Intraday MACD and Buyer-Seller Pressure for Chinese Stock Selection

Summary

The proposed screen combines three conditions: MACD above zero, an external-to-internal trading volume ratio above 1.3, and a shortening MACD histogram on a 15-minute chart. The article frames these as a broad positive trend, stronger buying pressure, and a possible intraday shift in momentum. It also describes the approach as technical-only and suggests combining it with fundamental measures or other indicators and limiting the number of selected stocks.

The article warns that technical indicators may overlook company fundamentals and may react inadequately when market conditions change. It offers formula and Python references, but these do not establish that the strategy works: no backtest, performance data, transaction-cost analysis, or complete execution rules are included. The sample’s volume-ratio calculation and time-series indexing also appear questionable, and “green bar shortening” needs a precise sign and comparison convention. Those details should be resolved before the rule is evaluated.

Key ideas

• The screen requires MACD above zero, an external-to-internal volume ratio above 1.3, and a shortening 15-minute MACD histogram.
• The conditions are intended to combine trend, buying pressure, and intraday momentum change.
• The article cautions that technical-only selection can miss fundamental risks and market regime shifts.
• It proposes adding fundamental or technical filters and capping the number of picks.
• No strategy performance evidence is provided, and the sample calculation needs clarification.
