Overview

The Moment Reversal Strategy Based on Multi-factor Model combines multi-factor model and momentum reversal strategy to achieve more stable and higher returns. The strategy uses the 123 reversal and confluence indicators as two independent signals and establishes a position when the two signals are consistent.

Strategy Principle

The strategy consists of two sub-strategies: 123 reversal strategy and confluence indicator strategy.

The 123 reversal strategy generates trading signals based on whether the price has risen or fallen continuously for 2 days, combined with the STOCH indicator to judge whether the market is overcooled or overheated. Specifically, when the price rises continuously for 2 days and the 9-day STOCH slow line is below 50, it is bullish. When the price falls continuously for 2 days and the 9-day STOCH fast line is above 50, it is bearish.

The confluence indicator strategy utilizes the superposition of moving averages and oscillators of different cycles to determine the trend direction and strength. Including linear weighting, sine addition and other methods to comprehensively judge the long and short momentum. The indicator is graded and returns 1 to 9 indicating strong bullish momentum and -1 to -9 indicating strong bearish momentum.

Finally, the strategy establishes long or short positions when both signals are consistent.

Advantage Analysis

The Moment Reversal Strategy Based on Multi-factor Model combines reversal factors and momentum factors to capture reversal opportunities while following the trend to avoid false breakouts, thus having higher win rates. The advantages of the strategy are specifically reflected in:

As a reversal signal source, the 123 reversal strategy can capture excess returns from short-term reversals.
The confluence indicator judges the trend direction and strength to avoid the risk of loss caused by too large reversal space.
The combination of the two strategies complements each other’s strengths and weaknesses to some extent and improves signal quality.
Compared with a single model, the combination of multiple factors can improve the stability of strategies.

Risk Analysis

Although the Moment Reversal Strategy Based on Multi-factor Model has certain advantages, there are still some risks:

The risk of loss caused by reversal not being completed and prices turning around again. Appropriate stop loss can be set to guard against this.
Unable to determine direction when two signals are inconsistent. Parameter adjustment can be made to increase the matching degree.
The model is too complex with too many parameters, which is difficult to adjust and optimize.
Multiple submodels need to be monitored simultaneously, resulting in greater difficulty in operation and psychological pressure. Automatic trading elements can be introduced to reduce operational burden.

Optimization Directions

The Moment Reversal Strategy Based on Multi-factor Model can be optimized in the following aspects:

Adjust the parameters of the 123 reversal strategy to make reversal signals more accurate and reliable.
Adjust the parameters of the confluence indicator to make the determined trends closer to the actual ones.
Introduce machine learning algorithms to automatically optimize parameter combinations.
Add position management module to make position adjustment more quantitative and systematic.
Add stop loss module. Effectively control single loss by presetting stop loss price.

Summary

The Moment Reversal Strategy Based on Multi-factor Model comprehensively employs reversal factors and momentum factors. On the basis of ensuring relatively high signal quality, it obtains higher win rate through multi-factor stacking. The strategy has the dual advantages of capturing reversal opportunities and following the trend. It is an efficient and stable quantitative strategy. Follow-up optimizations can be made in aspects such as parameter adjustment and risk control to further improve the strategy’s risk-reward ratio.

// ================================================================
// Here is Gary`s commentary:
// Since the Confluence indicator returned several "states" (bull, bear, grey, and zero), 
// he modified the return value a bit:
// -9 to -1 = Bearish
// -0.9 to 0.9 = "grey" (and zero)
// 1 to 9 = Bullish
// The "grey" range corresponds to the "grey" values plotted by Dale's indicator, but 
// they're divided by 10.
