Double Mcclellan Oscilator

Plots two Mcclellan Oscillators.

First MCO is plotted as the histogram using traditional n values of 19 and 39. Histogram is green when the oscillator is greater than 0.

Second MCO is plotted as the lime green and pink line. N values for the second oscillator should be lower than the first so that it has a shorter window length.

Advance/decline can be calculated using NYSE or NASDAQ stocks.
