The actual price movement is as precise as can be. Indicators, by design, less so. So why handicap yourself and settle for a tool that is simply derived from the price movement?
I look at price movement as being the heart, and indicators the pulse. And I would rather have the doctor listen to my heart than just feel my pulse!
But on the other hand, if you can't read the price movement, indicators may be your only choice.
You don't want to "think" while trading. You want to recognize and act. If indicators help that recognition, use them, if they impair, don't use them. "Thinking" is for analysis and development.
