Stock Screen Using Price Range, Recent Control Proxy, and Annual Gain

Summary

The article describes a stock screen combining daily price amplitude above one, a condition labeled as prior-day main-force control, and a gain exceeding ten percent over 2021. It presents amplitude as a measure of trading fluctuation, the control condition as a proxy for capital flow, and the annual gain as evidence of an existing upward move. The article suggests adding company financials and industry prospects to complement these price-based filters.

The post gives indicator references and sample code, but no backtest, performance statistics, or evidence that the selected stocks continued rising. It acknowledges that changing market conditions can make the screen ineffective and that excluding fundamentals may lead to poor selections. The described control proxy and example implementation are not fully explained, so their definitions and date handling would need verification before practical use.

Key ideas

• The screen combines price amplitude, a prior-day control proxy, and a 2021 gain threshold.
• The article interprets the filters as volatility, capital-flow, and trend clues.
• It recommends considering financial condition and industry outlook alongside technical filters.
• No backtest or evidence of future performance is supplied.
• Market regime changes and unclear implementation details limit the strategy’s reliability.
