Shanghai-Listed Stock Screen Using Range, Volume, and Opening Gaps
Summary
The article presents a daily stock screen for securities whose codes begin with 60. It requires an intraday high-low range greater than one percent of the previous close, current volume above 10,000 lots, and an opening price above the previous close. Eligible stocks are ranked by the size of the opening gap. The article provides both indicator-formula and Python-style references for expressing the filters.
The author interprets the range and volume thresholds as signs of volatility and activity, and the positive opening gap as a possible indication of upward momentum. These are screening heuristics, not demonstrated predictive relationships: no historical results or evaluation are supplied. The text itself notes that volatile shares carry higher risk, a gap up does not ensure further gains, and the rules are simple enough to omit relevant factors. It suggests combining technical and fundamental inputs and testing alternative conditions, but does not report such optimization.
Key ideas
- The screen restricts candidates to stock codes beginning with 60.
- It requires a range above one percent of the previous close and volume above 10,000 lots.
- A gap above the previous close is used as an additional filter, and candidates are ranked by gap size.
- The article provides formula and Python-style implementations but no performance evidence.
- High volatility and opening gaps can be misleading, so the rules need broader evaluation.
