Screening Chinese Equities by Range, Large-Order Flow, and Turnover

Summary

This Chinese-language article outlines an equity screening approach based on intraday price range, a ranking for net large-order volume, and high turnover on the prior day. The rationale is that volatile, actively traded stocks with substantial trading activity may offer potential upside. It also includes sample platform and Python selection logic, but the code’s conditions do not consistently match the stated screen: the large-order ranking is approximated with other data, and turnover conditions differ across sections.

The article cautions that the screen relies on short-term technical and trading-activity measures and omits long-term fundamental strength. It says narrow criteria may limit the eligible universe, suggests combining technical and fundamental measures or adjusting thresholds, and recommends backtesting. No test results, risk-adjusted returns, or evidence of profitability are reported, so the proposed upside rationale remains unvalidated.

Key ideas

• The screen combines price range, large-order activity, and recent turnover to select equities.
• The article links these measures to volatility and trading activity as possible indicators of upside potential.
• Its sample code does not fully implement the described large-order ranking and turnover rules.
• The approach omits fundamental analysis and may produce a narrow selection universe.
• The article recommends adjustment and backtesting but reports no performance results.
