Rising-Low Stock Screen with KDJ Momentum and Bollinger Exit

Summary

This Chinese stock-screening example combines price amplitude above 1 with a rising price base and improving KDJ momentum. The stated refined rules also call for the K line to cross above the D line with at least a 1% daily increase, exclude specially treated stocks, and exit when the K line or closing price falls below the Bollinger middle band. The article provides indicator formula and Python examples, and suggests adding valuation or fundamental measures to broaden the analysis.

The document identifies dependence on KDJ as a limitation: broad market moves can affect its signals, while price patterns and oscillators do not measure company value. It offers no backtest or performance results. The code snippets also contain ambiguities and inconsistencies with the prose, including differently expressed KDJ conditions and a Python exit calculation that does not directly mirror the stated exit rule. The screen is therefore an illustrative technical strategy whose definitions and implementation need checking before evaluation.

Key ideas

• The screen combines amplitude, rising lows, and strengthening KDJ momentum.
• The proposed rules exclude specially treated stocks and use the Bollinger middle band as an exit reference.
• The article flags market-wide interference and missing company valuation analysis as limitations.
• The code and written rules are not fully consistent, and no performance evidence is reported.
