Accelerator Oscillator Signals and Trading-System Rules

Summary

This article introduces Bill Williams' Accelerator Oscillator (AC), a momentum measure calculated as the Awesome Oscillator minus its short moving average. It explains the indicator's zero line as a directional reference and gives simple rule sets: readings above or below zero imply bullish or bearish conditions, while values beyond the recent range are treated as stronger or weaker momentum. A further setup combines those range comparisons with closing price relative to a 50-period exponential moving average to produce buy and sell signals.

The article outlines how to turn the rules into an automated MQL5 tool that reads the indicator buffer and reports values or signals on a chart. The proposed rules are educational examples, not evidence-backed strategies: no backtest results, transaction costs, or risk controls are presented in the supplied text. A zero-line or recent-extreme signal can lag, whipsaw, or behave differently across instruments and timeframes. The author explicitly recommends testing the rules before live use.

Key ideas

• The Accelerator Oscillator subtracts a short moving average of the Awesome Oscillator from the oscillator itself.
• Values above or below zero are used to classify bullish or bearish momentum conditions.
• Comparing the current value with recent highs and lows creates simple momentum-strength signals.
• Combining recent AC extremes with price relative to a 50-period EMA defines example entry conditions.
• The article shows how to automate signal reporting in MQL5 but supplies no performance validation.
