I agree with most all of what oldrader is saying. I went from being an intuitive trader with good feel and no discipline, to an indicator laden, confused zombie, with no feel and still no discipline. The obvious problem with stoh's and RSI is that the more over bought/sold the market becomes. the more your "system" has you committed to the wrong side of what can be the biggest moves ever, Any idea how oversold SP was the Friday before the 1987 crash. If I could only use a single technical study it would be MA's. Yeah choppy markets suck, but I fade movement as a habit, so for my personality, having something that counters my personal trading biases is appropriate. But oldtrader IMO makes a great point that trading indices is more about identifying what the componants are trying to do. ES is'nt a single entity. but a sea of issues, some leading. some following, some lagging, but in the end painting a mosaic of overall market structure and direction. remember the old saying, it's not a stock market, but a market of stocks.
