500 Index. Mutual Relationship between nifty Stock Index Future and Spot Markets. Thanks for your help! Specifically, we choose US dollar index as the proxy for exchange rate. The main contribution of this work is that it is the first attempt to apply stacked autoencoders to generate the deep features of the ohlc, technical indicators and macroeconomic conditions as a multivariate signal in order to feed to a lstm to forecast future stock. The back-propagation algorithm is used to train the wsaes-lstm model as well as the models in the experimental control group including wlstm, lstm and RNN. Also, the impact of the stationarity of time series on the prediction power of ANNs is quite small. Generally speaking, there are three main deep learning approaches widely used in studies: convolutional neural networks 12, deep belief networks 13 and stacked autoencoders.
For example, both Hang Seng and S P 500 index have two types of future products: the standard future contract and the mini future contract. We first demonstrate the accuracy measurements selected to judge the predictive performance. The first set is historical stock trading data, such as the Open, High, Low and Close price (ohlc) 26 28, and the second is the technical indicators of stock trading. Then, we evaluate the models performance from two dimensions: predictive accuracy and profitability. For continuous wavelet transform (CWT the wavelet function can be defined by: (1) where a and are the scale factor and translation factor, respectively. The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.
( t ) is the basis wavelet, which obeys a rule named the wavelet admissibility condition 53 : about.com work from home jobs (2) where ( ) is a function of frequency and also the Fourier transform of ( t ). To confirm the robustness of our findings, we examine the statistical significance of the differences between wsaes-lstm and the other three models. Palangi H, Ward R, Deng. The computation procedure of transaction costs in the spot stock market follows the rule that we describe above. Nourani V, Komasi M, Mano. The results show a rather significant inclination of the designed neural network to predict both the sign and the size of future currency rate change. Krizhevsky A, Sutskever I, Hinton GE, editors.
