Unlinking

To unlink a broker:

linkedBrokerManager.unlinkBroker(
    linkedBroker,
    new TradeItCallback<TradeItResponse>() {
        @Override
        public void onSuccess(TradeItResponse response) {
            //successfully unlink the broker
        }

        @Override
        public void onError(TradeItErrorResult error) {
            // an error occured    
        }
    }
);
