No settlement, daytrade as much as you want on margin with no limits in an extremely liquid market, no wonder people are addicted to Forex.
I'm been playing with a demo account all night and I have to say one of the biggest plusses to me has to be how easy it is to get in and out of a position versus stocks,.
Pay taxes anyway, it's the right thing to do even if the Forex tax laws are discombobulated and the IRS won't tell you for certian which tax laws you should go by. But Doodi digress.
