Chinese Stock Screen Using Intraday Range, Convertible Bonds, and a Five-Day Average

Summary

This Chinese-language post outlines a stock-selection screen combining a daily high-low range of at least one percent, a nonempty convertible-bond name field, and a closing price above the five-day moving average. It interprets the range condition as selecting more volatile stocks, the bond field as a possible sign of company strength, and the moving-average condition as evidence of an upward technical trend. It also offers example implementations using a market screening formula and Python with market data, alongside suggestions to add indicators such as MACD or KDJ and to consider company and industry fundamentals.

The post warns that restrictive filters may exclude promising stocks and that repeated tests of the five-day average without a breakout can indicate choppy trading. It supplies no backtest, return series, sample definition, or validation of the convertible-bond field as a proxy for financial strength. The screen is therefore a basic hypothesis for further testing, not evidence of an edge; details such as universe selection, data timing, and execution would need careful review.

Key ideas

• The screen selects stocks with a daily high-low range of at least one percent and a close above the five-day moving average.
• It also requires a nonempty convertible-bond name field as a proposed company-strength filter.
• The post suggests adding technical indicators and fundamental information for further screening.
• Strict filters can exclude candidates, while repeated tests of the moving average may reflect sideways movement.
• No backtest or performance evidence is provided to validate the screen.
