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.
