    LMAX Digital closing prices launch

  • Venue controls

    • Volatility bands more

      Volatility bands are set per order book and are different for both price makers and takers. The bands reject a participant’s order if, for price makers, the price on order is more than a defined percentage away from their last accepted price. For price takers, the order is compared against the top of book price. Where a volatility band is breached, new orders from that participant will be rejected and an internal approval process is triggered to assess whether the volatility bands must be widened to enable the participant to continue to trade. Please view the Volatility Bands

    • Order throttling more

      LMAX Digital operates real-time monitoring and alerting of the message rates and performance of all orders placed on production systems, on an individual session and aggregate basis. Order per second limits are set per FIX session, which applies for all instructions received over the FIX session. If the limit is breached, the FIX session is disconnected and re-connection blocked for 15 seconds. The default setting is 750 updates per second but can vary for maker participants according to number of instruments and depth priced.

    • Pre-trade controls more

      Clip Size Limits set a maximum order size for each participant. Orders in excess of the clip size limit are rejected.

    • Working order limits more

      Working Order Limits restrict the total unfilled passive order volume that can be submitted ‘per participant’ on each instrument. Orders with volume that will breach the limit are rejected.

    • Post trade controls more

      Net Open Position Limits are set per member. Email alerts are sent at 75%, 85% and 95% utilisation of a participant's limit. At 95% utilisation all trading is disabled for the member. Typically clip size limits are set to 5% of the credit limit to avoid a breach of 100%.

    • Kill switch more

      Where a participant’s NOP utilisation exceeds 95% they are automatically disconnected and all working orders cancelled. Where a participant breaches their set order update limit, they are disconnected and all orders cancelled. A participant’s activity can be disabled at any point in time by removing their credit limit.

These consist of a mixture of targeted microbenchmarks that evaluate the performance of specific aspects of the system, and end-to-end tests that either generate synthetic load or replay production traffic against dedicated test environments.
