Green is Wednesday’s forecast; red is Wednesday’s actual trading data; and blue is Thursday’s forecast. The time is GMT +1, also known as the time in Western Europe or 6 hours ahead of Eastern Standard Time. In other words, the forecasts extend from 6:00 PM Wednesday to 5:59 PM Thursday Eastern Standard Time. We list the data based on military time. Thus, our graphs begin with 18:00 or 6:00 PM today and extend until 17:59 the next day.
