A-Share Stock Screen Using Daily Range and a Price Threshold

Summary

This community post describes a simple A-share stock screen using a daily price-range threshold, a specified closing-price level, and a relationship to the five-day moving average. The stated rationale is to combine a volatility condition, a price filter, and a short-term trend signal. It also suggests extending the screen with volume and price indicators or fundamental measures, and cautions that a small set of technical rules omits company quality and other risks.

The post provides indicator and Python examples, but the implementation is not fully consistent with its prose: the stated moving-average condition says price should be above the five-day average, while the displayed formula checks whether the average is above the close. The Python example also does not clearly implement all the stated criteria. No backtest results or performance evidence are supplied, so the screen should be treated as an illustrative rule set rather than a validated strategy.

Key ideas

• The proposed screen combines a daily range filter, a specific closing-price threshold, and a five-day moving-average condition.
• The post frames the range as a volatility measure and the moving average as a short-term trend filter.
• It recommends considering additional technical or fundamental inputs, while noting that the basic screen omits company quality.
• The prose and displayed formula disagree about whether the close should be above or below the five-day average.
• The document supplies no performance evidence to establish that the screen is profitable.
