Bill Williams Indicators | Chaos Theory


To understand the overall structure of the market B. Williams advised to analyze the market through the following five dimensions:

  • Fractal (phase space)
  • The driving force (energy phase)
  • Acceleration / deceleration (power phase)
  • Zone ( combination of strength / power phase)
  • Balance Line

For understanding and analyzing these dimensions there have been established a number of indicators.

AC Indicator - Accelerator Oscillator

The Accelerator Oscillator indicator helps traders spot shifts in market momentum before price itself confirms the move. Developed by Bill Williams, it measures acceleration and deceleration of the driving force behind a trend. This guide explains what the indicator is, how to trade with it, its formula, and where to apply it.

Williams Alligator Indicator

Bill Williams introduced the Alligator indicator almost three decades ago in 1995. But it is still a very popular indicator in trading circles.

Awesome Oscillator - AO Indicator

The creator of the Awesome Oscillator, as well as several other indicators and oscillators, is the famous trader Bill Williams. In fact, the AO was a kind of addition to the Williams Alligator - another “invention” of Bill Williams, and the MACD mechanism was adopted as the basis for its creation, albeit with significant changes.

Williams Fractal Indicator

Bill Williams' Fractals are formed around a group of five consecutive bars the first two of which are successively reaching higher (or diving deeper) and the last two descending lower (or growing higher) with the middle one being the highest (or the lowest) result in the group accordingly.

Gator Oscillator

The Gator Oscillator turns Bill Williams' Alligator indicator into an easy-to-read histogram that reveals when a market is trending strongly or moving sideways. Traders use it to confirm trend strength, spot consolidation phases, and time entries with greater confidence. This guide covers what the Gator Oscillator measures, how it's built, and practical steps for applying it on MetaTrader and NetTradeX platforms.

Market Facilitation Index indicator

The Market Facilitation Index indicator measures how efficiently price moves relative to trading volume, revealing when a trend has genuine strength or is quietly running out of steam. This guide explains what MFI is, how to read its four market phases, how to calculate it, and how to apply it directly on your trading platform.
