The dual reversal trading strategy combines the “123 reversal” and “N consecutive bars down” sub-strategies to efficiently capture trading opportunities when trend reversal occurs. This strategy is more suitable for medium and long term trading.
The “123 reversal” sub-strategy is based on the principle:
Go long when the closing price of the previous two days shows a reverse (i.e. if previous close is higher than the close before previous day, current close is lower than previous close), and the 9-day fast stochastic is lower than 50;
Go short when the closing price of the previous two days shows a reverse (i.e. if previous close is lower than the close before previous day, current close is higher than previous close), and the 9-day fast stochastic is higher than 50.
This sub-strategy identifies trend reversal by judging the reverse of previous two closing prices combined with stochastic indicator.
The “N consecutive bars down” sub-strategy is based on the principle:
Count the recent N bars and see if the closing prices show consecutive downward movement. If yes, a short signal is generated.
This sub-strategy identifies trend reversal by consecutive downward price movement.
The dual reversal trading strategy combines the two sub-strategies by only taking actual positions when both long or short signals are triggered at the same time.
This helps filter out some false signals and makes the trading signals more reliable. The combination of reversal and consecutive down signals can also more accurately identify trend reversal timing.
The dual reversal trading strategy has the following advantages:
Combining multiple sub-strategies helps filter out false signals effectively and improves reliability of signals.
The 123 reversal strategy can accurately identify short term trend reversal points. The N bar consecutive down strategy looks at medium-long term reversal. The two complement each other and capture short term opportunities at medium-long term levels.
Using technical indicators from stock charts makes the strategy flexible to adjust parameters for different products.
The strategy logic is simple and easy to understand and track, suitable for beginners to learn.
Customizable parameters of sub-strategies allow optimization for different products, improving adaptability.
There are also some risks associated with the dual reversal trading strategy:
Reversal signals may give false signals sometimes. Although the combined signals reduce false signals, the risk cannot be completely eliminated. It’s recommended to use stops.
The sub-strategies use simple indicators and may not adapt well to complex market situations. More technical indicators or machine learning could be introduced to improve adaptability.
Sub-strategy parameters need optimization for different products, otherwise overfitting problems may occur.
Reversal strategies fit better for medium-long term. There are risks of being stopped out in the short term. Proper position holding period should be adjusted.
Reversal signals may come during range-bound corrections in a trend. Overall trend should be confirmed to ensure consistency with the major trend.
The dual reversal trading strategy can be optimized in the following aspects:
Introduce more technical indicators, build a multi-factor model to improve adaptability to complex market situations. For example, combining with moving average, Bollinger bands etc.
Add machine learning models to take advantage of multi-dimensional features and improve signal accuracy. For example, introduce random forest or neural networks.
Optimize parameters for different products through training to improve adaptability. Genetic algorithm can be used to search for optimal parameter combinations.
Incorporate stop loss strategies to control single trade risks. Stop loss levels can also be data-driven optimized.
Develop dynamic position sizing mechanisms based on market conditions and sub-strategy signals to lower risks.
Introduce trend filtering modules to avoid signal contradictions with the overall trend. Simple moving averages can be used to determine trends.
The dual reversal trading strategy efficiently captures trend reversals by combining the 123 reversal and N consecutive bars down sub-strategies. It fits better for medium-long term holdings and can filter out false signals to provide reliable trading opportunities during trend reversals. But there are also some limitations that need addressing through introducing more technical indicators and optimization, together with stop loss and position sizing to lower risks, in order to adapt to more complex market environments. Overall, it provides a simple and straightforward approach for trend reversal trading and serves as good learning materials for beginners to understand and learn about quantitative trading strategies. With more optimization techniques, it can become a very practical quantitative trading strategy.
