I'm doing ok making a living off the market without charting, and know serveral more who do the same. I'm always amazed at the number of people who think their way is the only way.
Forst of all, this board has enogh info to make anybody successful trader, but it needs to be pieced together. Trading without charts is easy, insider info.
Very rarely look at charts and never use them for trading decisions. All you need is recent and historical price action in percentages. My autotrader can't read charts. The market may show randomness, but people always trade the same over the years (IOW they make bad decisions that a few of us can use for profits). Good trading to all.
