Trading Sub-Account
Streamlined account management and multiple strategies in a single solution
Streamlined account management and multiple strategies in a single solution
As part of the continuous improvement of its trading risk systems, B3 will implement a new optional functionality for validating account limits in the LiNe system. To enable this functionality, a new field called "Trading SubAccount" will be introduced, providing greater flexibility in account management during trading sessions.
With this new feature, investors can specify a valid account registered with B3 in the "Trading SubAccount" field, intended exclusively for assessing limits in the LiNe system. It must be different from the account informed for Settlement/Custody.
The update will be reflected in the new specifications for the FIX and Binary protocols, scheduled to be available soon. We recommend that all participants review the new specifications to ensure the smooth integration and correct operation of this new functionality.

Product benefits

Creating the Trading Sub-Account assessment in the LiNe system reduces costs, simplifies accounts and maintains risk control unchanged in the execution of different strategies.
The Trading Sub-Account will allow multiple risk strategies to be managed at the investor account level (CPF/CNPJ), while preserving the centralized control rationale already performed by the LiNe system. This provides a more efficient experience, without changing major risk management processes.
Participants must continue to inform the account used for Settlement/Custody in the current field (tag 1-Account). Optionally, they can inform an additional account of the same investor in the "Trading SubAccount" field, which will be used by the LiNe system only for the analysis of trading limits.
It should be noted that the "Trading SubAccount" field must be completed with an account value that is different from the one informed in the 1-Account tag, but which belongs to the same investor, thus complying the rules established in the LiNe conceptual manual.
The LiNe system is a tool integrated into the PUMA trading platform, designed for market participants to set pre-trading limits and monitor their clients' activities. It allows participants to define pre-trading limits and monitor transactions in real time.
