Combining Amplitude, Control, and Low K Values in a Chinese Stock Screen

Summary

This Chinese stock-selection proposal screens for shares with amplitude above 1, a “today control” measure above 21, and a K value below 20. The explanation treats the low K reading as a possible entry area because it may be prone to reversal, while the amplitude and control conditions add activity and positioning filters. The post then suggests a broader version that also requires volume above its five-day average, daily turnover below 3%, and dividend yield of at least 1.5%.

The article supplies indicator formulas and Python-style reference code, but no historical test, selected-stock examples, or measured performance. The code’s definitions and units for some fields are not fully explained, and the original amplitude condition is not clearly reconciled with its formula. The author notes that technical-only screens can miss macroeconomic and company fundamentals, restrictive filters can exclude candidates, and adverse news or policy shifts can create risk. The criteria should therefore be treated as a screening idea requiring validation, not as evidence of a reliable buy signal.

Key ideas

• The initial screen combines amplitude above 1, a control measure above 21, and K below 20.
• The post interprets a low K reading as a possible reversal area.
• A proposed expanded screen adds relative volume, a turnover ceiling, and a minimum dividend yield.
• The article provides reference formulas and code but no backtest results.
• Indicator definitions and units need clarification before reproducing the screen.
