Screening Stocks with Intraday MACD, Price Amplitude, and Afternoon Money Flows

Summary

This proposed stock screen selects for price amplitude above one, a shortening negative MACD histogram on a 15-minute chart, and net large-order inflows in the afternoon. The article interprets the amplitude condition as a way to find more volatile stocks, the contracting negative histogram as a possible sign of a change in price direction, and large-order flows as a possible clue to institutional activity. It provides sample indicator formulas and a Python sketch to combine the conditions.

The document cautions that the flow data can be affected by market conditions and that the screen may exclude some undervalued or promising stocks. It recommends adding fundamental, technical, macroeconomic, or industry analysis, and mentions historical data analysis as a possible enhancement. No backtest or performance evidence is supplied. The code sketch also leaves important data and implementation details unclear, including how afternoon flows are matched to the intraday signals, so the proposed rules should not be treated as a verified strategy.

Key ideas

• The screen combines price amplitude above one, a contracting negative 15-minute MACD histogram, and afternoon net large-order inflows.
• The proposed interpretation is that the conditions may identify volatile stocks whose downward momentum is easing alongside positive flow data.
• The article cautions that flow measures depend on market conditions and the screen can miss other opportunities.
• It suggests adding broader fundamental, technical, macroeconomic, or industry analysis.
• No backtest is reported, and the example code leaves data alignment and implementation details unresolved.
