This error appears when you're using Binance sub-accounts. Binance's API Trading Symbol Whitelist restricts a sub-account's Spot/Margin API trading to a set of pairs selected by the Master Account. If your bot tries to trade a pair that isn't on the whitelist, you'll see this error.

1. Log in to your Binance account and click [Profile] → [Sub Accounts].

2. Go to [API Management] under [Sub Accounts] on the left. Find the sub-account you want to enable the symbol whitelist for and click [Modify] next to it.

3. You'll be redirected to the API Management page. Click [Modify], then check the box next to [Enable Symbol Whitelist].

4. Click [Edit] next to [Enable Symbol Whitelist] to configure the whitelist pairs. You can search for symbol pairs here. Click [Add] to add a pair to the whitelist. You can add up to 30 pairs per sub-account API.

5. You can also view the most popular pairs. Click [Add] to add a pair to the whitelist.

6. Click [Import from favorites] to see your favorite trading pairs and add them to the whitelist.

7. To remove a pair from the whitelist, click [Remove] or [x] next to it. When you're done selecting pairs, click [Confirm].

8. Click [Edit] again to review the whitelisted pairs. Once confirmed, click [Save] on the [API Management] page.

9. Verify the request with 2FA.

You'll see that the [Enable Symbol Whitelist] box is now checked. This sub-account can now only trade the selected pairs in Spot/Margin markets via API.

The API Trading Symbol Whitelist lets you restrict sub-accounts' Spot/Margin trading to Master Account-selected pairs only. It's available to Master Accounts that have APIs set up for normal sub-accounts.

Here's what it offers:

Keep in mind: the whitelist only affects API trading. Sub-accounts can still trade any pair directly on the Binance website. The feature is currently available for Spot/Margin trading on normal and managed sub-accounts only.
