the case seemed to be quite realistic to me as the sitution described is exactly what is happening with few broking and trading companies.brokers and traders at the operational level are responsible for doing fraudulent business for which the customer and the top management has to pay.
in this case the penalty imposed is one of the correct measure to reduce this malpractice for the time being.but for the long run the strategic team should decide to bring in latest technology which will not only give pop-up aerts at the back office but will also help in tracking the devils in disguise.
