Screening Shanghai-Listed Stocks by Daily Range and Weekly Bullish Candles

Summary

This Chinese equity screen looks for stocks whose codes begin with 60, whose daily high-to-low range exceeds 1% of the opening price, and whose weekly candle is bullish, meaning the weekly close is above the weekly open. The article’s example also sorts results by trading amount. It supplies a platform formula and a Python-style selection example, illustrating how the conditions can be combined into a stock list.

The article interprets a larger daily range as greater movement and a bullish weekly candle as a sign of recent upward direction. It also notes that a short-term candle may miss the longer-term trend, that code-prefix and range filters can generate many unhelpful candidates, and that technical-only selection may overlook fundamentals. It suggests adding other technical and fundamental analysis. No backtest, benchmark, or performance evidence is included, and the examples do not establish that the screen predicts future gains.

Key ideas

• The screen requires a daily high-to-low range greater than 1% of the opening price.
• It limits candidates to stock codes beginning with 60 and a bullish weekly candle.
• The example sorts qualifying stocks by trading amount.
• The author cautions that short-term candles and technical filters can overlook broader trends and fundamentals.
• No evidence is provided that the screening conditions generate positive returns.
