I tried to ask this question a few days ago, but I guess because I inadvertanly mentioned the name of my broker my post got moved to the retail thread. I'm not interested in talking about brokers. In the old days, if you wanted to trade currencies you just put on a futures contract. Everything was defined, the time the margin, the amount. How do you trade forex? Is there a round lot? What is the margin? How do you enter an order? Thanks in advance for educating me.
