When I downloaded transactions from Fidelity, it showed up as an Add Shares, which is wrong. I deleted it and instead added a Stock Split 10 - 1.Then I noticed that downloaded prices were in the /10 range going back to the end of July. I fixed July 31, and deleted the rest up to aug 9. ( I don’t care about daily price changes.). I hope it doesn’t download the wrong prices and overwrite again.. but for. that seems to be a pretty simple fix.
The best way to fix this is to manually edit the security prices for the dates in error. However, make sure you have your options set for manual entry override (which is the default).Deleting prices will cause the wrong pre-split prices to be downloaded on the next update to that security.Apparently, when Quicken updates a security, prices missing since the prior update are downloaded. The price downloaded for a given day is the historical value of one share today rather than one share then. In a 1:10 split, one share today was 0.1 share before the split, thus the price update is 1/10th the pre-split share price.A way to avoid the problem is to force a security update the day before the split, thus updating prices up to the split.Regardless of the work-arounds, ultimately the Quicken team should really fix the problem.
