A High-Range, Elevated-Volume, Three-Limit-Up Stock Screen

Summary

This Chinese equity screening idea combines a daily high-low range of at least 1%, a volume ratio between 1.5 and 6, and a requirement that the stock had three consecutive limit-up closes on the prior days. The article presents the range and volume conditions as filters for active trading and uses the recent price surge to target short-term momentum. It supplies indicator-formula and Python examples, but reports no backtest, return, or other outcome evidence.

The proposal is aimed at volatile short-term markets and carries substantial event and reversal risk: recent limit-up streaks can be vulnerable to sector rotation, changes in market style, and shifts in expectations. It also omits macroeconomic, industry, and company-quality analysis. The implementation examples do not cleanly establish the stated volume-ratio calculation, so the signal definitions should be checked against the intended data source. The article recommends broader analysis and risk controls; the screen should be treated as an unvalidated high-risk filter rather than a demonstrated strategy.

Key ideas

• The screen requires a daily range of at least 1% and a volume ratio from 1.5 to 6.
• It also selects stocks with three consecutive limit-up closes on the preceding days.
• The article positions the rule for short-term, high-volatility markets and highlights heightened risk.
• No performance validation is provided, and the example volume calculations may not match the stated ratio.
