McClellan Oscillator is the difference between two exponential moving averages of
the advance decline spread. The time periods are typically 19 and 39 days. The values
of the indicator oscillate around zero, and generally range from -100 to +100. Overbought/oversold
conditions are found above +70 and below -70. Values above +100 or below -100 indicate
the continuation of the current trend. Buy/sell signals are generated by zero line
crossovers.
McClellan Oscillator and McClellan Summation were developed by Sherman and Marian
McClellan.
