IS there a site that records the biggest winners and losers each day for the whole week? I mean I know there are sites like barchart.com, finance.yahoo.com; etc that show the biggest winners and losers for one day. But i want an overview of the whole week... and on each day of the week the biggest winners and losers. can anyone help tell me where I might find this information? THank you. Actually better yet. Are there any sites that record all the stocks that gapped up and gapped down for the week? I would hope that I could get this info for free. thank you.
