Chinese Stock Screen Using Price Amplitude and Weekly MACD

Summary

This Chinese-language post outlines a stock-selection screen combining daily price amplitude, a calendar-year filter for 2021, and weekly MACD above its zero line. It explains the amplitude condition as a way to identify more volatile stocks and treats positive weekly MACD as a sign of an uptrend. Stocks meeting the combined conditions are placed in a candidate pool, rather than given a complete entry and exit plan.

The post includes illustrative formula and Python snippets, but no results from a backtest or live portfolio. Its descriptions also differ slightly on how amplitude is calculated: the formula uses the daily high-low range relative to the low, while the Python example divides that range by the close. The year filter makes the screen specific to 2021, and the post itself notes volatility risk and MACD lag. It suggests combining indicators and setting stop-loss and take-profit levels, without specifying parameters or showing evidence that these changes improve outcomes.

Key ideas

• The screen combines a daily amplitude threshold, the year 2021, and weekly MACD above zero.
• Qualifying stocks are described as candidates for further consideration, not as automatic trades.
• The formula and Python examples use different price denominators for the amplitude calculation.
• The post identifies volatility and MACD lag as risks and suggests additional indicators and trade controls.
• No backtest or live performance results are provided.
