Eur/Usd - Price feed is frozen

MK, Every Sunday when the Eur/Usd Forex opens at 5:30 p.m. EST, the price feed on C2 remains stuck at the opening price during the Sydney session from 5:30 EST and does not change until the Tokyo open at 7:00 p.m. EST? FXCM and Bulldog FX has the correct price movements on their website. Not sure why the price doesn’t move on C2 for the first hour and a half?
