Heikin-Ashi Chart

The Heikin-Ashi is a type of candlestick chart that shares many characteristics with standard candlestick charts, but differs because of the values used to create each bar. Instead of using the open-high-low-close (OHLC) bars like standard candlestick charts, the Heikin-Ashi technique uses a modified formula.

Calculation

Normal candlestick charts are composed of a series of open-high-low-close (OHLC) bars set apart by a time series. The Heikin-Ashi technique uses a modified formula:

Price	Formula
xClose	(Open + High + Low + Close) / 4
xOpen	[xOpen(Previous Bar) + Close(Previous Bar)] / 2
xHigh	Max(High, xOpen, xClose)
xLow	Min(Low, xOpen, xClose)
