how often do brokers change which markets they offer and what happens if you have a position open on a position when they decide to stop offering it for trade. i was looking at the us dollar yesterday and now the day of the non farm payrolls annoucment they dont have it as a market to trade and only have the futures of the us dollar - march and june. doesnt seem right? am i missing something? i think i also noticed rolling coffe taken off a few weeks ago and replaced with coffe march and june or something similar aswell.
