What Is the McClellan Summation Index?
Developed by Sherman and Marian McClellan, the McClellan Summation Index is a breadth indicator derived from the McClellan Oscillator, which is a breadth indicator based on Net Advances (advancing issues less declining issues). The Summation Index is simply a running total of the McClellan Oscillator values. Even though it is called a Summation Index, the indicator is really an oscillator that fluctuates above and below the zero line. As such, signals can be derived from bullish/bearish divergences, directional movement and centerline crossovers. A moving average can also be applied to identify upturns and downturns.
