A Chinese Stock Screen Using Volume, Opening Gains, and Limit-Ups

Summary

This Chinese-language post outlines a daily stock selection screen based on three filters: rank stocks by trading volume or a stated measure of capital strength, keep those whose gain at 9:25 is below 6%, and require at least two limit-up sessions in the previous 500 trading days. The author interprets the filters as combining market attention, a restrained pre-open rise, and a history of strong price moves. The post also suggests adding market capitalization, valuation, and technical indicators as further filters.

The document gives no backtest results, execution rules, holding period, or evidence that the proposed filters predict returns. Its sample code is incomplete, and the volume-ranking description is not fully consistent with the code fragment, which refers to a 30-day average. It warns that the approach may overemphasize short-term performance and miss longer-term fundamentals, and that it may fail to identify market leaders. Treat the screen as an informal strategy sketch rather than a validated trading system.

Key ideas

• The screen combines a volume-based ranking with a pre-open gain ceiling and a historical limit-up count.
• It requires at least two limit-up sessions during the prior 500 trading days.
• The post proposes market capitalization, valuation, and technical indicators as optional additional filters.
• The author warns that the screen may favor short-term strength and still fail to identify market attention correctly.
• No performance analysis is provided, and the code fragment is incomplete.
