How does leverage work?
For sake of simplicity, say the Euro is trading at $1.25. You have leveraged control of $100,000 given the 100x leverage. If you are bullish on the Euro, you are long 80,000 euros. For every 1% it rises, you gain $1000. If it drops by the same 1%, you are wiped out, you lost your $1000. With the contracts I am familiar with, there is a minimum margin, and your account is "marked to market" each night. If your positive balance drops too low, you get the margin call. It's a zero sum game, for every dollar you make, there's a guy on the other side of the trade. Odds are he's doing this full time and is smarter than you.
