A Chinese A-Share Screen Combining RSI, Daily Gains, and a Rounded Pattern

Summary

The proposed screen targets main-board Chinese stocks with RSI below 65, a daily gain above 1%, and a rounded price pattern. The article frames the RSI condition as identifying potentially oversold shares and the positive daily move as evidence of momentum. It also treats market-board membership and the rounded formation as additional selection criteria, although it does not define how the pattern is recognized in a reproducible way.

The accompanying indicator logic combines AR and BR measures, their recent changes, moving-average and volatility bands, and a limit on the day's high-low range. A Python example is also provided, but its data fields and calculations are not fully reconciled with the stated screen, so implementation details may need checking. The text offers no backtest results or evidence that the screen earns returns. It warns that fixed conditions can lag changing markets, technical signals can be false, and fundamental measures vary across sectors and market settings; it recommends further filtering, adjustment, and risk controls.

Key ideas

• The stated screen selects main-board shares with RSI below 65, daily gains above 1%, and a rounded chart pattern.
• The article interprets RSI as an oversold signal and the daily gain as positive momentum.
• The indicator reference also uses AR and BR changes, volatility bands, and a daily range filter.
• The rounded-pattern definition and consistency between the stated screen and sample code are unclear.
• No performance evidence is supplied, and the article cautions against relying on fixed technical filters alone.
