Look at the chart in MO today (10/17). The big move was entirely within the trading day. As opposed to a stock opening down 10 and just staying there. This second example seems less useful for traders. Can everybody agree on that? The first example is called an "Intraday" mover. I'm asking where to get a list of these stocks. Even a list of these stocks posted after the close, to get me started on this topic.
Makes sense. You're gonna need a screener of sorts then. I think I have the Trade-Ideas Pro demo on my system still, I'll see if it can do that for you. - The New Guy Edit: Nvm, accout has expired. I'll keep looking though...
http://www2.barchart.com/default.asp If you look at links on left on that page it will give you point movers, volume movers, percent movers. It also gives delayed intra day movers.
