I read the Faqs but i did not understand how to do.
Thanks in advance.
Hi Kitano - Sorry it took me a while to get back to you. I don't think the process of creating a margin order and opening a position is any different when shorting on a EUR balance - the EUR balance will be used as "collateral" against the position just the same as it would for BTC. Did you try creating a margin order and run into a problem?
When you margin trade you are only "using" your currency balances as a kind of "collateral." So creating a margin order using EUR is the same as it is for creating a margin order using XBT. To margin trade you first select a level of leverage for your order (selecting a level of leverage is what makes the order a margin order instead of an ordinary order). If you want to create an order to short XBT/EUR, then you make it a sell order and specify the other parameters of the order (market order, limit order etc). If the order fills, you will have an open short position that must be closed with a leveraged buy order in the same volume amount. Again, this process is the same regardless of whether you have only EUR or only XBT balance in your account, because you aren't using your account balance directly to execute the orders. The execution of the orders is done with funds you are effectively borrowing against the value of certain currency balances on your account. Let me know if this doesn't answer your question fully.
