Stock Screening with Price Range, Main-Fund Control, and Shortening MACD Bars

Summary

This stock-selection rule combines three conditions: price amplitude above 1, evidence of main-fund control on the prior day, and shortening MACD histogram bars on a 15-minute chart. The document presents these as signs of activity, capital interest, and improving short-term momentum. It also gives a reference MACD calculation and an illustrative screening workflow, though the code is incomplete and mixes data and indicator conventions.

The article offers no backtest, performance data, or evidence that the conditions predict returns. It warns that the screen omits company fundamentals and may not adapt to changing market conditions. It suggests adding fundamental information, market context, other technical indicators, fund-flow measures, and longer-term trends. The terms “main-fund control” and the amplitude threshold are not operationally defined in detail, so implementation would require precise data definitions and validation before the rule could be evaluated.

Key ideas

• The screen requires amplitude above 1, prior-day main-fund control, and shortening MACD histogram bars on a 15-minute chart.
• The article frames these filters as measures of trading activity, capital participation, and short-term momentum.
• It provides an indicator formula and sample code, but the implementation is illustrative and has unresolved data and indicator details.
• The rule excludes fundamental analysis and may not adjust to changing market conditions.
• The document reports no test results, so predictive value and trading performance remain unestablished.
