A-Share Screening by Price Range, 2021 Date, and Money-Flow Strength

Summary

This A-share screen combines daily price range, a 2021 date filter, and a ranking by a measure described as capital strength. The accompanying formula defines amplitude as the high-low range divided by the low and requires it to exceed 1%, while the Python example ranks qualifying rows by a custom 14-period money-flow measure. The stated intent is to focus on volatile stocks attracting stronger recent trading interest.

The post gives no backtest, performance figures, or evidence that these conditions predict returns. Its implementations also differ: the indicator formula uses a close-to-moving-average ratio as its capital-strength proxy, whereas the Python code calculates a volume- and price-based measure. The screen omits company fundamentals and may select speculative, volatile names; its 2021 restriction also makes it a historical selection rule unless updated. The article suggests supplementing technical conditions with fundamentals and other indicators, but does not test those additions.

Key ideas

• The screen requires a daily high-low range greater than 1% of the low and restricts observations to 2021.
• The article ranks candidates by capital strength, but its indicator and Python examples use different proxies.
• The Python example sorts by a custom rolling money-flow measure after excluding zero-volume rows and bars with no price range.
• The post provides no performance evidence and warns that technical-only selection can increase speculative risk.
• The proposed improvements include adding fundamental analysis and other technical indicators.
