Things can always turn for the worse at any time. I stand firm to believe no one actually has "boots on the ground" or knows anymore than what the news tells us. If I were a dealer, I would continue to sell my currency until the revaluation. the reval' could be tomorrow. It could be in ten minutes, it could be next year. No one knows an exact date and or time, other than the people pulling the strings in the background. From a dealer persepctive, you would want to keep selling your currency until the revaluation in order to keep money flowing in. Most dealers have a very large quantity of IQD, so selling some isn't going to make a big difference when the IQD reval's. Why stop selling IQD, when you can mkae two million USD selling IQD today, when you have no guarantee the rate will change tomorrow. Make as much money as you can now, in case something doesnt go the way you want.
It's the same concept as being a seller of Gold/Silver. Why would you sell gold/silver today, when the price can increase ten-fold tomorrow? It's because tomorrow is uncertain and you need to make money now in order to stay in business ad buy more stock.
