Overview

This strategy combines multiple technical indicators to implement momentum reversal and dual-rail matching to generate trading signals. The strategy uses 123 pattern to determine reversal points and matches signals with the ergodic CSI indicator to track trends. It aims to capture medium-short term trends and achieve high profits.

Principles

The strategy contains two parts:

1. 123 pattern to determine reversal points
2. Ergodic CSI indicator to generate matching signals

The 123 pattern judges price reversal based on the close prices of the recent 3 bars. Specifically:
If the close price of the 3rd bar rises compared to the previous 2 bars, and both fast and slow stoch are below 50, it is a buy signal.
If the close price of the 3rd bar falls compared to the previous 2 bars, and both fast and slow stoch are above 50, it is a sell signal.

The ergodic CSI indicator considers multiple factors like price, true range, trend indicators to comprehensively determine market conditions and generate buy/sell zones.
When indicator rises above buy zone, it generates a buy signal. When indicator falls below sell zone, it generates a sell signal.

Finally, the reversal signals from 123 pattern and zone signals from ergodic CSI are "ANDed" to produce the final strategy signal.

Advantages

1. Captures medium-short term trends, high profit potential
2. Reversal pattern determination effectively catches turning points
3. Dual-rail matching reduces false signals

Risks

1. Individual stocks may diverge, leading to stop loss
2. Reversal patterns susceptible to impact from range-bound markets
3. Limited parameter optimization space, performance fluctuation high

Optimization Directions

1. Optimize parameters to improve strategy profitability
2. Add stop loss logic to reduce single trade loss
3. Incorporate multi-factor models to improve stock selection

Conclusion

This strategy effectively tracks medium-short term trends by combining reversal patterns and dual-rail matching. Compared to single technical indicators, it has higher stability and profit levels. Next steps are to further optimize parameters, add stop loss and stock selection modules to reduce drawdowns and improve overall performance.
