A Chinese Stock Screen Using Amplitude, Listing Age, and MACD

Summary

This stock-selection proposal screens for shares with daily amplitude above one percent, a listing history longer than one year, and a MACD value below zero two trading days earlier. The post presents the negative MACD condition as a way to identify recent weakness that might offer an entry point, while the age filter excludes newer listings. It includes a formula reference and a Python example using market data, but does not give a full trading plan, ranking method, or rules for entering and exiting positions.

The explanation notes that MACD can lag turning points, so a negative reading from two days earlier does not reliably identify a timely entry or indicate when to adjust or sell. It suggests combining the signal with other technical measures, volume and price analysis, and broader market context. The examples also appear inconsistent with the stated requirements: the Python sample does not clearly apply the amplitude filter, and its formula’s sign conditions warrant verification. No historical performance or validation is supplied; the screen is a candidate rule set rather than demonstrated evidence of an effective strategy.

Key ideas

• The proposed screen combines daily amplitude above one percent, more than one year since listing, and a negative MACD reading from two sessions earlier.
• The author frames the MACD condition as a possible way to locate weakness before an entry.
• MACD may lag turning points, so the signal can be late or misleading.
• The examples should be checked because they do not clearly match every stated filter.
• The post reports no backtest or evidence that the screen is profitable.
