Real-time notifications for Market Maker Protection (MMP) triggers. This subscription provides feedback when MMP protection is activated for a given index, enabling clients to react promptly when protection is triggered.
Upon MMP being triggered for a given index, the client will receive a trigger notification containing:
- frozen_until: Unix timestamp in milliseconds indicating until when the MMP is active (orders remain blocked). If
frozen_until: 0, it means MMP will remain active until manually reset using theprivate/reset_mmpmethod. - index_name: Index identifier of derivative instrument on the platform. For Block RFQ MMP, this will be “all” when triggered by trade count limit.
- mmp_group: Triggered MMP group (optional, appears only for Mass Quote orders trigger)
- block_rfq: If true, indicates that the MMP trigger is for Block RFQ. Block RFQ MMP triggers are completely separate from normal order/quote MMP triggers.
This notification allows the client to track MMP state per index and avoid submitting new orders that would be rejected due to ongoing MMP freeze.
