Screening Stocks for Wide Ranges, Turnover, and Rising Lows

Summary

This Chinese-language post outlines an equity screening rule that combines a wide daily trading range, the previous day's actual turnover within a stated band, and a rising-bottom price pattern. The rationale is that elevated movement and trading activity may signal changing participation, while rising lows alongside rising highs may indicate a developing upward reversal. It provides example formulas for applying these conditions and references rolling windows for evaluating recent highs and lows.

The post cautions that the screen relies heavily on price and trading behavior, may favor short-term speculation, and cannot ensure that a reversal will continue. It suggests adding other indicators, checking data quality, adjusting the observation span, and considering fundamentals. The formulas are presented as references rather than a complete validated system; the post supplies no backtest results, transaction costs, or out-of-sample evidence. The stated thresholds and pattern definitions should therefore be treated as screening choices that require independent testing.

Key ideas

• The screen combines a wide price range, bounded prior-day turnover, and rising highs and lows.
• Rising bottoms are treated as a possible reversal clue, not a guarantee of continued gains.
• The post offers example indicator formulas but gives no performance evidence.
• It identifies short-term speculative bias and data reliability as limitations.
• Additional indicators, adjusted history windows, and fundamental context are suggested for refinement.
