Stock Screening With Rising Lows and Shortening MACD Histogram Bars

Summary

This stock-selection idea combines three conditions: an amplitude measure above a stated threshold, a rising price bottom, and shortening green bars in the 15-minute MACD histogram. The article frames amplitude and rising lows as ways to identify active stocks whose lows are improving, while the MACD condition is intended to capture a change in short-term momentum. It provides example screening logic for a Chinese stock platform and a Python-style implementation, although the code’s rolling-window parameters are left unspecified.

The article warns that broad market conditions can affect selections and that MACD may lag, potentially missing opportunities or signaling unsuitable stocks. It suggests adding trend measures or fundamental data to refine the screen, but provides no backtest, trade rules, or performance evidence. The written condition and code examples also do not align cleanly in their MACD sign and histogram tests, so the exact operational definition should be checked before use.

Key ideas

• The screen requires amplitude above a threshold, rising lows, and shortening green MACD histogram bars on a 15-minute timeframe.
• The article supplies platform formula and Python-style examples, but leaves key window parameters undefined.
• Market conditions can affect results, and MACD signals may lag price changes.
• The article proposes adding trend or fundamental filters but reports no strategy performance.
• The prose and code express the MACD conditions inconsistently, so implementation requires clarification.
