This key has no trading permission for the selected markets
The API key is valid, but some of the markets you selected have no trading permission, so the account wasn’t saved. Turn on trading permission on the exchange and save again.
What it means
The API key passes verification, but some of the markets you selected in Trade have no trading permission. The account wasn’t saved. The message lists the markets that lack permission.
Why it happens
The API key is read-only, or trading is enabled for only some markets.
What to do
In the exchange’s API management page, enable the permissions listed under Enable in the API key section of the add-account window (named exactly as on the exchange). Some exchanges grant trading per product, for example Bitget needs UTA trade with Read and write, and a KuCoin unified account needs Unified. ZML Trade does not need or use withdrawal permission, so leave it disabled.
Go back to Trade and save again.
Leave out any market you don’t plan to trade when you add the account. For the requirements, see Connect an exchange.
