Set MMP
What is MMP?
Market Maker Protection (MMP) is an automated mechanism designed to protect market makers (MM) against liquidity risks and over-exposure in the market. It prevents simultaneous trade executions on quotes provided by the MM within a short time span. The MM can automatically pull their quotes if the number of contracts traded for an underlying asset exceeds the configured threshold within a certain time frame. Once MMP is triggered, any pre-existing MMP orders will be automatically canceled, and new orders tagged as MMP will be rejected for a specific duration — known as the frozen period — so that MM can reassess the market and modify the quotes.
