Bill Williams indicators
Accelerator Oscillator (AC)
Shows whether the market's driving force is speeding up or slowing down, often before the price changes direction.
用通俗的话解释
Bill Williams' view: before the price turns, momentum changes; and before momentum changes, its acceleration does. AC measures that acceleration as the difference between the Awesome Oscillator and its own average.
计算方法
Awesome Oscillator minus its 5-period simple average. Bars are green when AC rises, red when it falls.
AC = AO − SMA(AO, 5)
AO = SMA(median price, 5) − SMA(median price, 34)如何使用
- Two green bars in a row above zero (or three below zero) are Williams' buy signals; the reverse for sells.
- Use it to time entries in the direction of the Alligator's trend.
得出结论
- A colour change is the earliest warning of a shift in momentum.
示例
During a pullback in an uptrend AC prints two consecutive green bars above zero: momentum is accelerating up again.

注意事项
- Early signals are also more often wrong; wait for confirmation from price.
