The dataset was obtained from Brazilian stock exchange market , and the primary techniques they exploited were a combination of multi-objective optimization, genetic programming, and technical trading rules. For optimization, they leveraged genetic programming to optimize decision rules. They included a historical period, which was a critical moment of Brazilian politics and economics when performing validation. This approach reinforced the generalization strength of their proposed model. When selecting the sub-dataset for evaluation, they also set criteria to ensure more asset liquidity. While the baseline of the comparison was too basic and fundamental, and the authors did not perform any comparison with other existing models. Lee in used the support vector machine along with a hybrid feature selection method to carry out prediction of stock trends.
In February 2012, the Investment Industry Regulatory Organization of Canada introduced single-stock circuit breakers. Investment is usually made with an investment strategy in mind. Besides comparing the performance across popular machine learning models, we also evaluated how the PCA algorithm optimizes the training procedure of the proposed LSTM model. We recorded the confusion matrices comparison between training the model by 29 features and by five principal components in Fig.11. The model training using the full 29 features takes 28.5 s per epoch on average. While it only takes 18 s on average per epoch training on the feature set of five principal components. PCA has significantly improved the training efficiency of the LSTM model by 36.8%.

It would be difficult for this model to predict trading activities in shorter time intervals since the data volume would be increased drastically. We have built the dataset by ourselves from the data source as an open-sourced data API called Tushare . The novelty of our proposed solution is that we proposed a feature engineering along with a fine-tuned system instead of just an LSTM model only.

Stock market is one of the major fields that investors are dedicated to, thus stock market price trend prediction is always a hot topic for researchers from both financial and technical domains. In this research, our objective is to build a state-of-art prediction model for price trend prediction, which focuses on short-term price trend prediction. The secondary purpose the stock market serves is to give investors – those who purchase stocks – the opportunity to share in the profits of publicly-traded companies. The other way investors can profit from buying stocks is by selling their stock for a profit if the stock price increases from their purchase price. For example, if an investor buys shares of a company’s stock at $10 a share and the price of the stock subsequently rises to $15 a share, the investor can then realize a 50% profit on their investment by selling their shares. We leveraged another test on adding pre-procedures before extracting 20 principal components from the original dataset and make the comparison in the aspects of time elapse of training stage and prediction precision.

In this method, one holds a portfolio of the entire stock market or some segment of the stock market (such as the S&P 500 Index or Wilshire 5000). The principal aim of this strategy is to maximize diversification, minimize taxes from realizing gains, and ride the general trend of the stock market to rise. Sometimes, the market seems to react irrationally to economic or financial news, even if that news is likely to have no real effect on the fundamental value of securities itself. However, this market behaviour may be more apparent https://dotbig.com/ than real, since often such news was anticipated, and a counter reaction may occur if the news is better than expected. Therefore, the stock market may be swayed in either direction by press releases, rumors, euphoria and mass panic. People trading stock will prefer to trade on the most popular exchange since this gives the largest number of potential counter parties and probably the best price. However, there have always been alternatives such as brokers trying to bring parties together to trade outside the exchange.
