Stock Screening with Institutional Buying and Shortening MACD Bars

Summary

This Chinese-language post proposes a stock screen combining three signals: today’s increase in holdings above five percent, an institutional buying indication, and shortening green MACD bars on a 15-minute chart. It interprets the first two as evidence of buying interest and the shorter bars as potentially improving sentiment. The stated selection logic combines these filters and suggests adding other technical and market data, along with stop-loss and take-profit levels.

The post warns that the buying signals can be false and that shorter MACD bars may reflect a bounce within a continuing downtrend rather than a reversal. It includes sample code, but the code does not implement the full stated screen: its combined condition multiplies the net-flow ratio by the institutional indicator, while it calculates but does not use the MACD output. No backtest, execution details, or measured results are supplied. The screen therefore remains a proposed heuristic whose data definitions and signal behavior would need careful validation.

Key ideas

• The proposed screen combines a holdings increase above five percent, institutional buying, and shortening 15-minute MACD green bars.
• The post treats these conditions as possible signs of buying interest and improving sentiment.
• It warns that the buying signals can be false and that MACD improvement may be a temporary bounce.
• The sample code does not implement all three stated conditions because it does not use its MACD calculation.
• The post recommends broader analysis and stop-loss and take-profit controls, but supplies no performance evidence.
