McClellan Summation Index [LazyBear]

McClellan Summation Index is a breadth indicator derived from McClellan Oscillator (

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/below zero. 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.

Indicator uses the advancing/declining stocks from NYSE by default, but you can change them to any market in the options dialog.

Hi Lazy Bear,

I'm new to this site and I have a few support tickets out without reply.

I am looking for the McClellan OSC to run on NYSE and Nasdaq.

I don't know where to find the OSC or the legends for either market

Could you or anyone who sees this please help ?

Thanks much

Do not agree. In the long run is not stable. Ii has to be optimized. Low Freqency Trading indicator. When not optimized the parameters basket (19,39) gives low profits and make the traders send margin calls quite often. But - give a try with walking signal line. In fact it helps in search of the Grail.
Thank you!!!!! I no longer have to go to their site to get their choppy chart!
