Changes in the net value of general funds directly reflect returns and do not require any personal information. Monetary funds announce returns every day, not net values, and pay dividends once a month. Who else but you can know how much dividends you have each month? It is not a simple share x net value.

Instead, we need to add up the daily income, and there are subscriptions and redemptions in between.

Now it's nice to let you manually enter the monthly dividend amount yourself.
