Supposedly, stockcharts.com offers free BATS real time charts. I am unable to figure out how to bring up an intraday chart there. http://support.stockcharts.com/entries/102352-how-do-your-bats-real-time-charts-work Please tell me how to do it. Thank you.
Just found out that to access intraday charts I have to sign up for the Basic or Extra service at $15 or $25 a month: http://stockcharts.com/sales/new.html
I'll second that. They offer Renko charts, which I haven't seen in many places at this price level. Also, if you want BATS stuff for free, look up freestockcharts. They use a BATS feed. You've got to put up with ads, but the charts are actually quite impressive.
