Strategy Logic
This strategy combines a neural network model, RSI indicator and Super Trend indicator for trading.
The logic is:
Build a neural network model with inputs including volume change, Bollinger Bands, RSI etc.
The network predicts future price change rate
Calculate RSI values and combine with predicted price change
Generate dynamic stop loss lines based on RSI
Go short when price breaks above up stop loss; go long when price breaks below down stop
Use Super Trend trend judgment for filtration
The strategy leverages neural networks’ ability to model complex data, with additional signal verification from indicators like RSI and Super Trend to improve accuracy while controlling risk.
Advantages
Neural networks model multidimensional data to determine trends
RSI stops protect profits, Super Trend assists judgement
Multiple indicators combine to improve signal quality
Risks
Requires large datasets for neural network training
Fine-tuning of RSI and Super Trend parameters needed
Performance depends on model predictions, uncertainties exist
Summary
This strategy combines machine learning with traditional techniques for efficiency with risk controls. But parameters and model interpretability need improvement.
