MACD and Prior-Day Price Conditions for Chinese Stock Screening

Summary

This Supermind community post describes a stock-selection rule combining MACD above the zero line, a favorable company classification, and a prior-day 9:15 matching price said to be at the daily limit-down level. It includes formula and Python examples intended to filter securities using company financial data and minute prices, then select a small candidate list. The approach is presented as a mix of technical, company-related, and recent price conditions.

The post does not report a backtest, returns, or evidence that the filters improve performance. It notes that MACD is not reliable in every market, a favorable company classification does not establish sound finances, and a limit-down event cannot ensure a stable recovery. The examples also appear to use low-price comparisons that may not faithfully represent the stated 9:15 matching-price condition. That event definition and the code’s data handling would need verification before interpreting or applying the screen.

Key ideas

• The proposed stock screen requires MACD above zero, a favorable company classification, and a prior-day price condition.
• The author presents technical, company-related, and recent trading filters as complementary inputs.
• The post supplies formula and Python examples but no performance evidence.
• The author warns that each filter is an incomplete measure and does not guarantee future stability.
• The code’s low-price logic may not match the stated 9:15 matching-price condition.
