A-Share Screening with Positive MACD and Large-Order Flow

Summary

This A-share stock screen selects candidates after each trading day using a positive MACD condition, then ranks stocks by reported popularity and by the product of percentage price change and a large-order volume measure. The document explains the rationale: positive MACD is intended to indicate an upward trend, popularity reflects market attention, and the flow term is meant to highlight stocks drawing large-order activity. It includes indicator and screening examples, but the stated large-order calculation is a sum of positive volume rather than a clearly defined net-flow measure, so the implementation may not match the strategy description.

The author warns that short-term flow and price changes do not establish fundamental value or guarantee that selected stocks will lead future returns. The article provides no backtest results or evidence that the screen works. It suggests adding fundamental and technical filters, using broader flow measures, and researching companies after screening. Its examples should therefore be treated as illustrative and checked for data definitions and practical execution constraints before evaluation.

Key ideas

• The screen requires MACD to be above its zero line.
• Candidate stocks are ordered by popularity and by price change multiplied by a large-order volume measure.
• The proposed selection runs after each trading session.
• The document cautions that short-term price and flow signals can misidentify future leaders.
• Its sample volume calculation may not represent net large-order flow as described.
