Filtering Stocks by Price Range, Main-Flow Control, and Money Strength

Summary

This stock-screening note combines three conditions: price amplitude above a threshold, an indicator described as main-force control on the prior day, and ranking by capital strength. It gives a simple money-flow measure based on the difference between up-day and down-day price movement multiplied by trading volume, and sketches how to sort candidates by that measure. The intended approach is to favor stocks with activity and apparent buying pressure.

The note offers no backtest or measured results, and key terms such as main-force control and money strength are not defined with enough precision to ensure consistent implementation. It also cautions that the screen omits company fundamentals and may fail to adapt to changing markets. Suggested extensions include adding valuation, market context, other technical indicators, and longer-term trend or flow information. The code examples are illustrative and rely on data and calculations that would need validation before use.

Key ideas

• The screen filters stocks using price amplitude, a prior-day control indicator, and capital strength.
• Capital strength is illustrated through price movement weighted by trading volume.
• The resulting candidates are ranked from stronger to weaker capital-flow readings.
• The approach excludes fundamental information and may not respond to changing market conditions.
• The note recommends testing additional valuation, technical, and market-context filters.
