Chinese Stock Screen for Seven Losing Sessions and Reversal Signals

Summary

This Chinese-language post proposes an equity screen combining daily range, a reversal or engulfing-style condition, and a run of seven declining sessions. Its expanded version adds a bullish moving-average crossover, trading volume above its five-day average, and a limit on the stock’s premium to its 60-day average. The post includes example indicator formulas and a Python-style outline for selecting and ranking stocks.

The author argues that combining price action and activity filters may reduce noise, while acknowledging that the screen ignores broader market and policy conditions. It also warns that stocks with extended losing streaks may rebound sharply. The article offers no performance results or validation methodology, and its descriptions of the reversal and seven-session conditions are not fully consistent across the prose and examples. Treat the formulas as a starting point that requires careful definition and testing, rather than as evidence of a profitable strategy.

Key ideas

• The initial screen combines a daily range threshold, a reversal pattern, and seven consecutive declining sessions.
• The proposed expanded screen adds moving-average, volume, and price-deviation filters.
• The post provides formula examples and a high-level outline for implementing a stock selector.
• The author notes that market and policy conditions are omitted and that long losing streaks can precede sharp rebounds.
• No backtest evidence is given, and some signal definitions vary between the descriptions and examples.
