Chinese Stock Screen Using 15-Minute MACD Contraction and Trading Activity

Summary

This Chinese stock-screening article combines a price-amplitude filter, trading volume above 10,000 lots, an opening price above the prior close, and a 15-minute MACD condition intended to identify shrinking bearish momentum. It presents the screen as a way to find active stocks with a possible buy signal. The indicator formula also specifies MACD line and signal-line relationships and compares prior histogram values; the accompanying prose describes a shorter green histogram as the signal. These details make the screen more specific than a general MACD suggestion, though the article does not establish that the conditions predict profitable trades.

The author flags noise, uncertainty, overfitting, and delayed MACD signals, and suggests comparing other indicators or fundamental measures. No performance results or systematic validation are provided. The Python example appears inconsistent with the stated selection logic, including its price comparison and MACD conditions, so it should not be treated as a faithful implementation without review. The post is best read as a proposed technical screening rule, not evidence of an independently tested strategy.

Key ideas

• The screen requires amplitude above one, volume above 10,000 lots, and an opening price above the previous close.
• It uses 15-minute MACD conditions to identify a possible reduction in bearish momentum.
• The article warns that noisy data, overfitting, and delayed indicator signals can weaken the screen.
• No backtest results are supplied, and the sample Python logic may not match the described conditions.
