A Stock Screen Using Weekly MACD, Daily Range, and Prior-Day Limits

Summary

This Chinese-language post describes a stock selection rule combining daily price range, weekly MACD, and the prior day's price limit status. It seeks stocks with a daily high-low range above 1% of the previous close, weekly MACD above zero, and a prior session that did not close at the stated limit threshold. The post presents these conditions as a way to identify an upward trend while avoiding stocks that have already surged to the limit.

The article also gives formula and Python examples, though the code's data fields and date handling are not fully aligned with the stated rules. It provides no backtest results or performance evidence. The author notes that technical indicators omit company fundamentals and sector conditions, and suggests adding financial metrics and risk controls. The screen is therefore an illustrative technical filter, not a demonstrated source of returns; its thresholds and implementation would need validation against the intended market's trading rules and data.

Key ideas

• The screen requires a daily high-low range exceeding 1% of the previous close.
• It selects stocks whose weekly MACD is above zero.
• It excludes stocks that closed at the stated price-limit threshold on the prior day.
• The post offers formula and Python examples but gives no performance test results.
• Technical filters can miss fundamental and sector influences, so the author recommends further screening and risk controls.
