BEFORE WE START!
OKX Demo trading account is not supported for on 3Commas. You can only trade with real funds when using OKX through 3Commas.
If you want to connect the OKX Futures account to 3Commas, you must first activate it on the OKX website! Please head to the end of this article to learn how to enable Futures on OKX.
If you don't yet have OKX account, you can take advantage of our new OKX Fast Registration feature. Just head to this page, create an OKX account and you will be redirected straight to the Fast Connection page.
IMPORTANT NOTICE
OKX are migrating their existing users that are located in an EEA country to their new my.OKX.com region specific service.
OKX has completed migration for EEA users to my.OKX.com, and connection via manual API key is now supported. Fast Connect will also be available soon. No action needed—detection is automatic!

III. Manual API keys creation
Reminders
Manual API key setup is now supported for my.OKX.com (EEA) accounts. Follow the steps below to connect Spot and Futures accounts.
For Non-EEA users: Only use manual API keys if Fast Connect doesn’t work. Manual API setup is more complex and may not work for all users.
1. Follow to API management page
Hover over the profile icon on the top right corner, and click on API button:
You must enable 2FA to add API keys. If you see this message, please follow OKX's instructions:
2. Click "Create APIs"
3. Give it a name
When you have multiple APIs, a proper name helps to manage it.
4. Choose the account where you want to create an API key
It includes all your main and sub-accounts.
5. Choose Linking third-party apps and choose "3Commas"
Can’t find 3Commas in the dropdown?
If "3Commas" doesn’t appear in the third-party app list, try using the Fast Connect method instead — it automatically links your account without needing to search manually.
Still can’t see it? Contact our support team for assistance!
6. Choose the "Trade" permission
7. Enter the Passphrase
It's a "password" for the API key. Remember or save it somewhere safe, as you can't add API to 3Commas without it.

10. To see API keys, click on Show info
11. Save your created API keys

FAQ
Why can’t I close my position on OKX? ("You're leading trades in Long/Short mode" error)
If you're using an OKX Copy Trading Lead account, position closing behavior is restricted by OKX. Positions can only be closed at market price, and amounts can’t be customized. Bots are not designed to work with Copy Trading accounts, so issues may occur.
More info: Lead Traders FAQ – OKX
Why do I get a “Balance limit reached” error when opening a trade?
This error typically means your position exceeds OKX contract or leverage limits. You’ll need to adjust your trade size or leverage according to OKX’s contract rules.
Check OKX contract rules here: OKX Swap Info
Why is my OKX balance showing incorrectly on 3Commas?
Make sure your funds are in the Trading Account, not in Funding, Margin, or Earn accounts. 3Commas can only access funds located in the Trading section of your OKX wallet.
Tip: Transfer your assets to the Trading Account using OKX’s internal transfer option.
How do I transfer funds to the Trading Account on OKX?
Go to the Assets drop-down on OKX and click Transfer. Move your funds from Funding to Trading Account. Only assets in the Trading Account can be used by bots for Spot trades.
