The Long Short-Term Memory (LSTM) Model Combines with Technical Analysis to Forecast Cryptocurrency Prices

Cryptocurrency has a considerable market value and massive trading volume. Moreover, it is also known for its extreme volatility. Thus, this paper intends to attempt a new approach to forecast cryptocurrency prices by combining the long short-term memory (LSTM) model and technical analysis. The LSTM model has the advantages of a recurrent neural network and solves the gradient disappearance problem that adjusts weights and biases of long- or short-term memory, which is suitable for processing time series problems. Meanwhile, technical analysis is still a critical price trend analytical method. Overall, the results show that the combined methods get a better effect than only using a single price as a feature. Under the same condition, only using price as features for LSTM model accuracy rate is more than 40% for two different error tolerance, but the model accuracy rate will be improved by more than 60% and 90% if traditional technical indicators are combined as features at the best condition. Moreover, the error rate also reduces for the combined approach compared to the single approach.
