Any plans to make margin trading finally a bit useful at cex ?
I mean currently you can only close the whole position at once (1) and only at market price (2). This is absolutely horrible and every sane exchange would forbid every user to do such a rubbish Cheesy So margin trading is in fact just dangerous and not any benefit to anyone yet.

yeah I agree, those two things are pretty annoying.

Also I am having trouble understanding how the profit/loss from margin trading is calculated. Maybe somebody here can help me, I just closed a small position:

Code:
Position # Open date      Close dat     Type   Leverage Amount      Margin      Open price Close price     Stop loss Fee P/L
         32323  2017-11-02 17:03:54 2017-11-02 20:08:57 Short 3 855.48 EUR  285.16 EUR     6110.5710 6074.6781    8512.2647 0.58 2.77 EUR

it was a 3:1 margin position, 0.14BTC short.

When I calculate this the profit is: (6110.571-6074.6781)*0.14 - 0.58 = 4.45

Then WHYYYY does it say profit: 2.77

I think I am going cazy.....

This is a bug with CEX.IOs margin trading facility. The amount of the resulting trading position is not only wrong, it even depends on the leverage you choose. For example, if you open a short position of 3 ETH with leverage 3, then only 2 ETH are sold; with leverage 2, it would be only 1.5 ETH.
I reported this bug on 7th of April to CEX.IO. However, the support was incompetent and insisted that this is desired behaviour. Since CEX.IO's margin trading facility isn't usable anyway, I didn't bother to educate them and let it go.
