A-Share Screen Using RSI, Moving-Average Trend, and Limit-Up Exclusion

Summary

This A-share stock screen selects shares with a 14-period RSI below 65, a 20-day moving average above the 120-day average, and no limit-up move on the prior day. The final version adds a rising 20-day average as a trend condition. The accompanying examples rank candidates by stock popularity, using a popularity list as the starting universe.

The post cautions that technical indicators alone do not describe company fundamentals and may admit financially weak or risky firms. It suggests adding measures such as revenue growth, profit, and shareholder control, and adapting technical conditions to market behavior. No backtest results or evidence of profitability are provided, and the code examples do not demonstrate that the screen was validated out of sample. The rules are therefore a screening recipe, not evidence of a complete or robust trading strategy.

Key ideas

• The screen requires RSI below 65 and a 20-day average above the 120-day average.
• It excludes stocks that hit the stated limit-up threshold on the previous day.
• The final rule also requires the 20-day average to be rising.
• Popularity is used to order candidates, but the post provides no performance validation.
• The author notes that technical-only screening omits important information about company fundamentals.
