A Chinese Stock Screen Combining Price Range, Amplitude, and KDJ

Summary

This Chinese-language post describes an equity screening rule based on daily amplitude above 1%, a closing price of 18.5 yuan, and a KDJ K value below 20. It interprets the KDJ threshold as an oversold condition and suggests ranking qualifying stocks by trading value. The post includes formula and Python examples and explains that the KDJ calculation uses parameters 9, 3, and 3.

The author cautions that a low K value alone does not establish a buying opportunity and may misread short-term market moves. The examples do not report a backtest, returns, or evidence that the exact-price condition improves selection. The post recommends combining technical and fundamental measures and using profit-taking and stop-loss rules, but these additions are suggestions rather than tested components of the screen.

Key ideas

• The screen requires amplitude above 1%, a closing price of 18.5 yuan, and KDJ K below 20.
• The KDJ threshold is treated as a possible oversold signal.
• The post suggests sorting selected stocks by trading value.
• It warns that the signal may misread short-term fluctuations and needs confirmation.
• No performance test is presented for the screening rule.
