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.
La idea en pocas palabras
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.
Cómo se calcula
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)Cómo usarlo
- 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.
Sacar conclusiones
- A colour change is the earliest warning of a shift in momentum.
Ejemplo
During a pullback in an uptrend AC prints two consecutive green bars above zero: momentum is accelerating up again.
Los precios de los ejemplos son ilustrativos.
Ten cuidado con
- Early signals are also more often wrong; wait for confirmation from price.
