Are you form USA?
Thanks so much. I visited both the Cortal and Comdirect sites but find both rather incomplete, especially lacking a clear list of tradable products and available exchanges. I requested a Cortal info-pack by email but apparently there’s no immediate delivery.I come from Germany - Discount Brokerage Companies like DAB bank, CortalConsors, Comdirect offers Clients Cross Border Trading and as long as you are not an US resident (or from a blacklisted country) you'll be welcome there. Website and Trading tools are good enough to place orders on international exchanges.
If you wish i can do more research.
