I have two accounts on my Scottrade account; they used to work fine but as of a couple of days ago they are both showing the balance from one of the accounts.
I've have these two brokerage accounts working correctly for years; one has a balance of ~$4 and the IRA account has a 5-digit balance. As of a couple of days ago they are now showing the same balance, and some very odd behavior (showing over $1 million cost basis which is completely incorrect).
