A trader friend of mine laughed when I told him that I concentrated more on oversold and overbought levels, to him, those concepts were far too simple for it to be able to yield any profit in trading. He was putting his focus on complex things because to him, your strategy has to be as complex as the charts look. While he is still struggling to understand those complex concepts surrounded by many noise, people with the simpler strategies that are straightforward to understand are making progress already with their trades and having positive returns.
