Abstract
The aim of this study is to examine the predictive power of three-day candlestick patterns, improve performance by adopting a variable holding period approach, and identify two behavioral factors to explain the sources of profitability when using candlesticks. Using the Taiwan component stocks daily data for the period from 4 January 1992 to 31 December 2012, this study provides strong support for candlestick trading strategies, even when transaction costs are carefully taken into account. In addition, this study shows that candlestick charting can yield more substantial returns by using the variable holding period approach. Finally, trading volume per trade and turnover rates seem able to explain the profitability of using candlesticks.
