Hello,
i do not know if this is even considered a problem, but anyway i have been searching for an answer and not finding it.
I have a Demo Accounts and Today tried Dukascopy MT4 Demo, had very low spreads and great for scalping except before the end of the day by an hour the Demo withdrawed 20% of the Account, is this the Comission Fee ? because to be honest no one writes his comission fee on the website 
Thank you 
Roll charge?
Roll charges would happen if i had open Positions, but i did not
The money in your demo account cannot be withdrawn, unless it is a demo contest. I have participated in a couple of demo contests, though I didn’t emerge as the winner, but I enjoyed it well, and it helped me sharpen up my trading strategy.
Demo account is not a real account we use it for trading practice. profit made on demo is not with drawable. There is huge balance in thousands in demo its easy to make profit on it . Demo account is not your own account to make transactions. Value of demo is much for beginners to gain practice freely.
That’s really [U]very[/U] strange; you need to ask Dukascopy’s support staff what’s going on, there. People here can only [I]guess[/I], and that’s probably not really going to help you?
All of that is completely true, but it doesn’t even begin to answer the OP’s question. :58:
