Thanks @chantal. I wish I’d taken a screengrab of the purchase screen because I’m so sure that it said I was buying at that lower rate. But lessons learned
The price shown is just the best ask at that specific moment you won’t get exactly that unless you did a limit order to set the max you would pay per share.
It’s particular unlucky as the German exchange has major technical issues this morning.
Also you are fully aware you are essentially taking a short position and it’s twice the leverage as in you really really want it to go down.
