The McClellan Summation Index is simply a cumulative indicator of the McClellan Oscillator. It also can be interpreted as bullish or bearish when it crosses over the zero line. We find crossovers on a 10- or 20-day moving average of this indicator to make for a great trend following system. It tends to get you into trends early and keep you in…very few whipsaws.

Note: Scaling must be set to Arithmetic for the chart to be displayed properly.
