A-share Stock Screen Using Turnover, Relative Gains, and 15-Minute MACD

Summary

This Chinese-language post proposes screening mainland Chinese main-board stocks for turnover between 3% and 12%, a daily gain above 1% relative to a comparison benchmark, and a 15-minute MACD condition described as the histogram’s green bars shortening. It provides example logic in a charting formula and Python, then suggests ranking candidates and using a template for backtesting.

The post frames the MACD filter as a way to identify a possible easing of short-term weakness, while warning that MACD can mislead and that a short intraday interval may be noisy. It suggests combining other technical or fundamental measures or using a longer MACD interval. The examples contain apparent implementation inconsistencies, including a mismatch between the stated comparison with same-sector stocks and the Python benchmark comparison, so the screen needs careful verification before testing or use.

Key ideas

• The screen combines turnover, daily price performance, board eligibility, and a 15-minute MACD condition.
• The MACD condition is intended to identify shortening negative momentum bars.
• The post warns that MACD can generate false signals and that short intervals can amplify noise.
• It proposes adding other technical or fundamental measures or using a longer MACD interval.
• The code examples should be checked because some implementation details do not match the stated selection logic.
