There were issues with the recent Fidelity changes which continue. The settlement account at Fidelity is designated on their website as "CASH HELD IN MONEY MARKET". Initially after the conversion this was not recognized in Quicken. This was changed and the Cash held Money Market was recognized as a security in Quicken but it was also shown as CASH in Quicken so the account balance was incorrect because it was double counted. I was advised by Quicken to add an adjustment to subtract the cash balance. I was skeptical but did this. The balance was correct at the time of the adjustment but as I did more transactions the cash balance in the Quicken program shows a negative number although the Money Market fund which shows in Quicken as a security does adjust.
As I understand it the settlement account at brokerages is the money that is available for investment and is the balance that quicken shows in the transaction tab. It seems to me that calling the "settlement account" at the brokerages "cash" is a problem since they are not held in cash at most brokerages but are held in money markets which are a security. Maybe Quicken needs to recognize the settlement account as Fidelity does as Cash held in Money Market and not show the Money Market in the settlement account as a security and then show the money market amount in the settlement again in the cash balance.
I checked my Vanguard account because they also have a settlement account which is held in money market. Quicken is also showing a cash balance in Vanguard account. I have no idea where that comes from since there is no cash and the settlement fund held in money market is shown as a security correctly. This creates an incorrect account balance and requires continual adjustments if you want correct account balances in Quicken.
Please let me know if there is something I can do in the program to address my continual incorrect balances in my Fidelity and Vanguard brokerage accounts
