As a finance professor, it's important to understand the concept of active trades in a customer's account. These are trades that have not yet been closed or settled, and are still considered ongoing. This means that the customer still has a stake in the trade and its outcome. Active trades are a crucial aspect of investment management and require careful monitoring and analysis. It's essential for both the customer and the financial advisor to keep track of these trades and make informed decisions to maximize profits and minimize risks. In essence, active trades are an integral part of the dynamic and ever-changing world of finance.
