Screening Stocks for Volatility, Weekly MACD, and a Prior Limit-Down Open

Summary

This Chinese stock-screening note combines three conditions: daily trading range above one percent of the previous close, weekly MACD above zero, and a prior-day 9:15 matching price at the lower price limit. It presents the screen as a way to find stocks that experienced a sharp move while retaining a positive weekly trend, with a possible rebound as the motivating hypothesis. It also sketches indicator formulas and an example workflow for screening a stock universe.

The document gives no performance data or backtest results, and its example code does not consistently implement the stated weekly MACD condition. It cautions that the screen omits company fundamentals, that a limit-down indication does not imply a rebound, and that selections may be unstable or risky. It suggests combining technical, fundamental, market sentiment, and flow measures, then validating the resulting rules with historical analysis and stronger risk controls.

Key ideas

• The screen requires a daily high-low range above one percent of the previous close and weekly MACD above zero.
• It also selects stocks whose previous-day 9:15 matching price reached the lower price limit.
• The proposed rebound rationale is a hypothesis rather than a result supported by reported performance evidence.
• The note warns that technical conditions omit fundamentals and cannot ensure a rebound or stable future behavior.
• It recommends adding other data and validating the rules through statistical analysis and backtesting.
