Screening Shanghai-Listed Stocks by Range and Prior-Day Top-Trader Lists

Summary

This A-share screening idea selects stocks whose daily high-to-low range exceeds 1% of the opening price, whose codes begin with 60, and which appeared on the prior day’s top-trader list. The example code further filters for stocks near the upper end of their 50-period high-low range and ranks candidates by that position. The post describes the list appearance as a sign of investor attention, while acknowledging that it does not guarantee favorable performance.

The author warns that large ranges can bring greater risk and recommends combining the screen with fundamental information and other technical measures. The post supplies no backtest, outcome data, or detailed rationale for the added 50-period ranking threshold. It also does not specify how the top-trader list data is sourced or handled, so implementation depends on data availability and definitions. The criteria should be treated as a screening example, not evidence of a validated trading strategy.

Key ideas

• The initial screen requires a daily high-low range above 1% of the opening price, a code beginning with 60, and a prior-day top-trader-list appearance.
• The example code ranks qualifying stocks by their position within a 50-period high-low range.
• Top-trader-list inclusion may indicate attention but does not ensure positive performance.
• High price ranges can increase risk, and the post recommends additional analysis.
• No backtest or measured results are provided.
