The sustainable development of the national economy depends on the continuous
growth and growth of the capital market, and the stock market is an
important factor of the capital market. The growth of the stock market can
generate a huge positive force for the country's economic strength, and the
steady growth of the stock market also plays a pivotal role in the overall
economic pulsation and is very helpful to the country's high economic
development. There are different views on whether the technical analysis of
the stock market is efficient. This study aims to explore the feasibility
and efficiency of using deep network and technical analysis indicators to
estimate short-term price movements of stocks. The subject of this study is
TWSE 0050, which is the most traded ETF in Taiwan's stock exchange, and the
experimental transaction range is 2017/01 ~ 2019 Q3. A four layer Long
Short-Term Memory (LSTM) model was constructed. This research uses
well-known technical indicators such as the KD, RSI, BIAS, Williams% R, and
MACD, combined with the opening price, closing price, daily high and low
prices, etc., to predict the trend of stock prices. The results show that
the combination of technical indicators and the LSTM deep network model can
achieve 83.6% accuracy in the three categories of rise, fall, and flatness.
