Opening of the Trading Week

There is no officially designated starting time to the trading day or week, but for all intents the market action kicks off when Wellington, New Zealand, the first financial center west of the international dateline, opens on Monday morning local time. Depending on whether daylight saving time is in effect in your own time zone, it roughly corresponds to early Sunday afternoon in North America, Sunday evening in Europe, and very early Monday morning in Asia.

The Sunday open represents the starting point where currency markets resume trading after the Friday close of trading in North America (5 p.m. Eastern time). This is the first chance for the forex market to react to news and events that may have happened over the weekend. Prices may have closed New York trading at one level, but depending on the circumstances, they may start trading at different levels at the Sunday open.
