Automation on MarketWatch

I was reading the news on the financial markets and clicked on the news by MarketWatch. As I was reading the market update, I then suddenly realized that all the market performance inserted in between the words, is LIVE.

The above is just a screenshot to give you a flavour of what I’m talking about. But if you were to read it when the market’s opened, the figures actually changed automatically and instantaneously. You can read the whole news here. That is cool. But I wonder who or how does the text change if say for example the movements turn from negative to positive (i.e. from red to green), because the narrative has to change too. Is that automated too?
