Screen Chinese Stocks for High Amplitude and Shortening MACD Bars

Summary

This proposed stock screen combines an amplitude threshold, a shortening negative MACD histogram on a 15-minute chart, and a stock-code prefix. The stated rationale is to find volatile shares whose downside momentum may be easing, then focus the search on a particular Chinese market segment. The document also suggests adding volume, turnover, and other technical measures such as KD crossovers or RSI for further filtering.

The screen is described conceptually and accompanied by example formulas and Python-like reference logic, but it provides no backtest results or evidence that the conditions predict a reversal. The code examples also appear internally inconsistent: the code prefix described as identifying the target board is questionable, and the code's amplitude calculation and histogram period handling do not clearly match the written conditions. The proposed screen should therefore be treated as an unvalidated starting point; verify market classifications, data frequency, signal timing, and selection rules before evaluating it.

Key ideas

• The proposed screen combines a high-amplitude condition with a shortening negative MACD histogram on a 15-minute interval.
• A stock-code prefix is intended to restrict the universe to a specific Chinese market segment.
• The document suggests adding volume, turnover, and other indicators to refine the selection.
• It gives no performance evidence, and its examples contain inconsistencies that require verification.
