You can trade even if you do not have 10,000 Euro!

You can with margin trading! Margin trading is simply the term used for trading with borrowed capital. This is how you're able to open $10,000 or $100,000 positions with as little as $50 or $1,000. You can conduct relatively large transactions, very quickly and cheaply, with a small amount of initial capital.
Margin trading in the foreign exchange market is quantified in “lots”. We will be discussing these in depth in our next lesson. For now, just think of the term "lot" as the minimum amount of currency you have to buy. When you go to the grocery store and want to buy an egg, you can't just buy a single egg; they come in dozens or "lots" of 12. In Forex, it would be just as foolish to buy or sell 1 euro, so they usually come in "lots" of 10,000 (Mini) or 100,000 (Standard) depending on the type of account you have.

For Example:

• You believe that signals in the market are indicating that the British Pound will go up against the US dollar.
• You open one lot (100,000), buying with the British pound at 1% margin and wait for the exchange rate to climb. When you buy one lot (100,000) of GBP/USD at a price of 1.5000, you are buying 100,000 pounds, which is worth US$150,000 (100,000 units of GBP * 1.50 (exchange rate with USD)). If the margin requirement was 1%, then US$1500 would be set aside in your account to open up the trade (US$150,000 * 1%). You now control 100,000 pounds with US$1500. Your predictions come true and you decide to sell.
• You close the position at 1.5050. You earn 50 pips or about $500. (A pip is the smallest price movement available in a currency).

Your Actions	GBP	USD
You buy 100,000 pounds at the GBP/USD exchange rate of 1.5000	+100,000	-150,000
You blink for two seconds and the GBP/USD exchange rate rises to 1.5050 and you sell.	-100,000	+150,500**
You have earned a profit of $500.	0	+500

When you decide to close a position, the deposit that you originally made is returned to you and a calculation of your profits or losses is done. This profit or loss is then credited to your account.
We will also be discussing margin more in-depth in the next lesson, but hopefully you're able to get a basic idea of how margin works.
