You apparently did not read my reply at all. Re-read it Hint: it does not matter what symbol you use.
Also that is NOT really AmiQuote question. AmiQuote is web browser. It downloads what is on the web site. WYSIWYG. You don’t ask Mozilla when site say ABC updates their server. You should contact data vendors / web site owners if you have doubts about when they update their servers.
As for Stooq.pl and other services if you have doubt, GO TO THEIR WEB PAGE, example:
You will get EXACTLY THE SAME data from AmiQuote.
AmiQuote works exactly THE SAME as web browser (IE, Firefox, Chrome, Opera).
What you see on the web page is what you get.
