Now the unwanted transaction is recorded in my HISTORY screen, my balance shows the corresponding BTC amount prematurely bought and just a couple of cents in EUR. Fair enough, I might have made an error, even if it did not look so. But now, in the TRANSACTION screen, I can ALSO see my limit order correctly opened and waiting to be executed. The OPEN ORDERS screen does not show the limit order, so I do not have an option to Cancel the limit order.
Now I wonder: what will happen if the limit order is triggered at €5823 while my EUR account is practically empty?
Should I open a ticket there?
