Screening Stocks for Large Range, Turnover, and Reversal Candles

Summary

This Chinese-language post proposes screening stocks using three conditions: a large daily price range, prior-day turnover within a specified band, and a reversal candle pattern. It presents the combination as a way to find stocks with substantial price movement and selected trading activity that may be candidates for reversal. The post includes example indicator-formula and Python snippets intended to illustrate the screen.

The author cautions that the approach depends heavily on individual stocks’ price movement and trading behavior, which can create market risk. Suggested additions include moving averages, relative strength, sector information, and fundamental factors. The examples are not a tested strategy: the post provides no returns, benchmark comparison, or risk-adjusted results, and the code’s turnover and candle-condition references are not fully consistent across sections. The screen therefore needs careful data and logic validation before use.

Key ideas

• The proposed screen combines a large daily range, a bounded prior-day turnover measure, and a reversal candle condition.
• The post offers both indicator-formula and Python examples of the screening logic.
• The author identifies dependence on individual stock behavior as a source of market risk.
• Additional technical, sector, and fundamental inputs are suggested as possible refinements.
• The examples provide no performance evidence and contain differences that require validation.
