Stock Screening with High Amplitude, Volume, Opening Strength, and Order Book Imbalance

Summary

This Chinese-language post presents an A-share stock screen using four conditions: price amplitude above a threshold, current trading volume above a threshold, an opening price above the previous close, and best bid volume greater than best ask volume. The proposed rationale is to find volatile stocks showing opening strength and apparent buying pressure. It suggests combining the screen with indicators such as MACD, KDJ, and RSI, as well as company and industry analysis.

The post includes a formula reference and a Python example intended to retrieve stock data and filter candidates. However, the example's checks do not clearly implement every stated condition, and it reports no backtest or trading results. The author notes that technical signals omit fundamentals and that bid volume exceeding ask volume does not guarantee a price rise. The selection thresholds and order book comparison should therefore be treated as screening ideas requiring validation, not as a tested trading strategy.

Key ideas

• The screen combines price amplitude, trading volume, a gap up at the open, and greater best bid than ask volume.
• The rationale is to select volatile stocks with signs of price strength and buying pressure.
• The post suggests adding momentum indicators and company or industry analysis.
• Order book imbalance alone does not establish that a stock has further upside.
• The examples provide no measured strategy performance and may not implement every stated condition consistently.
