What is a Limit Plus order?

• A. Place limit order into both CLOB and MPOB simultaneously (with minimum execution quantity).
• B. Place limit order into MPOB only
• C. Remove limit entirely when price moves against the trader
• D. Place limit order into CLOB only

Answer: (A)

Limit Plus is a routing style that exposes your order to more liquidity by posting it in both venues at once while keeping your limit price intact. By sending the limit order to both the Central Limit Order Book (CLOB) and the Multilateral Public Order Book (MPOB) simultaneously, you increase the chances of an execution because you’re tapping into two pools of liquidity rather than one. The inclusion of a minimum execution quantity means any actual fill must meet or exceed that size, so you avoid getting tiny, value-less partial fills and ensure that trades are meaningful. This combination—posting to both books and requiring a minimum fill size—best describes a Limit Plus order.
