Intraday Stock Screening with Range, Turnover, and MACD

Summary

This Chinese-language post outlines a short-term stock screen using three conditions: daily amplitude above 1, turnover between 2% and 9%, and a shrinking negative MACD histogram on a 15-minute timeframe. The intended rationale is to combine price movement and trading activity with a possible short-term momentum change. It also discusses adding fundamental measures, other technical indicators, and position controls to address the limitations of a signal-only screen.

The post includes example formulas and Python-style implementation guidance, but offers no backtest results or evidence that the rules are profitable. The implementation and verbal description do not align cleanly: the formula shown appears to detect a MACD sign transition, while the prose and example code describe a negative histogram becoming less negative. The turnover and amplitude calculations also depend on data definitions that are not clarified. The author flags overtrading, concentration, and neglect of company fundamentals as risks, so the screen is best understood as a proposed filter requiring careful definition and independent testing.

Key ideas

• The screen combines amplitude, turnover, and a 15-minute MACD histogram condition.
• The intended MACD signal is a negative histogram that is becoming shorter.
• The post recommends considering fundamentals and additional technical measures alongside the screen.
• It warns that indicator-led short-term selection can encourage overtrading or concentrated positions.
• The formula and implementation examples do not consistently express the described MACD condition.
