Overview

This strategy integrates the exponential moving average crossover system and turtle trading system, two popular systematic trading strategies. It is specially designed for the daily timeframe to track market trends in real-time by dynamically managing positions.

Strategy Logic

The strategy contains two sub-strategies: trend strategy and breakout strategy.

The trend strategy uses fast EMA and slow EMA crossovers as trading signals. The fast EMA period is user-defined and the slow EMA period is 5 times of the fast EMA. The signal is generated by dividing the EMA difference by the 252-period return standard deviation, which is volatility-adjusted to produce more reliable signals. It goes long or short when detecting new trend formations.

The breakout strategy uses the average of highest high and lowest low prices over a fixed lookback period as the baseline. Long/short signals are generated when the price breaks out above/below the baseline by a certain percentage.

Position sizing is based on recent price volatility and user-defined annual risk target. Larger size is taken when volatility is low while smaller size is taken when volatility is high. This realizes dynamic position management with risk adjustment.

Hard stops are set as multiples of the average true range. Trailing stops trail recent highest high or lowest low prices.

Advantage Analysis

The main advantages of this strategy include:

1. Combining trend tracking and breakout sub-strategies adapts to different market environments with strong robustness.

2. Applying advanced position sizing and risk management techniques dynamically manages position and effectively controls risk.

3. Volatility-adjusting positions based on recent volatility and annual risk target maintains relatively stable portfolio risk across high/low volatility regimes.

4. Setting stop loss based on actual price fluctuation avoids unnecessary small losses from stop runs.

5. Adjusting trailing stop in real-time flexibly follows trends to book profits and stops out timely.

Risk Analysis

The main risks of this strategy are:

1. Reliance on parameter optimization. Different parameters considerably impact strategy performance so comprehensive testing is needed to find optimum parameters.

2. Frequent stop outs in choppy trends. Stop loss width could be relaxed and stop mechanisms optimized.

3. Sensitivity to initial capital and trading costs. Insufficient initial capital and high trading costs negatively impact profitability.

4. Reliance on accurate volatility estimates for position sizing and risk controls. Inaccurate volatility estimates lead to oversized or undersized positions.

Optimization Directions

The main optimization directions include:

1. Search for optimal parameter sets via more backtesting with larger historical dataset.

2. Improve stop mechanisms by testing various stops like moving stops, time stops, volatility stops etc.

3. Optimize position sizing and risk management by testing different risk targets to find best risk-return profile. Also test impacts of different leverage levels.

4. Try more auxiliary indicators to improve signal accuracy and strategy robustness.

5. Test different holding periods by assisting decisions with higher timeframe signals to improve position allocation accuracy.

Conclusion

This strategy integrates two major categories of trading strategies: trend following and breakouts. By applying advanced dynamic position adjustment techniques, it effectively controls risk while tracking market moves to profit. It demonstrates strong profit potential and is worth further testing and optimization.
