Thanks to
this post from RickO, I recently became aware that many brokerages do not transmit brokerage transactions correctly to Quicken through their direct connect system. This results in incorrect balances and having to do frequent manual corrections to fix cash balances, sweep account balances, etc.
My question is: Which brokerages work well with Quicken?
By work well, I mean which brokerages' direct connect system correctly passes the transactions to Quicken so that balances are always accurate and don't require manual user intervention to keep them accurate?
I'm specifically interested in users' experiences with Vanguard, Fidelity, and Schwab, but would also be interested in experiences with other brokerages' direct connect systems as well. Thanks!
