A-Share Screen Using Price Range, K Threshold, and Shortening MACD Bars

Summary

This proposed stock screen combines a price-amplitude threshold, a K-line value below 20, and shortening MACD histogram bars on a 15-minute timeframe. The accompanying discussion interprets the K-line condition as oversold and the shrinking histogram as a sign associated with a declining market, then suggests using the combination to filter stocks. It warns that short-timeframe MACD can be noisy and produce false signals, and recommends considering additional indicators or timeframes.

The document provides sample formula and Python implementations, but they do not clearly match the stated screen: the shown conditions use moving-average comparisons and MACD references, including a positive MACD requirement, rather than explicitly implementing all three headline conditions. No historical test, performance measure, or transaction-cost analysis is reported. The proposed logic should therefore be treated as an unvalidated screening idea, and its interpretation and implementation require careful reconciliation before use.

Key ideas

• The stated screen combines price amplitude, a K-line threshold, and a 15-minute MACD histogram condition.
• The text associates the K-line threshold with oversold conditions and shortening MACD bars with a declining market.
• The author cautions that short-period MACD can be noisy and generate false signals.
• The provided formula and Python example do not transparently implement every stated screening condition.
• No backtest evidence is supplied to establish the screen’s effectiveness.
