It is not my first trade and I made losses on trades before, but this should not effect my current position i think 

I closed the possition now (but I missed to make a screenshot) and even when my realised profits where negative I made some profits because my unrealised profits was higher then my realised profits. It is still confusing because I dont now how to calculate it correctly.

Can I calculate my unrealised profits minus my realised profits to see how much the profit will be? How do you calculate it?

And why the realised profits turn in positive profits sometimes?

I read about it on Bitmex but its still confusing, I thing there should be a easy understandable way to figure that out 


Thank you for your answers!
