This has been going on for a long time and through at least two versions. Periodically I detect that either my brokerage has not included a transaction in the one-step-update or Quicken has not recorded it. I can't tell which because I can't see what Quicken is processing.
I notice this by doing frequently doing comparisons of brokerage holdings to Quicken holdings in ONLINE. Today it was pretty obvious even before that because I was notified that Quicken recognized the presence of a new security in the update (prompted me to accept a new security or match with an existing one), but there was no transaction that referenced this new security (it should have been a buy). I then go back to the website for my brokerage and track down the missing transaction. It was one of 4 buys for the same day (3/9 if that makes any difference). I can't think of a reason that just one buy of 4 should be dropped.
Is there any way I can view the file that Quicken is processing to see if the problem lies with my brokerage or Quicken?
