Chinese Stock Screen Combining Price Range, Morning-Star Pattern, and KDJ Growth

Summary

The post outlines a Chinese stock-selection screen combining price amplitude above a threshold, a three-candle morning-star-style pattern, and a positive change in the K value of the KDJ oscillator. It explains amplitude as a measure of activity, the candle pattern as a short-term trend cue, and rising K as a sign of strengthening upward momentum. It also gives a Python example that retrieves daily stock data, derives rolling nine-day highs and lows for KDJ, and retains candidates with positive K growth.

The post characterizes the approach as suitable for short- to medium-term use, while warning that technical filters omit fundamentals and other risks. It suggests adding technical and fundamental measures and managing holding periods and position risk. The example has unclear or inconsistent pattern conditions, an amplitude check that does not clearly implement the stated threshold, and no reported backtest or return evidence. Its claimed potential should therefore not be treated as validated performance.

Key ideas

• The screen combines price amplitude, a three-candle reversal pattern, and rising KDJ K values.
• The example calculates KDJ from daily prices using rolling nine-day highs and lows.
• The post presents the screen for short- to medium-term stock selection.
• It cautions that technical filters can omit fundamentals and expose investors to volatile stocks.
• The code and article provide no performance validation, and some conditions appear inconsistent with the stated rules.
