Screening Stocks with Amplitude, Control and 15-Minute MACD

Summary

The document outlines a short-term stock screen combining daily amplitude above 1, a “today control” measure above 21, and a 15-minute MACD condition described as shortening green histogram bars. It presents example implementations for a Chinese stock platform and Python, where the latter checks amplitude, a controlling-shareholder percentage change, and a comparison between MACD readings. The accompanying discussion suggests that the screen aims to find volatile stocks with concentrated control and a possible short-term entry signal.

The explanation is internally inconsistent: it refers to fewer red histogram bars as a possible buy opportunity, while the stated rule specifies shrinking green bars, and the code compares MACD values rather than directly measuring histogram bar length. No performance results or validation are provided. The text warns that short-interval MACD can be noisy and lagging, and proposes adding technical and fundamental filters plus evaluating strategy statistics. These are suggestions rather than tested improvements; the screen alone does not establish an edge or address execution and risk controls.

Key ideas

• The screen combines a daily amplitude threshold with a measure of controlling-shareholder change and a 15-minute MACD condition.
• The example code implements the MACD condition through a comparison of readings, which may not match the verbal description of shrinking histogram bars.
• The document proposes adding other technical signals and fundamental measures, but gives no test results for those additions.
• Short-interval MACD signals may be noisy and lagging, according to the document.
