You don't need a separate subaccount to trade futures. You can trade directly from your main account using cross-margin.
What is cross-margin?
Cross-margin uses all eligible collateral in your main account (EUR, GBP, and USD) to support your open futures positions. Rather than assigning margin to individual positions, your entire eligible balance acts as shared margin across all of them — which can help reduce liquidation risk by pooling collateral.
Can I separate risk between positions?
Yes. While futures trading on your main account uses cross-margin, you can still create a separate subaccount if you want to isolate funds from your main balance. Funds in a subaccount are margined independently and don't interact with your main account, letting you limit how much collateral is exposed to futures trading. See What are subaccounts used for on One Trading? for details.
Leverage
Leverage limits are unchanged — eligible clients can access up to 10x leverage.

Investing involves risks. The value of investments can go up as well as down and you may receive back less than your original investment or lose your entire investment. Investing with leverage means the value of your investment fluctuates more than the price of the underlying asset. One Trading does not provide investment advice and investors should make their own decisions or seek independent advice.
