The prediction of future stock price trend using current and historical stock market data is a research problem for traders and researchers. Recently deep learning methods shown promising performance to extract meaningful information from the given large data. In this paper, we proposed a system to predict the next trading session close price trend from historical stock trading data using long short term memory (LSTM) method. This is a classification problem next trading session close price trend can be uptrend, downtrend, or sideways trend. We built an automated trading system using the results of our classifier. We experimented with the proposed trading system on the American index stocks. Our experimental results show that the proposed method outperforms the buy-and-hold and decision tree-based method.

Stock market prediction is the demonstration of attempting to decide the future estimation of an organization stock or other monetary instrument exchanged on a trade. This paper will exhibit how to perform stock expectations utilizing Machine Learning calculations. Foreseeing securities exchange costs is an intricate assignment that generally includes broad human-PC communication. Because of the connected idea of stock costs, customary bunch preparing techniques can't be used productively for securities exchange examination. In the current framework, the Sliding window calculation is used. This calculation investigates the information, with a window pushing ahead, in the wake of examining the information. It is very tedious for expectation of stocks. While, in the proposed framework, the utilization of LSTM (Long Short Term Memory) calculation, gives compelling outcomes. While analyzing, the superfluous information is overlooked. The current framework is additionally not viable, in taking care of non-straight information. What's more, it is less proficient contrasted with LSTM algorithm. So, to help defeat these, LSTM helps in dealing with the information in a productive way. Indeed, speculators are exceptionally intrigued by the exploration zone of stock value expectations. For decent and fruitful speculation, numerous financial specialists are sharp in knowing the future circumstance of the share trading system. Great and viable expectation frameworks for securities exchange encourage brokers, financial specialists, and investigators by giving steady data like the future course of the share trading system. In this work, an intermittent neural system (RNN) and Long Short-Term Memory (LSTM) are presented, a way to deal with anticipate securities exchange lists. The proposed model is a promising prescient procedure for a very non-direct time arrangement, whose designs are hard to catch by customary models.

Abstract Stocks are an attractive investment option since they can generate large profits compared to other businesses. The movement of stock price patterns on the stock market is very dynamic; thus it requires accurate data modeling to forecast stock prices with a low error rate. Forecasting models using Deep Learning are believed to be able to accurately predict stock price movements using time-series data, especially the Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU) algorithms. However, several previous implementation studies have not been able to obtain convincing accuracy results. This paper proposes the implementation of the forecasting method by classifying the movement of time-series data on company stock prices into three groups using LSTM and GRU. The accuracy of the built model is evaluated using loss functions of Rooted Mean Squared Error (RMSE) and Mean Absolute Percentage Error (MAPE). The results showed that the performance evaluation of both architectures is accurate in which GRU is always superior to LSTM. The highest validation for GRU was 98.73% (RMSE) and 98.54% (MAPE), while the LSTM validation was 98.26% (RMSE) and 97.71% (MAPE).
