Chinese Stock Screen Combining Amplitude, Institutional Flow, and MACD

Summary

This Chinese-language post describes an equity screening rule that combines daily price amplitude, a proxy for changing institutional trading activity, and a MACD condition. The stated screen looks for amplitude above one, a nonzero change in the difference between current and prior institutional volume measures, and a negative MACD difference value with a rising comparison against an earlier reading. The author interprets the combination as seeking volatile stocks that may be recovering after a short-term pullback.

The post gives indicator formulas and sample code, but the code’s calculations do not clearly implement every stated condition, and no backtest or performance evidence is supplied. The author warns that the screen omits fundamentals and valuation, relies heavily on a short-term indicator, and may be too restrictive. Suggested refinements include adding other technical measures and fundamental criteria. The rule is therefore best understood as an illustrative screening idea rather than a validated strategy.

Key ideas

• The screen combines price amplitude, a proxy for institutional volume change, and a MACD condition.
• The MACD component seeks a negative reading that is improving relative to an earlier observation.
• The author presents the screen as a way to find volatile stocks that may be recovering after a pullback.
• The post provides no evidence from a backtest, and its sample code may not match the stated rule fully.
• Fundamental, valuation, and broader risk checks could complement the technical filters.
