Classic chart patterns and trend lines can also be used on Heikin-Ashi charts. In contrast to normal candlesticks, Heikin-Ashi Candlesticks are more likely to trend with strings of consecutive filled (black) candlesticks and strings of consecutive hollow (white) candlesticks. The chart below shows Apache (APA) falling with a string of filled candlesticks in late October. The Heikin-Ashi candlesticks formed a falling wedge and APA broke resistance with a surge in early November. A triangle consolidation then took shape as the stock consolidated in November. The upside breakout signaled a continuation of the bigger uptrend.
