Rising-Base Stock Screen with Range and Trend Filters

Summary

This Chinese equity screening concept combines three conditions: amplitude above 1, a rising price base, and the start of a major upward move. The post illustrates these with a formula using amplitude, successive bottom comparisons, and an ordering of slow, middle, and fast lines. Its Python example also applies rolling price logic and sorts selected stocks by percentage change.

The article does not define the terms “rising base” or “major upward move” in a way that makes them fully reproducible, and supplies no backtest or performance evidence. It notes that temporary market swings, data precision, and subjective interpretation may affect results. It proposes adding market-trend, activity, or fundamental inputs, and mentions machine learning as a possible way to tune indicators. These are suggestions rather than validated improvements; the sample rolling-window logic also depends on an externally defined window size.

Key ideas

• The screen requires amplitude above 1, a rising base, and a signal interpreted as the start of a major advance.
• The example formula represents these conditions with successive bottom comparisons and ordered trend lines.
• The post acknowledges that subjective definitions and data quality can affect signal reliability.
• No backtest evidence is provided, and proposed added indicators or machine learning remain untested suggestions.
