Screening Stocks by Trading Range, Large-Order Flow, and the Ten-Day Average

Summary

This Chinese-language post describes a stock-selection screen using three conditions: amplitude above 1, large-order net volume above 0.05 for at least three consecutive days, and an opening price near the ten-day moving average. The stated proximity band places the open within five percent above or below that average. The rationale is to combine recent trading activity with a price-location filter.

The post gives example indicator formulas and Python-style code, but the implementations are not fully consistent with the prose: the example range calculation and filtering expressions may not directly implement the stated conditions. It provides no backtest, selected-stock results, or evidence that the screen improves returns. The author notes that relying heavily on technical measures can mislead and suggests combining them with fundamental indicators. Market conditions can change, and the screen alone does not address position sizing, exits, or portfolio risk.

Key ideas

• The screen combines amplitude, positive large-order net volume, and opening price near the ten-day average.
• The stated large-order condition requires a positive net-volume measure over at least three consecutive days.
• The opening price filter allows a band around the ten-day moving average.
• The code examples may not exactly match the stated screening logic.
• The post recommends considering fundamental measures and acknowledges that market conditions can change.
