Multi-factor Quantitative Trading Strategy

Author: ChaoZhang, Date: 2023-10-24 11:15:54
Tags:

This is a quantitative trading strategy that combines multiple technical indicators for long/short decisions. It takes into account momentum indicators, trend indicators, Ichimoku cloud and other factors to form the final buy/sell judgements. The strategy has strong stability and risk resistance.

Principle Analysis

The strategy consists of following main components:

Momentum indicators: Parabolic SAR, Leledc, Kaufman Adaptive Moving Average etc.
Trend indicators: RahulMohindar Oscillator, Trend Magic etc.
Ichimoku Cloud: Tenkan-sen, Kijun-sen etc.
Volume indicators: Volume Flow Indicator
Volatility indicators: Wave Trend Oscillator
TD Sequential

These indicators judge the market trend and momentum from different perspectives. Parabolic SAR detects trend reversal points, Leledc measures momentum, Ichimoku Cloud identifies support/resistance levels. Buy/sell signals are generated when most indicators agree on the direction.

The strategy also sets filter conditions to avoid inefficient trades outside specified date ranges per month/day.

Advantage Analysis

Multiple factors improve accuracy and risk resistance
Cross validation with different indicator types avoids failure risk
Filter conditions avoid inefficient trades in unsuitable periods
Pine Script implementation allows easy use on TradingView
Customizable parameters can be optimized for different markets
Visual signals provide intuitive market structure judgements

Risk Analysis

Multi-factor combination requires parameter tuning and weight optimization
Individual indicators may fail in certain market conditions
Improper filter settings may miss opportunities
Over-optimization needs to be avoided
Traders should watch out for indicator failure risks and adjust strategy accordingly

Countermeasures:

Optimize parameters for indicator effectiveness in current market
Adjust weights to amplify effective and reduce ineffective indicators
Fine-tune filters to balance opportunity and risk

Optimization Directions

Add machine learning algorithms to auto-adjust indicator weights
Incorporate more factors like sentiment, money flow etc.
Test optimial parameters across products and timeframes
Evaluate different holding period performances
Combine more filters like seasonality, economic data etc.
Add stop loss strategies

Conclusion

The strategy combines multiple indicators for stronger risk resistance. But indicator failure risks need to be monitored, parameters continuously optimized. Future enhancements may include optimizing indicator weights, adding more factors, testing optimal holding periods etc.
