Accelerator Oscillator (AC) belongs to the group of oscillators, is an indicator of the deceleration or acceleration of the driving force of the traded asset.
The creator of this indicator is a well-known trader and author of a number of books on stock trading Bill Williams. Accelerator Oscillator is based on the principle of increasing or decreasing the speed of price movement. When reversing the price movement, the speed will slow down, and the development of market movement increases and the acceleration of prices. Noticing the peculiarities of the change in the rate of price, Williams developed an indicator to recognize this change to use such features to determine the points of opening and closing of trading positions.
