Screening for Consecutive Limit-Ups and Bollinger Band Position

Summary

This Chinese stock-screening proposal selects high-amplitude shares that had three consecutive limit-up sessions, then checks whether the latest close lies between the middle and upper Bollinger Bands. The post presents the sequence as a way to find active stocks with strong buying interest while requiring price to remain within part of the band. Its suggested expanded screen adds a market-value ceiling, a minimum average turnover over five sessions, and positive earnings per share. The post also recommends considering liquidity and combining technical signals with company fundamentals.

The document gives indicator formulas and sample code, but the implementation is not fully consistent with the stated rules: its consecutive limit-up calculation is simplified, and the sample data references futures despite the stock-screening context. No backtest results or evidence of predictive performance are reported. The post cautions that historical signals can become stale, a position within the Bollinger Bands does not establish undervaluation, and the filter may miss gains in a rising market. Treat the conditions as an unvalidated screening concept.

Key ideas

• The proposed screen combines high amplitude, three prior consecutive limit-up sessions, and a close between the middle and upper Bollinger Bands.
• Suggested additional filters are a market-value ceiling, five-session average turnover, and positive EPS.
• The post recommends liquidity and fundamental checks alongside technical conditions.
• The sample formulas and code do not fully match the stated stock-screening rules.
• No performance test is provided, and Bollinger position alone does not indicate fair value.
