A Chinese Stock Screen Using Opening Gain, Range, and the Five-Day Average

Summary

This document describes a short-term Chinese equity screen combining daily amplitude above 1, a 9:25 price gain below 6%, and a stock price or average price above its five-day moving average. The intended rationale is to find stocks with some price movement and a stronger near-term trend while excluding unusually large opening gains. It also suggests adding company fundamentals and industry trends for a fuller assessment.

The post includes indicator and Python examples, but they do not fully implement the stated screen consistently: the formulas refer to closing prices and moving-average direction, while the prose specifies a 9:25 move and average price. The Python example also has data and condition mismatches, so it should not be treated as a verified implementation. No backtest or performance evidence is provided. The approach is a simple technical filter, vulnerable to noisy price moves, trading interruptions, and broader market or company factors it does not model.

Key ideas

• The proposed screen combines amplitude above 1, a 9:25 gain below 6%, and a price relation to the five-day moving average.
• The moving-average condition is intended to favor stocks with stronger short-term trends.
• The author recommends considering company fundamentals and industry trends alongside the technical filters.
• The examples do not consistently match the prose conditions, and the document supplies no performance test.
