Transactions View: Understanding Margin Trading Transactions

Anyone know how to understand Margin Trading Transactions?

In the transactions listing it shows the following:

  • 0.1234567 Eth
    = £figure / £figure Cost Basis.
    +figure GAIN (in green) / Margin Trading Loss.

I can’t understand why it shows a figure in fiat, a cost basis & a gain (which is the fiat figure minus the cost basis) but yet is says a margin trading loss and a minus sign before the eth. Makes no sense at all.

Does anyone understand any of this & can someone please explain what i’m looking at?
