Overview

This strategy combines moving averages, volume indicators and price momentum indicators to design a set of quantitative rules to identify the timing of stocks entering the accumulation stage. At this stage, stocks are usually in a price consolidation and storage state, providing a good low-price opportunity.

Strategy Principle

The strategy uses 50-day, 90-day and 200-day simple moving averages to determine price trends. Buy signals are only generated when prices are above the 200-day line. This filters out the uncertainty of major downtrends.

In addition to judging the major trend, the strategy also judges the order of short-term moving averages to confirm the trend. Specifically, it judges if the 50-day line is above the 90-day line.

On the basis that the moving average confirms the major and short-term trends, the strategy combines the PVT volume indicator and the MACD indicator to judge the accumulation characteristics. Buy signals are generated only when the PVT breaks upward, the MACD line is higher than the Signal line, and the volume expands.

Advantages

Compared with using moving averages alone, this strategy also checks the characteristics of volume while confirming the trend. This can more accurately determine the timing of stocks entering the accumulation stage, thus ensuring better entry prices.

By analyzing multiple time frames, this strategy combines medium- and long-term trend judgments and short-term feature judgments to match time frames, which can reduce uncertainty from judging a single time frame incorrectly.

Risks and Solutions

This strategy relies mainly on moving average judgments. When prices fluctuate violently, moving average judgments will fail. At this point, the position size should be reduced or a stop loss exit should be triggered.

In addition, misjudgement on the accumulation stage is possible, thus missing reversal opportunities. This requires observing more feature indicators to confirm judgements.

Optimization Ideas

Machine learning algorithms can be introduced into this strategy by extracting features and model training to achieve automatic judgment of the accumulation stage. This can reduce limitations from manually setting thresholds.

In addition, this strategy can also try the breakpoint functionality to automatically switch parameters under different market environments, making the strategy more robust.

Summary

In summary, this strategy generally adopts the idea of matching prices and volumes to judge the characteristics of stock accumulation stages. While confirming the major direction, it digs short-term accumulation opportunities. There is still room for further improvement in strategy performance by introducing parameter optimization and machine learning.
