A Chinese Stock Screen Combining RSI, Seven Down Sessions, and Auction Change

Summary

This post outlines an A-share screening idea based on an RSI below 65, seven consecutive sessions described as down days, and an opening-auction price change between minus two and five percent. It includes illustrative indicator and data retrieval logic, and mentions additional filters such as exchange, circulating market value, and company information. The stated aim is to identify stocks with recent weakness but without a sharply negative or positive auction move.

The author cautions that technical filters alone can miss macroeconomic, sector, and company risks, and suggests combining them with financial data and other indicators. The examples are not accompanied by a backtest, return figures, or evidence that the conditions identify profitable opportunities. There is also a potential inconsistency: the prose says seven down days, while the sample condition checks whether all seven closes are at or below their opens and then skips when that is true. The precise signal therefore needs verification before use.

Key ideas

• The proposed screen combines RSI below 65, seven sessions with closes no higher than opens, and an auction change between minus two and five percent.
• The sample logic includes additional market value and exchange filters.
• The post recommends considering company, sector, and macroeconomic information alongside technical signals.
• The sample condition appears inconsistent with the stated seven-down-session rule and should be checked.
• No performance test or return evidence is presented.
