Chinese Stock Screen Using Range, Prior-Day Control, and Afternoon Large-Order Flow

Summary

The document describes a short-term Chinese equity screen combining three conditions: price amplitude above a stated threshold, evidence of main-force control on the prior day, and positive net flow from large orders in the afternoon. Its accompanying sample code adds further filters, including trading activity, turnover, valuation fields, market capitalization, special-treatment status, price movement, and a comparison of afternoon with morning order flow. The stated concept is to select stocks with notable price movement and buying pressure.

No backtest, trade record, or performance statistics are provided, so the screen’s effectiveness is unestablished. The document itself cautions that the selection logic is simple, omits broader technical and fundamental information, and may be especially vulnerable to price swings when afternoon volume is thin. The code is presented as a reference and its detailed filters do not cleanly demonstrate the full named logic, including how prior-day control is measured. It suggests adding indicators, financial measures, industry context, and further checks before trading.

Key ideas

• The core screen combines elevated price amplitude, prior-day main-force control, and positive afternoon large-order flow.
• The sample implementation applies additional activity, valuation, capitalization, and price filters.
• The document provides no performance evidence to establish whether the screen is profitable.
• Thin afternoon trading can make large orders more disruptive to prices.
• Broader technical, fundamental, and market context could supplement the narrow conditions.
