I'd first check a Portfolio View for that account and see if, perhaps, some security or currency prices were incorrectly downloaded. If that is not the issue, then it seems like there must be something wrong in the register.
Yes, that's what I've done. I checked the portfolio view, and all is
well. I looked at the transactions to see if something looked on on the
transaction register, but that looks fine too: just the way I left it.
Since I enter all my stock prices manually, there should be any weird
download issues, but the stock transaction registers look just fine too.
Perhaps you could post screenshot(s) displaying the 'out-of-whack' instances of the Roth account's balance. (keep in mind that these are public forums if you need to redact anything)
Maybe in doing so, it'll provide a little more insight into the anomaly.
If memory serves me, the last time that I experienced a strikingly large imbalance was when my investment account's Money Market Fund had an inaccurate net asset value. Something in the range of $1,000.00 instead of it's par $1.00.
There really isn't much to show; the number on the this view (The net
worth on the Summary sheet) seems to be correct.
But the number on this view (the Net Worth Report page) has another digit:
Since the Net Worth report lists all the accounts included, its pretty
darn easy to see the the amount of the one account is inflated by that
same extra digit of $$. Nice, but not true!!
Without knowing how the report is created, it's really hard to do
anything except compare the totals. From the graphical view, it's
possible to see that "something" took a stratospheric leap in March,
2018, but there is nothing in the portfolio view or the transaction view
to support that. I have only one or two transactions a month in this
account, so there's really nothing to see!!
Okay...the current prices are all in order. The current prices in the
top box match up with the purchase record. March was when I reconciled
this account to with pre-MoneyDance Quicken records, so I'm assuming
that created the problem. Now the account balances in MoneyDance are
correct, but somewhere the software is picking up something I can't see?
