Sub-Account Management for Perpetual Futures

What Are Sub-Accounts?

Sub-accounts are independent trading accounts that exist under a single master (parent) account. Each sub-account has its own separate balance, open positions, margin calculations, order history, and trading settings. From a risk perspective, sub-accounts are isolated from each other; a liquidation in one sub-account does not affect the balances or positions in another.

The master account acts as the administrative hub, with the ability to create new sub-accounts, transfer funds between them, view consolidated performance across all sub-accounts, and manage access permissions for team members. This hierarchical structure mirrors the account architecture used by institutional trading desks at major centralized exchanges.

On a perps.studio-powered exchange, sub-accounts are a native feature that works seamlessly with all other platform capabilities, including cross-margin, isolated margin, advanced order types, and the referral system. Each sub-account can be configured independently, allowing different strategies to operate with different risk parameters.

Use Cases for Sub-Accounts

Sub-accounts serve a wide range of use cases across different trader profiles:

• Strategy Isolation: A trader running multiple strategies (e.g., a momentum strategy and a mean-reversion strategy) can use separate sub-accounts for each. This keeps the PnL and risk of each strategy completely independent, making performance attribution straightforward.
• Risk Budgeting: Institutions can allocate specific capital amounts to different sub-accounts, effectively creating risk budgets. Each sub-account can only risk the capital allocated to it, preventing any single strategy from consuming the entire portfolio's risk capacity.
• Team Management: Trading firms with multiple traders can assign each trader their own sub-account. This enables individual performance tracking, risk limits per trader, and clear accountability.
• Client Segregation: Asset managers who trade on behalf of multiple clients can use sub-accounts to maintain strict separation between client portfolios, ensuring that each client's assets and trading activity are isolated.
• Testing and Development: Traders developing new strategies can use a sub-account as a sandbox, testing with real market data without risking their main trading capital.

Sub-Account Creation and Fund Transfers

Creating and managing sub-accounts on the perps.studio terminal is designed to be fast and intuitive:

Creating Sub-Accounts: From the master account dashboard, users can create new sub-accounts with a single click. Each sub-account is assigned a unique identifier and can be given a custom label (e.g., "Momentum Strategy," "BTC Scalping," or "Client A Portfolio") for easy identification.

Fund Transfers: The master account can transfer funds to and from any sub-account instantly. These internal transfers do not involve any on-chain transactions or fees; they are simple balance adjustments within the platform's account system. This allows for rapid capital reallocation between strategies as market conditions change.

Balance Overview: The master account dashboard displays the balances of all sub-accounts in a consolidated view, showing total equity, allocated capital, available reserves, and unrealized PnL across the entire account structure. Individual sub-account details are accessible with a single click.

The number of sub-accounts that can be created is typically generous, with limits set by the underlying protocol. Most traders will find the available sub-account capacity more than sufficient for their needs.

Risk Isolation Between Sub-Accounts

One of the most important properties of sub-accounts is risk isolation. Each sub-account operates as an independent risk unit with its own margin calculations, liquidation thresholds, and position management. The key implications of this isolation are:

• Liquidation Containment: If a sub-account's positions are liquidated, only the balance in that specific sub-account is affected. The master account and all other sub-accounts retain their balances and positions unharmed.
• Independent Margin Modes: Each sub-account can use a different margin mode. One sub-account might use cross-margin for a diversified portfolio, while another uses isolated margin for high-leverage speculative trades.
• Separate Leverage Settings: Leverage can be configured independently per sub-account, allowing conservative and aggressive strategies to coexist under the same master account.
• Independent Order Management: Open orders, positions, and trade history are scoped to each sub-account. There is no cross-contamination of trading data between sub-accounts.

This isolation is not just a convenience feature; it is a fundamental risk management mechanism that professional traders rely on to protect their capital from strategy-specific risks.

Consolidated Reporting and Analytics

While sub-accounts operate independently for risk purposes, the master account provides consolidated reporting that gives a holistic view of performance across all sub-accounts:

• Aggregate PnL: Total realized and unrealized PnL across all sub-accounts, with the ability to drill down into individual sub-account performance.
• Capital Allocation Summary: A visual breakdown of how capital is distributed across sub-accounts, including utilization rates and available reserves.
• Performance Attribution: Compare the performance of different sub-accounts side by side to evaluate which strategies are contributing most to overall returns.
• Trade History Export: Consolidated trade history across all sub-accounts can be exported for tax reporting, compliance documentation, or integration with external portfolio management tools.

This combination of isolated execution and consolidated reporting gives institutional users the best of both worlds: strict risk separation for trading, and comprehensive oversight for management and compliance.

API Access for Sub-Accounts

Each sub-account can be accessed independently through the perps.studio API, enabling programmatic management of multiple strategies. API keys can be generated per sub-account, with customizable permissions (read-only, trade-only, full access) that control what operations are allowed through each key.

This API architecture supports common institutional workflows:

• Automated Strategy Deployment: Trading bots can be assigned to specific sub-accounts, executing their strategies independently without interfering with each other.
• Portfolio Rebalancing Scripts: Automated scripts can monitor balances across sub-accounts and transfer funds as needed to maintain target allocations.
• Risk Monitoring Systems: External risk management tools can connect to the API to monitor exposure across all sub-accounts and trigger alerts when predefined thresholds are breached.
• Reporting Integration: Trade data from all sub-accounts can be pulled via API and aggregated in external reporting and analytics platforms.

The per-sub-account API key system also provides security benefits. If a single API key is compromised, only the associated sub-account is at risk, not the entire master account.

Sub-Accounts for Exchange Operators

For whitelabel operators, offering sub-account functionality is a powerful signal that the exchange is built for professional use. This feature is frequently cited as a requirement by institutional traders evaluating new platforms, and its presence can be the deciding factor in attracting high-value users who generate significant trading volume.

The perps.studio admin panel provides operators with visibility into sub-account usage across their platform, including the number of users utilizing sub-accounts, the total number of sub-accounts created, and aggregate trading activity across sub-accounts. This data helps operators understand how their institutional user base is using the platform and identify opportunities to better serve this segment.

Sub-account functionality requires no additional configuration or setup from the operator. It is included as a standard feature of the perps.studio whitelabel terminal and is automatically available to all users on the exchange.
