Sunday EUR/USD tracks a perpetual contract referencing US dollars per euro. It can move during the regular FX market’s weekend closure. This is a cash-settled derivative, not an exchange of the currencies; it has no expiry and uses funding payments to align the contract with its reference. The chart shows the latest 24 hours. PREV follows the same reference logic as regular EUR/USD, using its latest closing value while regular FX is closed. Compare the two charts to see weekend price differences.
Comparing charts on this board
Pair this chart with regular EUR/USD to compare weekday FX with the weekend perpetual market. During the regular market’s closure, its latest closing value provides the comparison reference for judging how weekend news changes the balance between the two currencies.
Compare it with Sunday USD/JPY. Falling EUR/USD alongside rising USD/JPY points to shared dollar strength; the opposite combination points to dollar weakness. Because the dollar sits on opposite sides of these pairs, reverse the percentage-change sign when comparing its direction.
