Can't trade 0.1 lots in MT4!? Help!

How can i adjust LOTS (Volume), because i can't trade but 1 lot, and i want 0,1 on my demo acc ?

It is not on the drop down list, but you can type it into the entry box and MT4 will remember it as the default for future trades. You have to type in 0.1, not 0,1.

thank you. It worked.
