Mainland China Stock Screen for Rising Bases and Daily Gains

Summary

This document outlines a mainland China stock-selection screen built around three conditions: amplitude above 1, a rising base, and a gain above 1% on the current day. Its final stated logic also removes ST and *ST shares and describes selling when a candle or closing price falls below the Bollinger midline. The article provides formula and Python examples and mentions MACD, KDJ, market capitalization, and trading volume as possible additions.

The screen combines price movement, a visual trend condition, and daily momentum, but the post does not present a backtest, selected-stock examples, or measured results. It warns that simple conditions may miss attractive stocks and can perform poorly during large market moves or policy changes. The formula and code examples also differ in places, so their exact implementation should be checked before use. The post offers a proposed rule set, not evidence that it is profitable.

Key ideas

• The proposed screen combines amplitude, a rising base, and a daily gain above 1%.
• The final logic excludes ST and *ST shares.
• The described exit condition uses a break below the Bollinger middle band.
• The article suggests adding technical indicators and company or trading data, but reports no performance test.
• Its formulas and Python example are not fully consistent, so implementation details need review.
