Hi Matt Chao,
I use interactive brokers, but it only have time base chart, so instead 70T i used a 5sec chart to improvise. Not sure if that's a good idea.
Hi, Frost. Welcome to the forum. I actually don't use my broker's feed but pay for a data feed separately. I use Kinetic/Ninja Trader but most of the guys on the forum (including Volman) use ProRealTime.com. Certainly the principles in this method apply to more than just the 70T chart, but I'd recommend checking out Bob's first book to find out more. It's a pretty easy read compared to many price action books.
