No offense but this thread must be a joke. In your other thread you just started you claim how lagging indicators are so useless, and yet here, you say you plan to trade CL (meaning you don't even trade), you ask about how to set your range bars (meaning you haven't even tried anything for yourself yet), you say you don't even have a computer yet, you put down people using charts (hence why ask about range bars to begin with), and you have no experience with anything.
My god, seriously, this must be a joke. You sound so sure about the benefits of order flow, so much so that you feel you can bad mouth charts and indicators, and yet everything else you say makes you sound like a total amateur.
I don't mean to be rude, but there are some major issues with your thought process.
