Normally, stock with a stochastic oscillator number above 80% is considered to be “overbought” and stock that gives a number below 20% is “oversold.” When the stochastic oscillator moves from below to above 20%, this can be taken as a signal to buy stock. Likewise, when the stochastic number falls from above to below 80%, this can be taken as a sell signal. Some traders additionally use a crossover strategy, which basically is where buy signals are triggered when %K crosses over %D, and sell signals are given when %K crosses below %D. This produces many false symbols and is less common in today’s trading world [4].
