Accelerator Decelerator Oscillator
The Accelerator Decelerator Oscillator by Bill Williams manipulates multiple moving averages of the midpoint price and displays the result with movable guides on a bi-color histogram. The user may change the input (midpoint), method (SMA) and periods lengths. This indicator’s definition is further expressed in the condensed code given in the calculation below.
How To Trade Using Accelerator Decelerator Oscillator
Adjust the top and bottom guides to control the quantity and quality of the trading signals. If the ado peaks above the top guide a sell signal will be generated. Conversely, if the ado troughs below the bottom guide a buy signal will be given.
