Combining Intraday MACD, Weekly Trend, and Buying Activity for Stock Selection

Summary

The document proposes a Chinese stock screen that combines a reported daily buying-activity share above 5%, a weekly close crossing above its 30-week moving average, and a shortening MACD histogram on a 15-minute chart. The signals are intended to pair evidence of longer-term trend strength with a possible short-term turn upward and recent buying interest. Suggested additions include moving-average crossovers and valuation filters based on price-to-earnings and price-to-book ratios.

The author cautions that a short-term rebound may fail and that reported buying activity does not ensure favorable returns. No backtest, sample, or performance evidence is provided. The accompanying code appears inconsistent with the described rules: it references daily MACD data for a 15-minute signal, and its weekly trend calculation does not clearly implement the stated moving-average crossover. The screen should therefore be treated as a conceptual proposal whose definitions and implementation require verification.

Key ideas

• The proposed screen combines recent buying activity, a weekly moving-average crossover, and a 15-minute MACD histogram signal.
• The indicators are intended to align longer-term trend direction with a short-term reversal toward strength.
• The author suggests adding moving-average and valuation filters for further screening.
• The document warns that buying activity and short-term signals can fail, and it supplies no performance evidence.
• The code does not clearly match several stated indicator timeframes and conditions.
