Oscillator is difference between Arron Up and Down. Oscillator makes it easier to see which of the two indicators are stronger. Normally is plotted with the two distinct lines. This indicator fluctuates between -100 and +100 with 0 as the mid line. When oscillator is positive there tends to be upward trend bias, and downward trend bias when this oscillator is negative. The default value for this oscillator is 25, while is 14. Because of the way was designed there are no divergences in this indicator.
Another usage of Oscillator would be to see when any value of > 90 or < -90 occurs. This may signal a strong trend may be ready to occur. With a 90 move it is considered until there is a move of -90. The same is true for move below -90. It is until a move above 90 is reached.
Of course as with all indicators using more than one is recommended to get clearly signals.
