Mainboard Stock Screening with RSI, Daily Gains, and DEA Direction

Summary

This Chinese-language post describes a technical screen for mainland China mainboard stocks. It selects shares with RSI below 65, a daily gain above 1%, and a rising DEA measure. The examples also include a close-at-recent-high condition and exchange or market filters. The post provides sample screening logic in a database-style query and Python, though the implementations do not align perfectly with the written rules: the code adds conditions and appears to use DEA-related values differently from the prose. Treat those details as implementation examples requiring review.

The author suggests adding financial quality or growth measures and considering market trends to balance the technical filters. No backtest results or performance evidence are presented. The post warns that indicator signals can be misleading and that focusing on technical measures may overlook company fundamentals. It recommends studying each candidate and applying risk controls, but it does not define position sizing, exits, or a complete portfolio process.

Key ideas

• The screen combines RSI below 65, a daily gain above 1%, mainboard eligibility, and a rising DEA measure.
• The code examples add recent-high and exchange-related filters that are not stated consistently in the prose.
• The author proposes adding financial measures such as earnings growth or dividends to broaden the selection process.
• The post provides no performance test, and its indicator signals may be false or incomplete.
• Risk controls and review of company fundamentals are recommended, but specific rules are not supplied.
