Screening Stocks by Intraday Range, Prior Limit Status, and MACD

Summary

This post describes a Chinese equity screen combining three conditions: daily high-to-low amplitude above one percent, no upper-limit close on the previous day, and MACD below zero two sessions earlier. The proposed interpretation is that the range condition selects volatile shares, the limit-status filter avoids recently limit-up names, and the lagged MACD reading seeks stocks in a pullback. It includes indicator expressions and an illustrative Python-style workflow, but reports no backtest or performance evidence.

The author cautions that the screen omits company fundamentals, financial statements, and industry context, and may fail when markets are volatile or MACD is used poorly. Suggested refinements include adding other technical indicators, incorporating fundamental and industry factors, and tuning MACD parameters. The logic is presented as a starting point for selection rather than a validated strategy; the document supplies no evidence that its filters produce durable returns.

Key ideas

• The screen requires daily amplitude above one percent, a prior session without an upper-limit close, and MACD below zero two sessions earlier.
• The post interprets these filters as volatility selection, avoidance of recent limit-up stocks, and a search for pullbacks.
• The document gives indicator expressions and an implementation sketch but no measured results.
• Fundamental, financial, and industry information is absent from the stated core screen.
• The author suggests combining indicators and testing parameter choices, while warning of selection errors.
