What is The McClellan Oscillator?

Developed by Sherman and Marian McClellan, the McClellan Oscillator is a breadth indicator derived from Net Advances, the number of advancing issues less the number of declining issues. Subtracting the 39-day exponential moving average of Net Advances from the 19-day exponential moving average of Net Advances forms the oscillator. As the formula reveals, the McClellan Oscillator is a momentum indicator that works similar to MACD. McClellan Oscillator signals can be generated with breadth thrusts, centerline crossovers, overall levels and divergences.
