Stock Screening with Moving Average Crossovers and Auction Net Buying

Summary

This article describes a stock selection rule combining three conditions: amplitude above a stated threshold, a bullish alignment or crossover among three moving averages, and positive net buying attributed to major participants during the opening auction. It frames the auction flow filter as an addition to technical signals that may reflect trading activity and buying pressure. It also provides a rough indicator and code example, though the written rule and sample implementation do not fully align in how they express the moving average condition.

The article warns that reliance on technical signals and short-term trends can make selections unreliable after major market changes, and that auction net-buy data may arrive with delays that distort timing. It suggests adding fundamental and industry criteria, comparing auction flow across periods, and evaluating variants with historical backtests. No backtest findings, parameter definitions, or evidence of profitability are supplied, so the screen is best treated as a proposal requiring data validation and careful implementation.

Key ideas

• The screen combines price amplitude, moving average signals, and positive opening auction net buying.
• The article presents auction flow as a filter for activity and buying pressure.
• It notes that changing market conditions can weaken a short-term technical screen.
• Delayed auction flow data may cause mistimed selection decisions.
• Fundamental and industry filters and historical evaluation are suggested, but no results are reported.
