SMOOTHING THE OSCILLATOR eliminates many of the false wiggles. It is normally accomplished through a simple moving average, but can also be done with an exponential average or another oscillator. Once smoothed, upturns and downturns in an oscillator often become tradable, or can become part of a pattern.
LEVELS THAT ACT AS BUY OR SELL LINES can also eliminate some of the false turns in an oscillator, and often indicate levels at which tops and bottoms can be expected in an oscillator, a smoothed oscillator, or Detrend. A Level is an oscillator level that is frequently exceeded as oscillators make highs and lows, such as the 70 and 30 levels of the stochastic or the 100 and -100 levels of the CCL Those levels are built into the oscillator; others can be determined by observation.
