Why it matters
In algorithmic trading, running multiple strategies at once is the norm. Scalping, arbitrage, market making, mid-term positions - they all operate in parallel. The challenge is obvious: when everything sits under one account, losses from a single strategy can easily wipe out gains from others.
For me and my team, this was exactly the problem we faced. Our overall PnL curve kept swinging too wildly. Even if three strategies were profitable, one bad move could erase everything. We needed a way to separate risks and measure performance without one strategy dragging the others down.
That’s when we started looking into sub-accounts.
How sub-accounts work
Think of a sub-account as a separate “pocket” inside your main account. It has its own balance, permissions, and API keys. Each strategy can live in its own space, completely isolated from the others.
We decided to test sub-accounts on different exchanges to see how well they would fit into our workflow.

-Support multiple levels of access and separate limits
-API integration makes it easy to track strategies individually
-General accounts can open up to 10 sub-accounts, while institutional clients can scale much higher

-Simple way to split assets and strategies under one main account
-Each sub-account can be managed independently through API keys
-Especially useful within their Market Making Program, where dozens of strategies may run side by side
-For institutional clients, thousands of sub-accounts can be created, allowing large teams to manage strategies at scale

-Designed mainly for institutional and VIP users
-Dozens of sub-accounts can be created with flexible access rights
-For VIP and institutional clients, the limit can reach up to 200 sub-accounts
What came out of it
🔹 After three months of testing, the numbers spoke for themselves.
🔹 Our scalping sub-account closed the quarter at –12%.
🔹 Arbitrage finished with +15%.
🔹 Market making delivered a steady +8%.
If we had run all of these under one account, the scalping losses would have eaten away much of the gains, and our net performance would have been close to break-even. But with sub-accounts, profits and losses stayed separated. The final result across all strategies was a clear +11% overall gain - and most importantly, the equity curve was far more stable.
Final thoughts
For us, sub-accounts turned out to be more than just a convenience feature. They became a genuine risk management tool. By isolating strategies, we could track performance more transparently, control exposure, and test new ideas without jeopardizing the core portfolio.
In today’s volatile crypto market, that separation can make the difference between an unstable curve and long-term sustainable growth.
