A Stock Screen Combining Low RSI, Seven Down Days, and a Limit-Down Auction

Summary

This post outlines a Chinese equity screen requiring RSI below 65, seven consecutive down sessions, and a prior-day 9:15 auction match price at the limit-down level. Its final stated rule also includes a market-cap band of 5–10 billion yuan. The post explains these conditions as a combination of a technical indicator, a sustained decline, and an unusually weak auction signal, and gives formula references and sample Python logic for screening stocks.

No backtest, performance measurements, or validation of the proposed interpretation is provided. The post notes that the auction price may not reflect a stock’s underlying value and that omitting fundamentals can lead to inaccurate selections. Its code contains data-source and condition details that may not precisely implement the written rule, so the signal definitions and market data should be verified before practical use. The screen describes a candidate selection process; it does not establish that a rebound or any other outcome will follow.

Key ideas

• The screen combines RSI below 65, seven consecutive down sessions, and a prior-day auction price at limit down.

• The post interprets the auction condition as a possible sign of weak sentiment or pressure.
• It presents formulas and sample screening code but no test results or predictive evidence.
• The post cautions that auction prices may not represent underlying value and fundamentals are omitted.
