Heikin-Ashi
Quick Definition
A modified candlestick charting technique that uses averaged price data to filter out market noise and make trends easier to identify.
Key Takeaways
- Heikin-Ashi uses averaged price data to smooth candles and highlight trends more clearly than standard charts.
- Strong trends show candles without shadows on one side; indecision shows small bodies with shadows on both sides.
- Do not use HA prices for actual trade entries — they are averaged and differ from real market prices.
What Is Heikin-Ashi?
Heikin-Ashi (Japanese for "average bar") is a candlestick charting technique that modifies the standard OHLC (open, high, low, close) values using averaged formulas to create smoother-looking candles that better highlight trend direction. The Heikin-Ashi close is the average of the open, high, low, and close of the current period. The open is the midpoint of the previous Heikin-Ashi candle's body. The high is the maximum of the current high, HA open, or HA close, and the low is the minimum of the current low, HA open, or HA close. This averaging produces distinctive visual patterns: strong uptrends appear as consecutive green candles with no lower shadows, strong downtrends as consecutive red candles with no upper shadows, and indecision/reversal as candles with small bodies and long shadows on both sides (spinning tops). Heikin-Ashi charts are excellent for staying in trends longer and avoiding premature exits from whipsaws. However, because prices are averaged, the candles do not reflect actual market prices — traders should use standard charts for precise entry and exit levels while using Heikin-Ashi for trend direction.
Heikin-Ashi Example
- 1Switching to Heikin-Ashi revealed a clean sequence of 14 consecutive green candles with no lower shadows — a clear sign of a strong uptrend that standard candles obscured with their daily volatility.
- 2The appearance of small-bodied Heikin-Ashi candles with long shadows on both sides after a long downtrend signaled indecision, and the trader prepared for a potential reversal.
