Intraday Stock Screening with Large-Order Flow and Weakening MACD Bars

Summary

This short-term Chinese stock screen combines daily price amplitude above 1%, a high ranking on large-order net volume, and a 15-minute MACD histogram that is negative but shrinking. The intended interpretation is that substantial trading activity and a contracting negative histogram may help identify stocks whose short-term downward momentum is easing. The article gives indicator formulas and sample Python code, and says candidates can be sorted by trading amount. The examples are illustrative; the Python sample uses daily data and does not clearly implement a 15-minute series, so it does not demonstrate the stated timeframe consistently.

The article offers no backtest, measured outcomes, or evidence of predictive accuracy. It cautions that a technical-only screen can miss fundamentals and broader market conditions, and that MACD is lagging and sensitive to the chosen window. It recommends combining the signals with other analysis and risk controls, including stop-loss and take-profit rules. The method should be validated with correctly aligned intraday data before practical use.

Key ideas

• The screen requires daily amplitude above 1% and a high large-order net-volume ranking.
• It looks for a negative 15-minute MACD histogram that is contracting.
• The article supplies formula and code examples, but its Python example does not clearly use 15-minute data.
• The author notes that technical signals can lag and omit fundamentals or wider market context.
• No performance test is presented, and risk controls are recommended.
