Which function would you use to monitor real-time fund flows across different asset classes?

The function used to monitor real-time fund flows across different asset classes is 'FLOWS'. This function is designed specifically to provide insights into the movement of capital among various asset categories, allowing users to track shifts in investments and understand market trends in real-time. By utilizing 'FLOWS', users can observe how much money is entering or leaving specific asset classes, making it invaluable for analyzing the current investment landscape and assessing market sentiment.

While the other options may provide useful information on different aspects of market data, they do not focus specifically on the tracking of real-time fund flows across various asset classes, which is the primary function of 'FLOWS'.
