Chinese A-Share Screening with RSI, Daily Gains, and Auction Buy Flows

Summary

This stock-screening idea combines a relative strength index below a stated ceiling, a positive daily price move, and a main-board listing requirement with buying activity from large and extra-large orders during the auction. The stated rationale is to combine technical conditions with market sentiment and evidence of large-order interest. The document also gives example indicator formulas and a Python-oriented outline for gathering market and historical data, calculating filters, and combining order-flow measures.

The strategy is presented as a selection rule, not a complete trading system: it does not define portfolio construction, exit rules, position sizing, or a validated return record. The text itself flags mistimed large-order signals, news interference, and unstable market sentiment as risks, and suggests that adding other indicators or changing the daily-gain threshold could alter the screen. Its sample implementation contains inconsistencies with the stated criteria, so the exact data fields and thresholds would need careful verification before use.

Key ideas

• The screen combines an RSI ceiling, a minimum daily gain, and a main-board universe filter.
• Auction-period large and extra-large buy flows are used as a proxy for institutional interest.
• The document provides example formulas and a data-processing outline for implementing the screen.
• It identifies news, signal timing, and unstable sentiment as sources of false selection signals.
• The article does not establish profitability or specify portfolio and exit management.
