A Chinese A-Share Screen Combining Consecutive Limit-Ups and Institutional Flow

Summary

This Chinese-language post proposes screening equities by price range, recent consecutive limit-up sessions, and a positive institutional-flow measure. It interprets a large daily range as a sign of activity, a three-session limit-up sequence as evidence of demand, and positive institutional flow as a favorable signal. The post then recommends adding company fundamentals, sector conditions, and trend measures to reduce reliance on short-term market flows.

The document acknowledges that the screen can select overvalued companies and that technical signals and crowd-driven flows may be unstable or exposed to macroeconomic and sector risks. It offers formula and Python examples, but the displayed conditions and code do not fully establish a reliable implementation of the stated three-consecutive-limit-up rule. No backtest, benchmark, transaction-cost analysis, or measured returns are provided, so the claimed usefulness is not supported by performance evidence. The proposed screen is best understood as a rough idea requiring data validation and explicit risk controls.

Key ideas

• The initial screen combines a daily range threshold, three consecutive prior limit-up sessions, and positive institutional flow.
• The post interprets the conditions as signs of activity, recent demand, and institutional interest.
• It suggests adding fundamentals, industry trends, and additional technical indicators to refine selection.
• The post warns that flow and price signals can be unstable and may select overvalued companies.
• No performance testing is reported, and the example implementation may not precisely match the described rule.
