Sometimes indicators just don't work. Typically, it takes a little more than looking at a chart with the default settings of an indicator to be a successful trader.
|In Figure 1 we have a daily chart of Kraft (KFT). Like almost all stocks, it is higher than it was at the March 2009 bottom. Many traders use stochastics to identify trading opportunities, and KFT was oversold on this indicator at the bottom and gave a timely buy signal. The stock moved higher in May and the stochastics confirmed the price action. Unfortunately, prices soon fell. Near the September top, the stochastics successfully highlighted a bearish divergence.|

|This is typical of the experience of new technicians. Sometimes an indicator works as advertised and at other times it doesn't. In the lower clip, we see the relative strength index (RSI) with a moving average superimposed. Here the idea is to sell if the indicator falls below the moving average.|
|Using that idea, we would not have been led astray by the confirmation in stochastics and would have been out of the long position a few days early when stochastics set up a divergence.|
|The bottom line is that trading is difficult. Using indicators just like the book says to will rarely lead to profits over the long term. Understand what the indicator is designed to do, and then look at how you can modify that to fit your style. In this case, stochastics is actually a slow version of momentum. The RSI is a faster measure of that. Applying the moving average to the RSI lets you see what very few others are, and that could be your trading edge.|
