It is so because Yahoo gets them from different data vendors. It may happen that quotes on Yahoo Current page and Yahoo Historical pages differ. To verify always go to relevant page (see links above) and check the quote on Yahoo Finance site directly. It is important to understand that AmiQuote is just the downloader (like Internet Explorer) and it does nothing except downloading the data, so if you belive that there is a bad quote – it is not AmiQuote, but rather Yahoo problem. Of course you may use historical everyday as well if you have time and fast internet connection. So recommended usage is to use Yahoo Current mode everyday, and Yahoo Historical once a week.

Current mode is also much faster as it downloads as many as 200 symbols at once, while historical must download one by one. Why using two sources? That’s simple: current mode gives data during trading session, while historical is only updated many hours after markets close so both compliment each other.
For example MSFT historical page is here: (again AmiQuote uses rather plain text link “Download data” (URL is dynamic, so you must click on “Download data” link on Yahoo page) Historical quotes are downloaded from Historical Prices page. For example MSFT current quote page is here:ĪmiQuote uses rather “download data” link which is: īut it is not relevant because both show same current quote.
There are a couple of things you need to know about Yahoo Finance pages that AmiQuote uses to download “historical” and “current” quotes.Ĭurrent quotes are quotes for current day (or previous day if there is no trading session today).
