Heikin-Ashi, also sometimes spelled Heiken-Ashi, means "average bar" in Japanese. The Heikin-Ashi technique can be used in conjunction with candlestick charts when trading securities to spot market trends and predict future prices. It's useful for making candlestick charts more readable and trends easier to analyze. 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. Most profits are generated when markets are trending, so predicting trends correctly is necessary.
KEY TAKEAWAYS
The Heikin-Ashi technique is used with candlestick charts to help traders identify and analyze trends.
There are five primary signals used in Heikin-Ashi charts.
Heikin-Ashi charts can be used in any market.
The Heikin-Ashi Formula
Normal candlestick charts are composed of a series of open-high-low-close (OHLC) candles set apart by a time series. The Heikin-Ashi technique shares some characteristics with standard candlestick charts but uses a modified formula of close-open-high-low (COHL):
Close
=
1
4
(Open
+
High
+
Low
+
Close)
(
The average price of the current bar
)
Open
=
1
2
(Open of Prev. Bar
+
Close of Prev. Bar
)
(
The midpoint of the previous bar
)
High
=
Max[High, Open, Close
]
Low
=
Min[Low, Open, Close]
Close=
4
1
(Open+High+Low+Close)
(The average price of the current bar)
Open=
2
1
(Open of Prev. Bar+Close of Prev. Bar)
(The midpoint of the previous bar)
High=Max[High, Open, Close]
Low=Min[Low, Open, Close]
Constructing the Chart
The Heikin-Ashi chart is constructed like a regular candlestick chart, except the formula for calculating each bar is different, as shown above. 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 colored in by the chart platform, so up days are white or green, and down days are red or black, for example.
