Combining 15-Minute MACD Contraction with Large-Order Flow and Range

Summary

This Chinese equity screen combines three short-term conditions: price amplitude above 1, a high ranking for net large-order volume, and a shrinking negative MACD histogram on a 15-minute chart. The intended interpretation is that active trading and easing downside momentum may help identify stocks for short-term or swing trading. The document gives indicator formula examples and suggests sorting candidates by trading value.

The author cautions that the approach relies heavily on technical signals, can miss company fundamentals and broader market changes, and uses a lagging MACD measure whose timing may be imprecise. Suggested refinements include adding fundamental, industry, and market-trend analysis, tuning MACD settings to the trading horizon, and applying stop-loss and take-profit rules. The sample code is illustrative rather than convincing empirical support: it does not demonstrate results, and its daily-data example does not establish that the 15-minute condition is correctly implemented. No backtest, benchmark, or risk-adjusted performance is reported.

Key ideas

• The screen looks for amplitude above 1, a strong net large-order volume ranking, and a shrinking negative 15-minute MACD histogram.
• The signals are presented as a short-term way to combine trading activity with weakening downside momentum.
• The author recommends adding fundamental, sector, and market context and managing exits with stop-loss and take-profit rules.
• MACD lag and dependence on technical factors are identified as limitations.
• The examples provide no performance evidence and do not clearly validate the stated intraday signal.
