Are there any web sites where I can type in a symbol name and get statistics in terms of what percentile a given day's volume is at a certain time in the day? So for example, say XYZ trades 10 million shares on average by 12PM. On the day I go to the web site, XYZ traded 1000 shares. So the site tells me I'm at the 1st percentile. Another day I go there, and XYZ has traded 500 million shares by 12PM, I find out that I'm in the 99th percentile in terms of volume. I guess I could build something like this myself. Just hoping I don't have to.
