I'm having trouble with the new order window. I cant select symbol and type as well as the volume. I also cant select sell or buy. Here's an attached photo of the window. NB: I just opened a demo account.
Check the pairs that are availble for trading, you maybe have to add some in order to be able to "trade".
Go to: View >> Symbols of your MT platform and add those that are not greyed.
If the problem persists, try to open a new demo account with another server.
