Equity Screening with Price Amplitude, KDJ, and Stock Code

Summary

This document describes an equity screen requiring price amplitude above one, a KDJ value below 20, and a stock code beginning with 60. It presents these conditions as a technical filter for relatively active stocks with a low KDJ reading, then gives formula and Python examples. The code-based condition restricts the eligible universe, while the document suggests broadening selection criteria with industry or market capitalization information.

No backtest results or evidence of returns are included. The text warns that the screen omits company fundamentals and industry characteristics, and that a code-prefix restriction can exclude potential candidates. It also cautions that institutional activity and market sentiment may have short-lived, uncertain effects. The threshold and indicator definitions are not fully standardized across the examples: the amplitude calculation and KDJ expression may depend on platform conventions, and the sample implementation should be checked before use. The proposed addition of fundamental and industry factors is a general suggestion rather than a tested improvement.

Key ideas

• The screen combines amplitude above one, KDJ below 20, and a stock code beginning with 60.
• The document supplies formula and Python examples for applying the conditions.
• A code-prefix rule limits the stock universe and may exclude other candidates.
• The screen omits fundamental and industry information and has no reported performance evidence.
• Indicator definitions and calculations may vary between the examples and platforms.
