BlackBull Markets MetaTrader 4 Server time is based on the industry standard, “5 pm New York”. This time is internationally recognised as the day's end in the Forex markets.
As the United States has daylight savings time and the MetaTrader 4 Server Time does not, this means there will be a change of market open and close times twice a year. In March of every year, the U.S. turns their clocks 1 hour forward, this can result in an earlier market opening. In November, they do the opposite and turn their clock's backwards 1 hour, this can result in a later market closing.
Depending on your time this may not affect you at all. However, if your time zone is affected by the change, you can visit our Company News page for announcements about daylight savings time changes and the specific dates for that year.
The only noticeable change that you will experience is that the Market Watch time in MetaTrader 4 will change to GMT+3 in March and GMT+2 in November.
