Thanks for your reply!The TDAmeritrade web site only provides current prices which include after hours trades. No historical data is available from the TDAmeritrade web site. IMO this is pretty lame! However, since I am reconciling a monthly paper statement the prices stated in the printed document should be month-end closing prices. This appears to be the case since the statement prices agree with Yahoo and Seeking Alpha for the month-end close. It is only the prices that are downloaded into Quicken, presumably from Quicken's supplier, that are different. To my knowledge I am not downloading prices from TDAmeritrade, only via Quicken's One Step Update from Quicken's supplier. That is why I posted my issue with the Quicken community.If the Quicken One Step Update can be configured to download from multiple sources then I would ask how to verify which source is being used. This is a new one for me and I have used Quicken since the early 90's/I can guarantee that the stock ticker symbols are correct. I reconcile by matching these symbols since the names don't exactly match.
