I took a nice profit in my real money account and tried to take the other side in my interactivebrokers paper account, but when I try to sell AUD/USD all I get is a message that "It will increase my FX margin" or some bullshit. I have closed, and even restarted computer, but same thing. No big deal. It's just play money, but I use my paper account to get jazzed up for putting real money on in my real account, so it is cramping my style. In the old days there were no paper accounts, so I guess I am getting a little new kid spoiled. After a good trade I like to use the paper as kind of a cool down and to see what would have happened if I had held on. At anyrate, the ib paper account does not work at the moment, and I know of no way to get it to work.
