NYSE McClellan Oscillator
Nasdaq Summation Index
When we talk about the McClellan Summation Index, we are usually referring to the version of it calculated on NYSE Advance-Decline (A-D) data. But it can be calculated on any type of breadth data. Whether such an alternative is useful is a separate question.

Market Breadth Data Notes
- We use WSJ/Barron's data for our final breadth numbers. Calculations made on numbers from other sources will show a slightly different result.
- We wait until late in the day in order to have access to the "final" numbers.
- This reflects final readings for the indicators covered.
- Values for indicators calculated using preliminary numbers released just after the close usually differ slightly from these numbers.
- We usually recommend that readers keep their own data for themselves, but this is a useful way to check and see if your numbers agree with ours.
