Yes, you can trade any of the available currencies in your Multi Asset Margin account up to the withdrawable amount for each currency. The withdrawable amount is shown in the Wallet section under the Balances tab. You cannot sell more than this limit for any given currency.
What is the spot trading limit for margin currencies?
You can trade any available currency in your account, but only up to the withdrawable amount displayed in your Wallet section under the Balances tab. For example, if you hold 2,000 USDC and 1 ETH but your withdrawable amount is only 1,000 USDC and 0.5 ETH, you will not be able to sell more than the withdrawable amount of either currency.
This restriction ensures that sufficient margin remains allocated to support your open positions.
