does anyone know the official forex holiday hours for christmas/new years here in the states? it seems like each broker is a bit different from the next, but nothing official. i'm using MBTrading with Quotetracker, and have several diagonal trendlines i use, and am concerned about the holidays screwing them up by adding/removing time that it should not. so i would like to know what the official hours are so that i could make adjustments if necessary. thanks!
