//  The McClellan Summation Index is a market breadth indicator developed by
//  Sherman and Marian McClellan. It is a long-term version of the McClellan
//  Oscillator and its interpretation is similar to that of the McClellan
//  Oscillator except that it is more suited to major trend reversals. For more
//  extensive coverage of the index refer to the book Patterns for Profit, by
//  Sherman and Marian McClellan. McClellan suggests the following rules for
//  use with the summation Index: Look for major bottoms when the Summation
//  Index falls below -1300. Look for major tops to occur when a divergence
//  with the market occurs above a Summation Index level of +1600. The
//  beginning of a significant bull market is indicated when the Summation
//  Index crosses above +1900 after moving upward more than 3600 points from
//  its prior low (e.g. the index moves from -1600 to +2000). The summation
//  index is plotted by adding the Cum function to the McCllellan Oscillator.
