A China Main Board Screen for Intraday Buying Pressure and Daily Gains

Summary

This document presents a daily equity screen for China’s main board. It selects stocks using three conditions: price range during the session above a stated threshold, an afternoon large-order net inflow condition, and a daily gain above a stated threshold. The accompanying indicator references express these as price and volume rules, and the post includes a Python example intended to retrieve daily data and apply the filters.

The rationale is to combine a price-range measure, a proxy for large-order activity, and recent positive performance. The post supplies no backtest results or evidence that the screen predicts future returns. Its code and indicator examples are references rather than a fully validated implementation, and the document itself flags exposure to liquidity, industry, and sector effects. It also notes that the screen omits company financial risks and suggests evaluating additional fundamental and price-volume measures, testing and revising the rules, and considering portfolio diversification. Any use requires checking the formulas and data fields against the chosen platform and dataset.

Key ideas

• The screen combines intraday range, an afternoon large-order flow proxy, and positive daily performance.
• It is intended for stocks listed on China’s main board.
• The post provides indicator formulas and a Python reference for retrieving and filtering market data.
• No backtest or performance evidence is provided, so predictive value remains unestablished.
• Liquidity, sector exposure, and omitted company fundamentals are identified as limitations.
