Hey all, I've been looking at PnF charting for a while now, but I've spent the last 10 days really getting into it to see if it has value. One of the most useful sites I've found for PnF charting is Stockcharts.com - and they offer the ability to define box size by ATR - which seems like a very solid approach rather than using, say, a number of dollars or % in a stock (feedback appreciated on that as well). What do people think about this approach? Are you using ATR or more traditional methods? Or have you found PnF charting more or less useful than, say, Renko charting? Thoughts appreciated!
