Intraday Stock Screening with Activity and a 15-Minute MACD Signal

Summary

This Chinese stock-screening post combines four conditions: amplitude above 1, current trading volume above 10,000 lots, an open above the previous close, and a 15-minute MACD histogram described as shortening while negative. It presents these as signs of active trading, positive opening sentiment, and a possible easing of downward momentum. The post includes a formula reference and a Python sketch, but their implementations do not consistently express every stated condition, so they should not be treated as validated equivalents.

The author flags noisy or uncertain signals, overfitting, and MACD lag, and suggests comparing with other indicators such as RSI or KDJ and considering fundamental measures. No backtest results or performance evidence are provided. The screen is therefore a heuristic for candidate selection, not evidence of profitability; the post gives no exit rules, position sizing, or detailed risk controls.

Key ideas

• The screen combines amplitude, current volume, a gap up, and a 15-minute MACD condition.
• The post interprets a shrinking negative MACD histogram as a possible reduction in bearish momentum.
• The formula and Python example may not faithfully implement all the stated conditions.
• The author notes noise, overfitting, and lagging signals as risks, with no performance results supplied.
