Heikin-Ashi, a Japanese term meaning average bar or average pace, is a type of price chart that uses averages to show the price movement of an asset. Unlike traditional candlestick charts, Heikin-Ashi charts offer a smoother representation of market trends, filtering out short-term fluctuations and emphasising prevailing price direction. This technique is achieved by employing a formula that calculates each candlestick's open, high, low, and close based on the average prices of the previous candle. The Heikin-Ashi formula uses the previous candle's prices to calculate the current candle's prices. This results in a smoother appearance than regular candlestick charts, making it easier to identify trends and potential reversals.
| Characteristics | Values |
|---|---|
| Open | Open of previous bar + Close of previous bar / 2 |
| Close | Open + High + Low + Close of current bar / 4 |
| High | Maximum value from High, Open, or Close of the current period |
| Low | Minimum value from Low, Open, or Close of the current period |
| Wick | The top of the upper wick is the highest value on the candle |
| Wick | The bottom of the lower wick is the lowest value on the candle |
| Colour | Red or black = downtrend; Green or white = uptrend |
| Time series | Defined by the user, e.g. daily, hourly, or five-minute intervals |

What You'll Learn
Calculating the open
The open of an HA candlestick is calculated as the midpoint of the previous candlestick. Specifically, it is the average of the previous candlestick's open and close prices. This can be calculated using the formula:
Open = (Open of the previous candlestick + Close of the previous candlestick) / 2
This formula is used to determine the open for the current period. By starting each new candlestick at the middle of the previous one, the HA chart presents a smoother appearance compared to regular candlestick charts. This smoothing effect makes it easier to identify trends and potential reversal patterns.
It is important to note that HA charts use data from both the current and previous sessions to derive their values. This means that the open of the current HA candlestick will always be between the open and close of the previous candlestick. This calculation method is a key distinction between HA charts and traditional candlestick charts, which typically represent the open, high, low, and close prices within the current time period.
The open value of an HA candlestick is crucial for understanding the overall trend. For example, a long-bodied green HA candle with no lower wick indicates a strong upward trend, while a long-bodied red HA candle with no upper wick suggests a strong downward trend. Traders can use these signals to make informed decisions about entering or exiting trades.

Calculating the close
Heikin-Ashi charts are a valuable tool in technical analysis, smoothing out price action and making it easier to spot trends and reversals when trading. They are similar to traditional Japanese candlestick charts, but the open and close are calculated differently.
Each Heikin-Ashi candle has an open, close, high, and low. The open of a Heikin-Ashi candlestick equals the midpoint of the previous candle, so every new candlestick starts from the middle of the previous one. This is calculated as: Open = (Previous Open + Previous Close) / 2.
The close of a Heikin-Ashi candlestick is calculated as an average of the open, high, low, and close prices of the current period. The formula for this is: HA-Close = (Open (0) + High (0) + Low (0) + Close (0)) / 4.
The body of the candlestick represents the difference between the session's open and close prices. If the candle is green, the closing value is greater than the opening value, and is represented at the top of the body. If the candle is red, the closing value is lower than the opening value and is represented at the bottom of the body.
It is important to note that Heikin-Ashi charts do not reflect real-time prices as they take an average, so the current price of the candle may not match the price at which the market is actually trading. For this reason, some charting platforms show two prices on the Y-axis: one for the calculation of the Heikin-Ashi and another for the current price of the asset.

Calculating the high
The Heikin-Ashi (HA) candlestick is a trading tool used by technical traders to smooth out candlestick patterns, making it easier to identify trends and make trading decisions. It is a type of Japanese trading indicator and financial chart that means "average bar".
To calculate the high of a Heikin-Ashi candlestick, you need to find the maximum value of the current period's Heikin-Ashi high, open, or close. In other words, the "high" of a Heikin-Ashi candle is the highest value of the recent high, open, or close.
High = Maximum of High, Open, or Close (whichever is highest)
This means that the "high" of the Heikin-Ashi candle is determined by taking the highest value of the current period's high, open, or close. For example, if the current period's high is $100, open is $90, and close is $110, then the high of the Heikin-Ashi candle would be $110, as it is the highest value among the three.
It is important to note that the Heikin-Ashi high is different from the traditional Japanese candlestick high. The Heikin-Ashi high is calculated using the average of the current and previous sessions' data, while the traditional Japanese candlestick high represents the highest price within the current time period. By taking an average, the Heikin-Ashi chart provides a smoother representation of price trends, filtering out the "noise" of day-to-day price fluctuations.

Calculating the low
The "low" value of an HA candlestick represents the lowest price point of a specific period. It is calculated by taking the minimum value from the low, open, or close of the current period. In other words, it is determined by finding the lowest value among the lowest shadow, the open price, or the close price of the current period.
To illustrate this with an example, let's consider a scenario where we are analysing the price movement of a particular stock over a one-day period. The stock opened at a price of $100, reached a high of $110 during the day, but then closed at a price of $95. In this case, the "low" value for the HA candlestick would be $95, as it represents the lowest price point of the period.
It is important to note that the "low" value of an HA candlestick is not simply the lowest price within the period but is influenced by the open and close prices as well. This is a key distinction from traditional Japanese candlestick charts, where the "low" typically refers only to the lowest price reached during the specified time frame.
The calculation of the "low" value in HA candlesticks contributes to the smoothing effect that these charts provide. By considering the open and close prices in addition to the period's lowest price, short-term fluctuations are minimised, and the prevailing price direction is emphasised. This smoothing effect helps traders identify trends and potential reversal patterns more easily, making HA candlesticks a valuable tool in technical analysis.

How to read the chart
Reading a Heikin-Ashi (HA) chart is a valuable tool for traders and investors who want to identify trends and potential reversal patterns in financial markets. Here's how to read an HA chart:
Understanding the Basics
The HA chart is a type of price chart that uses averages to smooth out price movements and show the overall trend of an asset's price movement. It is constructed like a regular candlestick chart, but the formula for calculating each bar is different. Each HA candlestick displays four different price levels: the lowest point, the highest point, and open and close prices. However, unlike traditional candlestick charts, HA candlesticks use data from the current and previous sessions to derive their values.
Interpreting Colours and Wick Presence
On an HA chart, up days are usually represented by empty or white/green candles, indicating an uptrend. Conversely, down days are represented by filled or red/black candles, signalling a downtrend. The presence of a wick on an HA candle is also significant. The emergence of an upper wick, for instance, suggests that a downtrend might be losing momentum, while the appearance of a lower wick indicates that an uptrend may be losing its bullish momentum.
Calculating Open, Close, High, and Low
The HA formula is used to calculate each candlestick on the chart. Here is a simplified version of the formula:
- Open = (open of the previous bar + close of the previous bar) / 2
- Close = (open + close + high + low of the current bar) / 4
- High = the maximum value from the high, open, or close of the current period
- Low = the minimum value from the low, open, or close of the current period
Identifying Trading Signals
HA charts provide five primary signals that help identify trends and buying opportunities:
- Hollow or green candles with no lower "shadows" indicate a strong uptrend.
- Candles with a small body and upper and lower shadows indicate a potential trend change.
- Long red candles with small lower wicks at the start indicate a strong downtrend.
- The emergence of longer lower wicks during a downtrend suggests buying pressure is starting to build.
- Small candles with shadows on both sides indicate indecision in the market.
By understanding these signals and interpreting the smoothed-out trends on an HA chart, traders can make more informed decisions about entering or exiting trades.

Frequently asked questions
The Haikin-Ashi formula uses the previous candle's prices to calculate the current candle's prices. The formula is as follows:
- Haikin-Ashi close = (open + high + low + close) / 4
- Haikin-Ashi open = (previous Haikin-Ashi open + previous Haikin-Ashi close) / 2
- Haikin-Ashi high = maximum value of high, open, or close
- Haikin-Ashi low = minimum value of low, open, or close
The Haikin-Ashi chart is constructed like a regular candlestick chart, but the formula for calculating each bar is different. The Haikin-Ashi formula uses averages to smooth out price movements, making it easier to identify trends and potential reversals. This can be particularly useful for trend traders who want to identify the direction of the trend and enter trades accordingly.
The Haikin-Ashi technique is a valuable tool in technical analysis, used to decipher market trends and predict future price movements. It can help traders make more informed decisions by smoothing out price fluctuations and filtering out short-term market noise. For example, a long-bodied green Haikin-Ashi candle with no lower wick is considered indicative of a strong upward trend. Conversely, a red candle suggests a downtrend, indicating that selling pressure is dominating.
