|Month Average for all time zones
How are the monthly averages calculated?
Month Average is the average of the prices in each column.
Month Average for all time zones is calculated as follows:
- The sum of the daily prices is divided by the number of prices set during that day to give a daily average.
Please note that in times of high volatility more than five prices may be set during a one day period and this average will include interim prices as well as those listed.
- The daily averages are added together and divided by the number of days on which prices were set during the month.
