Heikin-Ashi, sometimes spelled Heiken-Ashi, is a type of price chart that uses averages to show the price movement of an asset. The Heikin-Ashi formula for calculating the prices is as follows: Average price = (open + high + low + close) / 4. The open of a Heikin-Ashi candlestick equals the midpoint of the previous candle, while the close equals the average value between the open, high, low, and close. The high and low take the actual high and low of the period, respectively. The Heikin-Ashi chart is constructed like a regular candlestick chart, but the formula for calculating each bar is different, resulting in a smoother appearance.
| 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 | Top of the upper wick is the highest value on the candle |
| Wick | Bottom of the lower wick is the lowest value on the candle |
| Colour | Red if the closing value is lower than the opening value |
| Colour | Green or white if the closing value is higher than the opening value |
| Body | Longer body indicates a stronger trend |
| Body | No upper wick on a red candle indicates a strong downward trend |
| Body | No lower wick on a green candle indicates a strong upward trend |
| Body | Small body with upper and lower wicks indicates indecision |

Heikin-Ashi open calculation
Heikin-Ashi charts are a type of price chart that uses averages to show the price movement of an asset. They are constructed similarly to regular candlestick charts, but the formula for calculating each bar is different. The Heikin-Ashi technique averages price data to create a Japanese candlestick chart that filters out market noise, making it easier to spot trends and reversals.
The Heikin-Ashi open is calculated as the midpoint of the previous candle. The formula for the open is:
> Open = (Open of the previous candle + Close of the previous candle) / 2
This means that each new candlestick on the Heikin-Ashi chart starts from the middle of the previous candle. By calculating the open in this way, the Heikin-Ashi chart incorporates the previous period's price information, resulting in a smoother appearance and a clearer overall trend.
The open value is just one part of the Heikin-Ashi formula, which also includes the high, low, and close values. The high and low values are determined by the highest and lowest values of the current period, respectively, and can include the shadows, open, or close values. The close value is calculated as the average of the open, high, low, and close of the current period:
> Close = (Open + High + Low + Close of the current period) / 4
Together, these calculations result in a Heikin-Ashi candlestick that presents a smoothed view of price action, minimising the market noise shown on traditional Japanese candlestick charts. The colour of the candle, either red or green, further indicates the direction of the trend, with red indicating a downtrend and green indicating an uptrend.

Heikin-Ashi close calculation
Heikin-Ashi charts are a type of price chart that uses averages to show the price movement of an asset. They are constructed like a regular candlestick chart, but the formula for calculating each bar is different. The Heikin-Ashi technique averages price data to create a Japanese candlestick chart that filters out market noise and shows the overall trend more clearly.
The Heikin-Ashi formula is used to calculate each candlestick on the chart. The open, close, high, and low of each candlestick are calculated as follows:
- Open = (open of the previous bar + close of the previous bar) / 2
- Close = (open + high + low + close of the current bar) / 4
- High = the maximum value of high, open, or close of the current period
- Low = the minimum value of low, open, or close of the current period
The open of a Heikin-Ashi candlestick equals the midpoint of the previous candle, and the close of each candlestick equals the average value between the open, high, low, and close. The high and low take the actual high and low of the period, respectively, whichever is the highest or lowest value.
The Heikin-Ashi chart is useful for making candlestick charts more readable and trends easier to analyse. It smooths out price action, making it easier to spot trends and reversals. The charts can also be used to keep a trader in a trade after a trend begins. Traders can use the charts to identify when to stay in trades and when to exit. For example, a long-bodied green Heikin-Ashi candle with no lower wick indicates a strong upward trend, while a long-bodied red candle with no upper wick suggests a strong downward trend.

Heikin-Ashi high calculation
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 constructed like regular candlestick charts, but the formula for calculating each bar is different. The time series is defined by the user, depending on the type of chart desired, such as daily, hourly, or five-minute intervals.
The Heikin-Ashi technique can be used in conjunction with candlestick charts when trading securities to spot market trends and predict future prices. It is useful for making candlestick charts more readable and trends easier to analyse. For example, traders can use Heikin-Ashi charts to know when to stay in trades while a trend persists but get out when the trend pauses or reverses.
The Heikin-Ashi high calculation is the second part of the four components that affect the shape, size, and direction of the candles. The formula for the calculation is as follows:
High = Maximum value of High, Open, or Close (whichever is highest)
High = The highest value of the recent high, open, or close
The Heikin-Ashi high calculation takes the actual high of the period. This could be the highest shadow, the open, or the close. Whichever value is the highest will be the Heikin-Ashi high.
The Heikin-Ashi high is important because it helps to identify the overall trend of the price movement. By taking the maximum value of the high, open, or close, the Heikin-Ashi high provides a clear indication of the highest price point during the period. This information can be used to make informed trading decisions, such as identifying potential resistance levels or determining the strength of an upward trend.

Heikin-Ashi low calculation
Heikin-Ashi charts, developed by Munehisa Homma in the 1700s, are a type of price chart that uses averages to show the price movement of an asset. They are used as a form of technical analysis to identify an asset's price movements with regard to an overall trend. The charts can be applied to any market and are designed to smooth out candlestick patterns and identify trading opportunities.
The LOW of a Heikin-Ashi candlestick takes the actual low of the period. This could be the lowest shadow, the open, or the close, whichever is the lowest. The formula for calculating the low is:
Low = Minimum of Low, Open, or Close (whichever is lowest)
The LOW is calculated as the minimum value from the low, open, or close of the current period. The Heikin-Ashi technique smooths price information over two periods, making it easier to spot trends, price patterns, and reversal points.
The Heikin-Ashi chart is constructed like a regular candlestick chart, but the formula for calculating each bar is different. The time series is defined by the user, depending on the type of chart desired, such as daily, hourly, or five-minute intervals. The down days are represented by filled candles, while the up days are represented by empty candles. These can also be coloured, with up days in white or green, and down days in red or black.
The Heikin-Ashi technique is used to identify a given trend more easily. Hollow white or green candles with no lower shadows signal a strong uptrend, while filled black or red candles with no upper shadow indicate a strong downtrend. Reversal candlesticks have small bodies and long upper and lower shadows.
The Heikin-Ashi technique is a valuable tool in technical analysis, smoothing out price action and making it easier to spot trends and reversals. It reduces market noise and highlights trend direction better than typical candlestick charts. However, it should be noted that Heikin-Ashi charts do not reflect real-time prices and should be used in conjunction with other technical analysis tools.

Heikin-Ashi colour interpretation
Heikin-Ashi candlesticks are calculated using a formula that includes open, high, low, and close values from the current and previous periods. The open of a Heikin-Ashi candlestick is the midpoint of the previous candle, calculated as the average of the open and close prices of the previous bar. The close of a Heikin-Ashi candlestick is the average of the open, high, low, and close prices of the current bar. The high and low values are determined by taking the maximum and minimum values from the current period, respectively.
The colour of a Heikin-Ashi candle is important for interpretation. Typically, up days are represented by hollow or empty candles, which can be coloured white or green, while down days are represented by filled candles, which can be coloured red or black. A long-bodied green Heikin-Ashi candle with no lower wick indicates a strong upward trend, suggesting that traders should hold on to their positions to maximise gains. Conversely, a long-bodied red Heikin-Ashi candle with no upper wick indicates a strong downward trend, signalling a potential exit point for traders.
The emergence of wicks on Heikin-Ashi candles also provides valuable information. If a lower wick appears on a Heikin-Ashi candle during an uptrend, it suggests that the upward momentum may be weakening. Similarly, the appearance of an upper wick during a downtrend indicates that the downward momentum could be losing strength, potentially signalling a shift in trend direction.
Heikin-Ashi charts are designed to filter out the "noise" of day-to-day price fluctuations, providing a smoother representation of price movements. This makes it easier to identify trends and reversals, although it also obscures some price data and gaps. Traders can use Heikin-Ashi charts in conjunction with other technical analysis tools to make more informed decisions about entering or exiting trades.
