Features

Changes to MMP

This release introduces multiple changes to the Market Maker Protection functionality:

  • The Max Quote Quantity parameter is now mandatory within the Market Making Protection (MMP) configuration.

  • The precision of MMP configuration limits is restricted to a maximum of four decimal places.

  • MQQ is strictly enforced on all MMP orders, thereby limiting their maximum size.

  • MQQ is the only parameter used for calculating MMP margin; the Quantity Limit is no longer used if it exceeds the MQQ value.

  • MMP orders on options are now prohibited for Standard Margin (SM) users. 

  • The "MMP enabled" flag is now applied per subaccount, transitioning from a per-main-account setting.

  • Unified combo MMP order quantity (used for MQQ contribution) of SM users to be like for PM users. In both cases combo order quantity is used instead of sum of leg amounts.

For more information about Max Quote Quantity please refer to the MMP Article on the Deribit Knowledge Base.

Warning

The previously planned features, New inverse future spreads pricing (where size calculation would use the minimum mark price of legs) and Quote rejection (where rejection of one side of a quote would automatically reject the other side), have been cancelled and will not be integrated into this release.

Voice Broker Updates

The following features and updates related to the Voice Broker were implemented in this release:

  • Broker Subaccount Access:

    • The Voice Broker API methods are now usable by broker subaccounts.

    • Subaccounts are permitted to use the broker API on behalf of their main account, with all actions treated as being made by the main account.

    • Functionality is restricted to clients the subaccounts onboarded themselves; subaccounts cannot access other subaccounts' or the main account's clients.

    • The main account retains the ability to manage and trade using its subaccounts' clients.

  • Block Trade Enhancements:

    • Brokers can now initiate a block trade without pre-providing client(s). The trade can be accepted (via signature) by users not present on the broker's client list.

  • API Scope Change:

    • Broker API methods related to client setup now require the block_trade scope.
