Screening Stocks for Seven Down Days and a Fresh KDJ Crossover

Summary

The document describes a stock screen combining a turnover-rate range of 3% to 12%, seven consecutive daily declines, and a newly formed bullish KDJ crossover. It presents the rules as a way to look for stocks that have fallen for several sessions but are showing a possible reversal signal. The post includes example screening logic and a Python-oriented implementation reference, though implementation details may need adjustment to match a platform’s indicator definitions and data fields.

The author cautions that a KDJ crossover can lag price action: by the time it appears, a stock may already have risen, and it can still fall sharply after selection. Suggested refinements include combining the signal with other technical indicators such as MACD, RSI, or moving averages, and adding fundamental filters such as valuation ratios. The document provides no performance tests, benchmark comparison, or evidence that these additions improve returns. The rules should therefore be treated as a proposed screening idea, not a validated trading strategy.

Key ideas

• The screen requires turnover between 3% and 12%, seven consecutive declining sessions, and a fresh bullish KDJ crossover.
• The crossover is intended to identify a potential reversal after a sustained decline.
• KDJ signals may lag and do not prevent further losses after a stock is selected.
• The author proposes adding other technical indicators or fundamental filters for further screening.
• The document supplies no backtest or evidence of profitability.
