News can cause two reactions:
News impulse. The market receives new information suddenly or unexpectedly. In most cases, it’s a strong mismatch between consensus forecasts and the actual values of published economic data.
News trend. New information has a smoother and more stable effect on the change in quotes. Such trends mainly appear after new “input” from politicians during speeches/press conferences. In some cases, important economic data also causes trends after the impulse reaction has finished.
