Chinese Stock Screening with Intraday Inflow, Range, and Price Filters

Summary

This stock screen selects equities using three conditions: daily amplitude above 1 percent, an afternoon large-order net inflow condition, and a recent low price below 20 yuan. The accompanying explanation treats these as proxies for volatility, capital flow, and a lower share price, then recommends checking company finances and operations before treating a selected stock as an investment candidate. It also suggests considering additional indicators, diversification, and risk controls.

The document includes formula references and a Python example intended to retrieve stock data and apply related filters. However, the example uses average range and price measures in places where the stated rule is framed as a daily threshold, and its flow proxy is not clearly tied to afternoon activity. It also lacks a specified lookback length for the recent-low condition in the prose, even though the example uses a period. No backtest, benchmark, or evidence of predictive value is reported; the post explicitly warns that simple filters can misidentify future winners and miss alternatives.

Key ideas

• The screen combines a daily amplitude threshold, a large-order inflow proxy, and a recent low-price filter.
• The stated rationale links the filters to volatility, capital flow, and share price.
• The post recommends further company analysis and risk management after screening.
• The code example does not fully match the prose definitions of the filters.
• No empirical performance evidence is supplied, and the author cautions that the rules are simple.
