Chinese Stock Screen Using Amplitude, Shrinking MACD Bars, and Large-Order Flow

Summary

This Chinese-language screen combines three conditions: stock amplitude above 1, a shrinking negative MACD histogram on a 15-minute chart, and net large-order volume above 0.05 for at least three consecutive days. The proposed interpretation is that elevated movement identifies active stocks, shrinking negative MACD bars may signal a possible turn, and persistent positive large-order flow may indicate continuing inflows. The document also suggests adding market themes, leading stocks, industry trends, and broader economic context.

It warns that the screen depends heavily on readings of institutional or major-player flows, which can be uncertain and subjective, and may miss other promising stocks. Example indicator formulas and a Python workflow are included, but the examples refer to particular data sources and contain details that may not align cleanly with the stated conditions. No historical performance, transaction costs, or validation results are provided, so the claimed potential for improved selection accuracy is not demonstrated.

Key ideas

• The screen requires amplitude above 1, a contracting negative 15-minute MACD histogram, and positive large-order net volume over at least three days.
• The proposed rationale combines volatility, a possible momentum shift, and persistent buying flow.
• The document recommends considering market themes, leading stocks, industry trends, and economic conditions as additional context.
• Large-order flow can be difficult to interpret and may introduce selection bias.
• The example formulas and code are not accompanied by backtest or validation results.
