The single transaction check is executed for a money market trade at two points when using Credit Risk Analyzer: when the trade is saved and when the check icon is clicked. The single transaction check is a function that checks whether a trade exceeds a predefined limit or not. The check is performed when the trade is saved to prevent unauthorized trades from being entered into the system. The check can also be performed manually by clicking the check icon before saving the trade to see the potential limit utilization.
