Chinese Stock Screen Using Intraday MACD and KDJ Conditions

Summary

This stock screen combines three technical conditions: amplitude above 1, a shrinking negative MACD histogram on a 15-minute interval, and growth in the KDJ K value. The document interprets these as filters for active stocks, possible momentum shifts, and strengthening direction. It also provides indicator formulas and a sample Python workflow that applies amplitude and MACD filters, calculates KDJ values, and sorts candidates by trading amount.

The source warns that strict filters may exclude potential candidates and that technical indicators can overlook company fundamentals. It suggests adding fundamental measures and other technical indicators, such as valuation ratios, RSI, or moving averages. The sample code has apparent inconsistencies: it uses turnover ratio as an amplitude proxy, mixes daily and weekly calculations, and merges data in ways that may not align by stock and date. No historical performance, transaction costs, or risk-adjusted results are reported, so the screen should be treated as an illustrative selection rule rather than a validated strategy.

Key ideas

• The screen requires amplitude above 1, a shortening negative MACD histogram on a 15-minute interval, and an increasing KDJ K value.
• The source associates these conditions with volatility, a possible momentum change, and strengthening price direction.
• The example code filters and ranks stocks but does not demonstrate that the screen is profitable.
• The document recommends combining technical signals with fundamental analysis and other indicators.
• The code’s timeframe and data-alignment inconsistencies limit its usefulness without careful correction.
