Stock Screening with Price Range, Shortening MACD Histogram, and Company Type

Summary

This Chinese-language note proposes screening stocks for a price range greater than one, a shortening negative MACD histogram on a 15-minute chart, and a selected company type. It frames the range as a volatility filter and the histogram condition as a possible sign that price direction is changing. Company type is intended to add industry or theme context, with the note suggesting attention to sectors, policy developments, and potentially leading or growing firms.

It provides example indicator logic and a Python sketch, but the implementations do not fully match the stated rules: the range filter in Python uses turnover ratio, and the sample data workflow does not establish a reliable market-wide 15-minute screen. No backtest, returns, or validation are reported. The note itself cautions that company classification, sector themes, and policy catalysts can change, and recommends combining technical conditions with market and fundamental analysis.

Key ideas

• The proposed screen combines a price-range threshold, a shortening negative 15-minute MACD histogram, and company type.
• The MACD condition is presented as a possible indication of a developing price change, not a confirmed reversal.
• Company type can add sector or theme context, but relying on it alone may omit other relevant factors.
• The provided code examples do not consistently implement the described range and intraday filters.
