Tags: ## Overview

The dual golden cross reversal trading strategy is a trading strategy that combines multiple technical analysis indicators. It incorporates the 123 reversal pattern strategy and the prime number bands indicator to integrate diverse trading signals and obtain more reliable trading signals.

## Strategy Principles

The strategy consists of two sub-strategies:

1. 123 reversal pattern strategy

It generates trading signals based on the closing prices of stocks. Signals are triggered when the relationship between closing prices of consecutive days change. Specifically, a short signal is generated when the previous closing price is higher than that of two days ago, and the current closing price is lower than previous day. A long signal is generated when the previous closing price is lower than that of two days ago, and the current closing price is higher than previous day. Additionally, the signals are only activated when stochastic oscillator crosses over. That is, the long signal is activated only when the fast line is below the slow line. The short signal is activated only when the fast line is above the slow line.

2. Prime number bands strategy

This strategy uses the unique distribution of prime numbers to determine price fluctuation ranges. It first locates the highest and lowest prime numbers within a certain percentage range of the price, and plots the two prime number series as bands. Trading signals are generated when the price touches the bands. Specifically, a long signal is triggered when the price breaks above the upper band. A short signal is triggered when the price breaks below the lower band.

The two sub-strategies are combined to generate the final trading signals. That is, the long signal is generated only when both strategies produce long signals. Similarly for the short signals. No trading is executed if the signals from the two strategies contradict with each other.

The strategy has the following advantages:

1. Increased profitability through signal integration

By combining signals from two different types of strategies, the reliability of the signals can be verified to identify high-probability profitable trading opportunities.

2. High win rate of 123 reversal pattern

The 123 reversal pattern is a classic contrarian strategy that can capture reversal opportunities arising from short-term overbought and oversold situations, thus possessing relatively high win rate in live trading.

3. Prime number bands capture price patterns

Prime number bands make use of the unique randomness of prime numbers to determine price fluctuation ranges, avoiding subjective bias and enhancing the objectivity of trading signals.

4. Novel strategy logic avoids exploitation

The innovative integration of multiple indicators makes the strategy less susceptible to reverse engineering and exploitation by copycat strategies.

## Risk Analysis

The strategy also carries the following risks:

1. Failed reversal risk

As a reversal strategy, failed reversals of the 123 pattern can lead to losses.

2. Failure of prime number bands

The prime number bands depend on proper parameter tuning. Incorrect parameters may render it ineffective.

3. Increased trade frequency from multiple signals

More trades can be generated as two signal sources are combined. Excessive trading costs may erode profits if not properly controlled.

4. Difficult optimization

Optimizing parameters from two integrated strategies can be challenging.

## Optimization Suggestions

The strategy can be optimized in the following aspects:

1. Incorporate stop loss to limit per trade loss.

2. Optimize prime number bands parameters to fit the latest market conditions.

4. Introduce machine learning algorithms to automate strategy parameter optimization.

5. Add more confirmation indicators like volume indicators to further improve signal accuracy.

## Summary

The dual golden cross reversal trading strategy integrates multiple technical indicators to filter out noise trades and identify high-probability trading opportunities through signal verification. But it also carries inherent risks that need to be mitigated through proper optimization to strengthen the strategy. With risks under control, the strategy can become a relatively stable and reliable quantitative trading strategy.
