To improve the user experience throughout the CEX.IO ecosystem, we intend to simplify trading on CEX.IO Spot Trading via the mobile app and web trading terminal. To make this happen, we’ll introduce a new Wallet account on Spot Trading (prior Exchange Plus), which offers:

  • The ability to store user funds on the CEX.IO Wallet balance.

  • Trading on the Main Spot Trading account from the CEX.IO Wallet balance.

These changes will eliminate the need for manual internal transfers between CEX.IO Wallet and Spot Trading before, and after, executing orders.

However, these updates will also require additional balance checks and other actions before, and after, every order. This could potentially have a negative effect on order execution time, which is vital for API trading.

So to ensure the best quality experience for all traders, we've decided to separate UI and API trading. As a result, API trading on Spot Trading will be available only via sub-accounts, in order to maintain reliable, high-speed order execution. These changes are scheduled to take effect on November 13, 2023.

How will this affect API traders?

API traders should keep the following in mind:

  • Once these changes take effect, the New Order API method will no longer be available for the Main account (accoutld=“”). Please place new orders via API on sub-accounts.

  • All open Main account orders will remain active after the updates. If necessary, they can be canceled using the Cancel Order API method.

Please note that these changes apply only to API traders who use Spot Trading. We’ll communicate further when direct trading from the CEX.IO Wallet will be launched.

How to prepare for this update

We strongly recommend that all API traders move funds used for API trading from their Main accounts on Spot Trading, to dedicated sub-accounts before November 13, 2023. To do so, review the following tips:

  1. If you don’t have a sub-account on CEX.IO Spot Trading, you can create it via the Create Account API method, or the Finances page. For the latter, navigate to the account selector, and click the Create Sub-account button.

  2. To move funds from the Main account to sub-accounts, use the Internal Transfer API method, or perform these steps as listed on the Finances page.

  • Select a sub-account in the account selector, and click the Add funds button.

  • Define an asset you want to transfer, and choose the Sub-account Transfers method.

  • Pick the Main account as the source from which to withdraw funds, and select a specific sub-account as the destination point.

  • Indicate the amount of funds, and click the Add funds button.

  • Confirm the transaction using the Deposit button.

3. Please switch your trading bots to executing trades only via specific sub-accounts. To do so, consider using specific sub-account names in the “accountId” fields, instead of the Main account name (accountId=“”) before the update release.

In addition, if you plan to deposit funds for API trading before the update release, consider funding a dedicated sub-account right away, to avoid additional actions once the changes take effect.

In order to deposit funds from the CEX.IO Wallet to a trading sub-account, use the Funds Deposit from Wallet API method, indicating a specific sub-account “accountId.” Alternatively, make an internal transfer from the Finances page, with the following steps:

  • Select a sub-account in the account selector, and click the Add funds button.

  • Define an asset you want to transfer, and choose the CEX.IO Wallet method.

  • Select a specific sub-account as the destination point.

  • Indicate the amount of funds, and click the Add funds button.

Confirm the transaction using the Deposit button.
