Chinese Stock Screening for Higher Lows and Longer Trading Histories

Summary

This Chinese stock screen combines a daily price-range condition, a minimum listing history of more than one year, and a higher-low pattern. The document describes higher lows as successive troughs rising during a decline, which may indicate strengthening buying interest. It provides a technical formula and a Python example that compares recent lows to identify candidates. No performance results, benchmark, or validation are reported, so the screen is a rule proposal rather than demonstrated evidence of predictive value.

The author warns that a rebound after a higher low may fail to continue and that a local low can be difficult to distinguish from a genuine trend reversal. The code illustrates one way to inspect recent price data, but the document does not fully specify how to define the amplitude filter in the implementation. It suggests adding indicators such as KDJ to assess rebound signals. Any use would require clear definitions, testing across market conditions, and attention to false reversal signals.

Key ideas

• The screen combines a price-range condition, more than one year of listing history, and rising swing lows.
• Higher lows are presented as a possible sign of increasing buying interest during a decline.
• A rebound may fail, and a local rise in troughs does not establish a lasting reversal.
• The document offers no backtest or other evidence of predictive performance.
• Additional indicators are suggested to help assess whether a rebound is credible.
