Thanks for this useful list

I think I noticed a small error
You put Alpari (UK) and the url for the Alpari Russia.
The site for Alpari UK is www.alpari.co.uk and the one you have is for Alpari russia. They are 2 different companies.

On the useful information you could add later may be in which currency accounts can be open.

Maybe to help you for some of the brokers you can check in www.brokersmatrix.com
