Managing trading accounts
Important: This product may not be available in your location or jurisdiction.
Overview
Sub-accounts allow Bullish Institutional customers to set up multiple Trading accounts under their Institution account, each with separate balances, positions, and users. Profits and losses are also tracked individually within each Trading account, which enables Institutions to isolate and manage different trading strategies or keep customer accounts separate. Institutions may have up to a maximum of 50 Trading accounts.
To simplify management of funds, all deposits and withdrawals in Bullish are managed through a single Trading account called the Primary Account. Funds may be transferred between the Primary Account and any other Trading accounts within the same Institution account, free of charge via the Bullish Trading API or the Bullish trading web interface.
Currently multiple Trading accounts are only available for Institutional customers.
Users and Permissions
Once a user has been on-boarded onto Bullish they can be granted access to one or more Trading accounts under their Institution. User permissions are set individually for each trading account. For example, a user could have spot trading privileges on one Trading account but read-only access on another.
The section below indicates the allowed permissions based on the onboarding entity:

An Authorized Representative can create API keys in the Bullish UI to grant their users access via API. If a user requires access to the Bullish UI, the Authorized Representative will need to contact their Bullish Relationship Manager to update their permissions.
API Keys and Rate Limits
API keys are associated with a specific user and can be used across multiple Trading accounts which are chosen when the key is created. Since an API key can now be used to access multiple Trading accounts in a single session, the Trading API has been updated to require the target trading account (tradingAccountID) to be specified for each call. You can find the Bullish API guide at 
Overview | Bullish Developer Docs
API rate limiting is enforced per Trading account, regardless of the number of users accessing the account.
