Stock Screening with Price Range, Trading Volume, and a High Open

Summary

The document proposes a Chinese equity screen based on daily price movement, trading volume, an opening-price condition, and a fixed price level. Its narrative describes selecting stocks with an amplitude above 1, current volume above 10,000 lots, a high open, and a price of 18.5 yuan. It presents volatility as a way to find active shares and volume as a rough liquidity indicator, then suggests combining the technical filters with company fundamentals and industry information.

The post warns that price and volume signals alone omit business quality and other market factors, and that fluctuating activity creates risk. It includes formula and Python examples, but the details do not consistently encode the stated screen: the formula compares the open with the prior open, while the prose calls for a high open; the code also checks an opening price of 18.5 rather than the described closing or share price. No backtest results or evidence of predictive value are presented, so the proposal remains an unvalidated screening heuristic.

Key ideas

• The narrative screen uses price amplitude, current volume, a high open, and a fixed price of 18.5 yuan.
• The post treats higher volume as a rough sign of liquidity and larger price movement as a sign of activity.
• It recommends adding fundamental and industry information to a technically focused screen.
• The examples do not consistently match the prose about the opening condition and price level.
• No backtest or performance evidence is provided.
