McClellanOsc2.efs – EFS

McClellanOsc2.efs

File Name: McClellanOsc2.efs

Description:
McClellan Oscillator with user defined options for displaying the indictor as a cumulative summation index. The moving average calculation can be set to use simple or exponential. The oscillator is colored green when the slope of the oscillator is positive and red when negative. The plot type can be set to "Line" or "Histogram."

Formula Parameters:
MA Type: Exponential [Exponential, Simple]
Summation: On [On, Off]
Positive Slope: Green
Negative Slope: Red
Plot Type: Histogram [Line, Histogram]

Notes:
NA
