Stock Rebound Screen Using Seven Down Closes and Afternoon Inflows

Summary

This Chinese-language post outlines an equity screen requiring price amplitude above one, a measure described as afternoon large-order net inflow, and seven consecutive sessions with closes below the preceding close. It then says to choose the strongest recent gainers from the qualifying names. The proposed rationale combines active trading and buying-flow signals with a deeply declining price sequence, seeking a short-term rebound while favoring stocks with recent relative strength. The post includes indicator formulas and a Python example, but that example’s calculations and ranking do not clearly implement every part of the written description.

No backtest, trade results, or supporting data are supplied. The post acknowledges that the screen may continue selecting stocks during persistent declines and may neglect company fundamentals. It suggests reconsidering the consecutive-decline measure and testing and refining the rules. The signal definitions, data implementation, ranking period, and execution assumptions would need clarification before the screen could be evaluated or reproduced reliably.

Key ideas

• The screen combines amplitude, an afternoon large-order inflow measure, and seven consecutive declining closes.
• The stated selection step favors qualifying stocks with the strongest recent gains.
• The post frames the setup as a possible short-term rebound opportunity but supplies no performance evidence.
• Persistent declines, weak fundamentals, and inconsistencies between the written rule and code are important limitations.
