I'm new to trading in general, so please forgive me if this is a stupid question. I'm getting my feet wet with trying demo accounts. I made a 50 pound virtual profit on the bets I made, and the overview reflects it in my total. However, at the same time, it's saying I have a -323.50 loss with another bet. As far as I'm aware, I broke even on that position by closing it. It doesn't show up on my history, and doesn't show in my total. I'm approx. 50 quid up apparently, so, I'm confused as to why it's showing me seemingly conflicting information. My demo account also seems to have reset with no money, so I've no idea what's happened there. To be honest, I'm finding the UI incredibly unintuitive, but maybe I just need to get familiar with it.
