity, risk controls, order-to-trade penalties, audits and reporting. Algorithmic trading-orders generated by automated execution logic-is subject to operational, risk-management and surveillance requirements. Exchanges must ensure system capacity and upgrades, classify and route algorithmic orders through member servers, prohibit strategies and access that harm price discovery or disadvantage members, and impose multi-layered order-level risk controls including limits on order types, price, size and position. Members need prior exchange approval, real-time monitoring, audit trails, empanelled system audits and unique order identifiers; exchanges must limit order rates, apply economic disincentives for excessive order-to-trade activity, detect dysfunctional algorithms and report metrics and incidents to the regulator.
