<i>Once you have all this data, simulate mouse clicks on the next and previous buttons to paginate and get more data. It’s all a tricky process, very hacky, but you’re getting really valuable data.</i><p>If you go all the way to simulate mouse clicks, why not OCR the prices off the screen? I guess that's somewhat simpler (I used to do it for a poker bot, there's a few open source screen scraping tools available). Maybe there's more information available in memory than is shown to the user, of course.
