How do I buy euros with euros

I don't understand logic here. If my account is in EUR an i want to go long EUR/USD how do i buy EUR when i already have euros?

You'll be selling US Dollars and buying Euros.

The amount of Euros you are able to purchase with your Euros will be much higher than what's in your account because your forex trading account is leveraged.

All right, you need to review some of the online materials on forex trading, currencies and the basics. And as others have pointed out, you would be selling USD and buying Euro. And in reverse when closing the trade.

emeraldeyes got it, and yes you should go through some basic forex trading courses (free ones) never pay for something you can get for free, try pipsology, its a really good start, just google it
