say 1000 contracts short on EUR-USD, what will happen to the market? given the huge leverage in FOrex, it is not entirely impossible. what if I unload it during quiet hours say after 4pm when there is not much volume. It will be an interesting experiment because if the market does not move at all, then we can say supply-demand has nothing to with price. because if it does move the market, then everyone in the world and their grandma will gather money together, say 500k dollars, put it in META4, and short or buy huge contract between quiet hours and make a killing. maybe i missed something here.
