Stock Screening with Intraday MACD Histogram Contraction and New Lows

Summary

This Chinese-language post proposes screening stocks for amplitude above 1, a shrinking negative MACD histogram on a 15-minute chart, and a current low below the previous day’s low. It interprets the range condition as selecting more volatile shares and the contracting MACD histogram as a possible sign of changing momentum. Example formula fragments and Python code illustrate how to combine daily price data with intraday MACD readings.

The post gives no backtest results or evidence that these conditions identify a reversal. It warns that a new low may reflect negative news and that high-amplitude stocks carry greater risk. It suggests adding indicators such as KDJ or OBV and considering market conditions, trading hours, price-change limits, and turnover. The code checks whether qualifying conditions occurred anywhere in the retrieved data rather than clearly requiring them to coincide in the latest observation, so its implementation may not match the intended current-day screen. The method is therefore a screening idea, not a validated entry strategy.

Key ideas

• The proposed screen combines price amplitude, a contracting negative MACD histogram, and a lower daily low.
• The MACD condition is evaluated on 15-minute data, while the low comparison uses daily prices.
• The author notes that a new low may precede further declines and that high amplitude increases risk.
• Suggested refinements include additional indicators and market or turnover filters.
• The sample code may accept signals from different historical bars instead of requiring them to coincide.
