Intraday A-Share Screening with RSI and Buying Pressure

Summary

The document presents a short-term Chinese stock screen using RSI below 65, a ratio of external to internal trading volume above a stated threshold, exclusion of special-treatment stocks, and selection before 10 a.m. It also refers to a limit-up pattern and offers sample query and Python approaches. The described idea combines a technical condition with trading-flow measures and a time restriction, aiming to find active stocks early in the session.

The post warns that technical indicators can fail, limit-up behavior can be vulnerable to manipulation and sharp reversals, and data quality affects screening. It also notes that short-term focus can divert attention from long-term company prospects. No backtest results or realized performance are supplied. The examples contain differing details and additional filters, so the post does not define a consistent, reproducible strategy with clear entries, exits, sizing, or transaction-cost treatment.

Key ideas

• The proposed screen uses RSI below 65 and an external-to-internal volume ratio above 1.3.
• It excludes special-treatment stocks and specifies screening before 10 a.m.
• The post invokes a limit-up pattern as an additional selection element.
• The author identifies indicator failure, manipulation, data quality, and short-term risk as concerns.
• No performance study is provided, and the examples do not fully specify a reproducible strategy.
