SharpCharts users can find Heikin-Ashi under “Chart Attributes” and “Type”. These candlesticks can be black and white or in color. Checking the “color prices” box will show red candlesticks for periods that closed lower and black candlesticks for periods that closed higher. A red filled candlestick means the close was below the open (filled) and the close was lower than the prior close (red). A black hollow candlestick means the close was above the open (hollow) and the close was higher than the prior close (black). The chart below shows both candlestick types side-by-side. Sorry, dual colors are not a charting option. The chart was created by cutting and pasting from one chart to the other.
