Chinese Stock Screening with Afternoon Large-Order Inflows and Price Amplitude

Summary

This Chinese equity screening idea selects stocks with price amplitude above 1%, positive afternoon large-order net inflow, and an exclusion for companies categorized in Beijing. The post treats amplitude as a sign of active price movement and the order-flow condition as a possible indicator of buying pressure. It provides formula and Python examples that use price and volume data alongside a regional field.

The document cautions that these short-term signals do not capture a company's finances or longer-term operating prospects, and that excluding stocks by region may remove capable firms without a clear investment rationale. It recommends further financial and operating analysis and stronger risk controls, including attention to exits and capital management. The sample implementation's conditions are not a direct, clearly time-specific measure of afternoon order flow, and the post offers no backtest or performance evidence. The screen should therefore be read as a rough candidate filter rather than a validated trading strategy.

Key ideas

• The screen combines price amplitude above 1%, afternoon large-order net inflow, and exclusion of Beijing-listed stocks.
• The proposed signals focus on price movement, trading flow, and a geographic filter rather than company fundamentals.
• The regional exclusion lacks a stated investment rationale and may remove otherwise suitable stocks.
• The code example does not clearly establish an afternoon-only order-flow calculation, and no performance results are supplied.
• The author recommends additional company analysis and risk controls before trading.
