Thanks, I already had that blanked I believe. So perhaps I have something else checked to cause this. Somewhere I read (a while back) that one cannot eliminate this, but I am too old to remember. Just for info I think I am up to date on Quicken Premier and windows 10.
Looking at the order of the what method of getting prices wins, it seems that they only one that would win over importing a CSV file is entering a transaction. So, importing a CSV should win, but there is way that might not seem like what is happening. Say the last day of the month is the 30th and you are going to be importing prices for that date, but today is the 3rd and is a trading day (or for mutual funds a day later) then if you do a One Step Update you will get a price from the financial institution, and since its date is later that it the price that is going to be shown unless you set the date of the portfolio back to the 30th.I might add that some financial institutions like Fidelity will actually give a date one day newer than you would expect.They update their prices early the next day and give it that date. In other words, if you update on the 4th they will send the closing price for the 3rd with a date of the 4th.
