Combining Daily Amplitude, Weekly MACD, and Company Type in Stock Screening

Summary

This Chinese-language post outlines an equity screen that combines a daily price-range condition, a weekly MACD condition, and a filter for selected company types. It describes amplitude as the high-low range relative to the previous close, and requires weekly MACD to be above zero with its line above the signal line. The company-type condition is presented as a list-based classification filter. The examples mention financial and pharmaceutical industries, and suggest applying further fundamental analysis after screening.

The post gives formulas and a sample data workflow, but it does not provide a tested portfolio, performance results, or a complete operational specification. Its code example uses an average daily range-to-close calculation, which is not identical to the stated daily amplitude condition, and the weekly MACD requirement is not clearly implemented in that example. The author notes that a narrow or broad company classification can respectively reduce the candidate pool or admit lower-quality firms, and suggests adding other fundamental and market factors.

Key ideas

• The screen combines a daily amplitude threshold with weekly MACD and a company-type filter.
• The stated MACD condition requires the indicator to be positive and above its signal line.
• The company classification filter can narrow the universe or include firms of uneven quality.
• The example code does not fully match the stated screening logic, so implementation details need checking.
• The post recommends further fundamental review but provides no backtest evidence.
