The currency market has no building, no opening bell and no single timetable. It works as a chain of financial centres passing the baton: when one closes, another is already trading. The result is a market open continuously from Sunday evening to Friday afternoon, according to the platform’s server time.
The chain begins in Oceania and Asia. Sydney opens the week on modest volume and Tokyo takes over shortly afterwards, with the yen in the lead and a strong influence from Japanese, Chinese and Australian data. It is a session of tighter ranges, in which many pairs build the reference level that Europe will break or respect hours later.
London is the highest-volume session of the day. Europe accounts for the largest share of global currency business and, when it opens, liquidity multiplies: spreads tighten, the big institutional flows appear, and the euro and the pound move to the front. Many breaks of the Asian range happen in the first European hour.
New York joins when London is already halfway through its day. That overlap, roughly between 13:00 and 16:00 GMT with variations for daylight saving, is the deepest window of the day: the world’s two largest centres coincide and, on top of that, most US macroeconomic releases land inside it.
Once London closes, the market thins out. The American afternoon usually brings wider spreads, less depth and moves that run out of steam early or, conversely, abrupt legs caused by orders that would barely register during high-volume hours. Trading with the same aggression at two different times of day does not carry the same cost.
Friday’s close and Sunday’s reopening deserve a paragraph of their own. The market stops quoting, but the world does not: elections, policy decisions, geopolitical tension. When trading resumes, the price may do so far from the last close, leaving a gap with no prices in between. Holding positions over the weekend means accepting that risk.
Hence a practical conclusion: the session should be chosen before the strategy. Scalpers need the hours of maximum liquidity, because the spread weighs on every trade; swing traders can enter more calmly, though they are well advised to avoid moments of thin depth. And there is one factor no manual mentions: the trader’s real-life schedule. In MetaTrader 5 you can check the server time and each instrument’s quoting sessions before designing a routine you can actually sustain. Trading currencies carries a risk of loss.
