Heikin Ashi Charts: Smoothing Out Price Action
The Logic of the Average Bar: What is Heikin Ashi?
Developed by Munehisa Homma in the 1700s, the Heikin Ashi (Japanese for 'average bar') chart is a modified version of the standard candlestick chart. While standard candles only show the open, high, low, and close of a single period, Heikin Ashi candles use a mathematical average of the previous period's performance.
This mathematical smoothing is designed to eliminate 'false' candles that often appear in volatile markets. Heikin Ashi charts make trends much easier to identify by visually grouping candles of the same color, allowing you to stay in winning trades longer without being 'shaken out' by minor price fluctuations.
The Formula: 4 Essential Calculations
Each Heikin Ashi candle is calculated using the following formulas:
- Close: (Open + High + Low + Close) / 4 (Average price of the current bar).
- Open: (Open of previous bar + Close of previous bar) / 2 (The midpoint of the previous bar).
- High: Max (High, Open, Close).
- Low: Min (Low, Open, Close).
Because the 'Open' of the current bar is the midpoint of the previous one, Heikin Ashi candles always look like they are 'starting' from the middle of the previous candle, creating a smooth visual transition.
Heikin Ashi Entry Checklist
Entry: Long on first green candle after a red series
Strength: Hold if candles have no lower wicks
Weakness: Exit or scale out if both wicks appear
Confirmation: Align with a 20 SMA for trend filter
Stop-Loss: Use the 'Real' price from standard candles
Targets: Reach the next major support/resistance level
Strategy: Decoding the Wicks for Trend Strength
Strong Uptrend: Characterized by a series of long, green candles with no lower wicks. This indicates that the bulls are in complete control of the momentum. Weakness: If small wicks begin to appear on both sides of the candle, it signals that the market is entering a state of 'Indecision'. Reversal: A small-bodied candle with long wicks on both sides (similar to a Doji) often precedes a major change in trend direction. Professional traders wait for the color to flip and for a 'One-Sided Wick' candle to confirm the new regime.
Warning: Lag and Stop-Loss Management
The biggest advantage of Heikin Ashi—smoothing—is also its biggest drawback: lag. Because the price on the chart is an average, it is not the current market price. Always check the 'Real' price on a standard candle chart before placing your stop-loss or profit target, as they may differ significantly from what you see on the Heikin Ashi bars.
