Quote from Buy1Sell2:
I use BB. The argument against BB is that it shows nothing that isn't already in the price action. That point has some merit. My argument for it is that it helps me "see" the action in the chart better. When it's hugging the line, it's not time to reverse yet etc. I think it's a great tool , just as the lines on a highway help me to drive my car in a safe way. Without the lines on the highway, I may drive more recklessly.
