BBook-execution set up

Please note! A more detailed and visual description of the setup steps is available in the guide on Aggregator Settings and Instruments Availability.

1. Creating Aggregator settings for the BBook account

Account source type should be set to Indicative, since this type of account only requires indicative prices that will be executed within the platform.

Account ID - select the provider account (Real) from which the price stream will be sent to the BBook account and then to client accounts configured for BBook execution.

Important! All Account IDs of Real accounts that receive prices for the required instruments must be added to the setting.

The BBook executor setting must also be enabled for all added Real accounts. This allows orders to be executed and makes additional settings available. Click Edit to make the required changes and enable BBook executor. When the checkbox is enabled, the following settings become available:

• Group orders interval (ms) - if less time has elapsed between orders with the same trade side and amount for the same instrument than specified in this parameter, the orders will be grouped and executed together.
• Same price interval (ms) - guarantees that if less time has elapsed between orders with the same trade side and amount for the same instrument than specified in this parameter, such orders will be executed at the same price.
• Execute any volume - allows accounts using these Aggregator settings to close positions regardless of available liquidity in the order book.

When BBook executor is enabled, some settings can also be additionally edited in the Overriding instrument sets sidepage:

• separate Order type sets - sets of order types available for trading;
• separate Schedules - trading calendar schedules.

When finished editing, click Create or Save to save the created or edited setting.

2. Creating and setting up an account for BBook execution

To create this type of account, go to Access ➝ Accounts, click Create account, and configure the following settings:

Please note! You cannot trade on this account because it receives indicative prices only. To trade, create a separate account (or select an existing one) and apply the setting from the next step to it.

3. Aggregator settings for an account with BBook execution

Next, create aggregator settings for client accounts with BBook execution. Set Account source type to BBook, and in the Account ID field select the internal account for BBook execution created in the previous step.

If necessary, you can remove the preset Internal account filter and set one of the client accounts as the BBook executor. This configuration has a narrow use case and is required only by certain regulators. It is recommended to consult the Unity team before using it.

Please note! To trade on BBook, such aggregator settings must be applied to the client account.
