Stochastic
It was published in the 1950s by Dr. George Lane and is still in wide use to this day. It is helpful to generate overbought and oversold trading calls, a 0-100 bounded range of values. Stochastic oscillators are sensitive to momentum rather than absolute price. The trading signal used when there is a divergence-convergence in the indicator.
It follows the speed or the momentum of price. As a rule, the momentum changes direction before price.” As such, bullish and bearish divergences in the Stochastic Oscillator can be used to foreshadow reversals.
As an oscillator, the Stochastic Oscillator it makes easy to identify overbought and oversold levels. The oscillator ranges from zero to one hundred. It’s not matters how quickly security advances or declines; the Stochastic Oscillator will always fluctuate within this range. Traditional settings use 80 as the overbought threshold and 20 as the oversold threshold. These levels can be adjusted to suit analytical needs and security characteristics. Readings above 80 for the 20-day Stochastic Oscillator would indicate that the underlying instrument was trading near the top of its 20-day high-low range. Readings below 20 occur when an Instrument is trading at the low end of its high-low range. Generally, traders take overbought level (80-level) as selling securities and oversell level (20 - level) as buying securities.
