The Stochastic Oscillator was introduced by Dr. George C. Land in the 1950s. The Stochastics oscillator finds the range between an asset’s high and low price during a given period of time. The current securities price is then expressed as a percentage of this range with 0% indicating the bottom of the range and 100% indicating the upper limits of the range over the time period covered. The idea behind this indicator is that prices tend to close near the extremes of the recent range before turning points.
