Stock Screening with Price Amplitude and Rising KDJ K

Summary

This stock-selection rule looks for shares with amplitude above 1, more than one year since listing, and a rising KDJ K value. The article interprets amplitude as a sign of active price movement, the listing-age filter as a way to avoid very new shares, and a positive K change as evidence of improving recent momentum. It includes a KDJ calculation outline and a Python example that attempts to screen listed Chinese shares.

No backtest, benchmark, or measured outcome is presented, so the stated potential is not supported by performance evidence in the document. The author cautions that the screen relies on price behavior and KDJ alone, leaving out company fundamentals and broader market conditions. The article suggests combining additional indicators and setting stop losses and position controls, but it does not specify how to choose those settings. The code example's data source and fields may not consistently match the described KDJ calculation, so implementation details need independent validation.

Key ideas

• The screen combines amplitude above 1, listing age greater than one year, and a positive change in KDJ K.
• The article treats the KDJ condition as a short-term momentum filter.
• It provides a formula outline and a Python example, but reports no measured strategy results.
• The rule omits fundamental and market context, and the example implementation needs validation.
• The author suggests adding indicators and applying stop-loss and position controls.
