What is the Heiken Ashi Oscillator?

The Heiken Ashi Oscillator is a technical indicator widely used in the forex market to identify trends and potential reversal points. It is derived from the Heiken Ashi candlestick charting technique, which tries to aim to filter out market noise and provide a smoother representation of price action.
Unlike traditional candlestick charts, the Heiken Ashi candles are calculated based on average price values, resulting in a visually distinct charting style. The Heiken Ashi Oscillator is derived from these modified candles and further tries to enhance their usefulness by providing a separate indicator that oscillates above and below a zero line.
The oscillator consists of positive and negative bars that represent the difference between the open and close prices of the Heiken Ashi candles. Positive bars indicate bullish momentum, while negative bars suggest bearish momentum. Traders can observe the oscillator’s movements to gauge the strength and direction of the prevailing trend.
Additionally, the Heiken Ashi Oscillator is effective in spotting potential trend reversals. When the oscillator reaches extreme levels and starts to change direction, it may signal an impending shift in market sentiment. Traders often look for divergences between the oscillator and price action to identify possible trend reversals or the weakening of an ongoing trend.
