McClellan Oscillator [LazyBear]

Developed by Sherman and Marian McClellan, the McClellan Oscillator is a breadth indicator derived from Net Advances, the number of advancing issues less the number of declining issues. Subtracting the 39-day exponential moving average of Net Advances from the 19-day exponential moving average of Net Advances forms the oscillator.

As the formula reveals, the McClellan Oscillator is a momentum indicator that works similar to MACD .

McClellan Oscillator signals can be generated with breadth thrusts, centerline crossovers, overall levels and divergences.

I have added the following options:
- Can choose Advancing/Declining issues of any market. Default is NYSE.
- Can show the EMAs and/or oscillator.
- Ratio Adjusted Calculation mode (as explained in the stockcharts link below) or default mode.
- Can use custom timeframe. Default is chart timeframe.

Hi Good People,

How about if we want to chart the Advancing & Declining Volume(s) instead of Issues ?

ADVN / DECN is only for the NYSE. Did you happen to have the advance decline for the Nasdaq composite and Index?

For NASDAQ, use ADVQ / DVCQ

If you type "Advancing" or "Declining" in the symbol box, it should list the names for other mkts too.

Great thanks, I just searched for it. I used stockcharts for all these. Now, I can code some setups, that works..

Hi Lazybear,

i reckon there is another one called, McClellan Summation index?
Can both these be used on stock, i thought it is more suitable for indices? Thanks

Hi,

I can talk for the calculation part, will leave the proper usage and potential usecase scenarios to more experienced traders. :)

This is a breadth indicator, so makes use of the advancing/declining issues for a given market and not based on a single stock. AFAIK, SummationIndex is nothing but a running sum of McClellan oscillator.

BTW, I will publish the summationindex too today.
