A-Share Screening with RSI, Order Flow, and Weekly MACD

Summary

This document outlines a technical A-share screen using RSI below a threshold, an external-to-internal trading volume ratio above a threshold, and a positive weekly MACD histogram. The accompanying explanation interprets the RSI condition as avoiding an overbought reading, the volume ratio as a sign of buying interest, and the weekly histogram as evidence of upward momentum. The example code adds a recent price-change filter and checks for an improving weekly histogram, but these details make the implementation more specific than the headline rule.

The post offers indicator setup guidance and names possible fundamental additions such as valuation and profitability measures. It warns that technical signals can be short-lived, vulnerable to false breaks, and incomplete without fundamental analysis; it also notes possible measurement error in the volume ratio. No backtest results or demonstrated returns are given, so the screen should be read as a proposed selection method rather than an evidenced strategy.

Key ideas

• The screen combines a sub-threshold RSI, a high external-to-internal volume ratio, and a positive weekly MACD histogram.
• The example implementation adds a recent price-change check and requires the weekly histogram to improve.
• The stated rationale is to combine buying activity with upward momentum while avoiding an overbought reading.
• Technical signals may be temporary, prone to false breaks, and affected by volume-ratio measurement error.
• The document provides no performance test and suggests considering fundamental measures as additional filters.
