The strategy is named “Quantitative Reversal Index Strategy Integrating Dual Trend Signals”. It integrates signals from two different strategies - a short-term reversal signal based on the Stochastic indicator and a long-term trend signal based on volume, combining them into a stable entry signal.
The strategy consists of two parts. The first part uses the 9-day Stoch to generate short-term reversal signals. Specifically, it goes long when the close is higher than the previous close and the Stoch 9-day fast line is below 50 while the slow line is above 50; it goes short when the close is lower than the previous close and the Stoch 9-day fast line is above 50 while the slow line is below 50. This way, the Stoch’s golden cross and death cross form short-term reversal signals.
The second part uses the Negative Volume Index (NVI) to form long-term trend signals. The NVI calculation formula is that if the volume of the day is less than the previous day, the rate of change of the closing price of the day is accumulated; if the volume of the day is greater than or equal to the previous day, the previous day’s value remains unchanged. Long-term trend signals are formed through the moving average of the NVI indicator.
Finally, the strategy combines the two types of signals. Only when the short-term reversal signal and long-term trend signal are in the same direction will an entry signal be formed. This helps filter out false signals and enhance stability.
The biggest advantage of this strategy is the stability of signals. The short-term reversal signal captures short-term market adjustments, while the long-term trend signal ensures the big trend remains unchanged. The combination of the two greatly enhances the stability of the signals and can effectively filter out false signals that have a higher rate from the short-term ones.
In addition, the strategy has few parameters and is easy to optimize. Users only need to adjust the parameters of the NVI to adapt to the characteristics of different markets.
The biggest risk of this strategy is that there may be a time lag between the two types of signals. There may be some lag between the short-term reversal signal and long-term trend signal, which will lead to inconsistent signals for a period of time, unable to form a stable entry signal.
In addition, the NVI indicator is also sensitive to abnormal surges in trading volume, which can lead to wrong judgments of long-term trends.
To mitigate these risks, the parameters of the NVI indicator can be adjusted accordingly, or stop loss can be added to control the loss per trade.
The main aspects for optimizing this strategy include:
Optimize the parameters of the Stoch indicator to improve reversal capturing capability.
Optimize the cycle length of the NVI indicator to enhance long-term trend identification capability.
Add trading volume filters to eliminate false signals from abnormal trading volumes.
Add stop loss strategies to control per trade loss.
The strategy is designed with a stable entry mechanism based on the idea of short-term reversal and long-term trend to effectively control the false positive rate and enhance signal stability. Next steps for optimization include adjusting parameters, adding filter conditions, etc. to further improve the stability of the strategy.
