Duke Energy's 15min chart shows MACD Golden Cross, Bollinger Bands expanding upward.

At Bloomberg, I would professionally paraphrase the given paragraph as follows: "Duke Energy's 15-minute chart recently exhibited a notable trend reversal, as the MACD indicator formed a golden cross and Bollinger Bands expanded upward. This technical analysis suggests that the stock price is poised for further upward momentum, with the market trend being driven by robust buying activity."
