You should add unique Security ID’s to any securities that has not got one, it’s never to late.
Are you using the latest build of the Q & ER that is v1018? If not update and try again.
If you are and all your securities were returning quotes, but have now stopped, there is not much you can do with that setup.
Perhaps time to try a new way of obtaining quotes and importing them into Moneydance.
I have given up on the Q & ER extension.
I am using a free stand-alone program that was originally developed to help out users of MS Money when Microsoft stopped supporting that product. The program is in java, like Moneydance and thus runs on Windows, Mac and Linux computers.
I entered the list of symbols you posted and the stand-alone returned quotes for all of them, see screen shot.
Example FBIOX is traded on the Nasdaq and the on the sources web site close is quoted at 8:00PM EDT.
The stand-alone program was run on a computer in the UK. BST is 5 hours ahead of EDT thus in BST time the close of 8PM+5hours equals 1am. A close on Friday 8PM EDT would be reported as a close 1AM Saturday BST. Run the program in a different time zone get a different result.
