Not a margin account

[umeshy]

I'm getting error in below statement, please suggest reason for the error:

BinanceApiMarginRestClient marginClient = factory.newMarginRestClient();
		String marginlistenKey = marginClient.startUserDataStream();
		

Error: com.binance.api.client.exception.BinanceApiException: Not a margin account.

You probably don't have an open margin account in binance.
Tip:

Under “Balance Details”, click on “Margin” so you can start opening a Binance margin trading account.
You need to complete the KYC identity verification and ensure that your country is not part of the blacklist. 
Enabling 2FA is also mandatory. After that, you will see a reminder regarding margin trading's risks.
