Why not contact them directly? I've never understood why people prefer to post on a message board rather than pick up the phone or send an email. It's their job to help you...
I don't care, but he's asked twice in two days. If he had asked for a review of the firm, then I would understand the need to utilize a message board. But, I think practicalities are best answered directly by the firm. For the record, I know of a Norwegian trader that was using ECHOtrade several years ago. However, I can only see "State" (as opposed to country) in their contact form now: http://www.echotradeonline.com/contact_us.php
Dont do it. If I am not wrong , you need series 7 and am paid on a K-1 at Echo, this means that your income is effectively connected and you will have to file taxes in the USA. a W8-BEN form will not cover this
A direct quote from a trader's post on another thread, regarding Echo's LinkedIn profile: "You must be a US or BC Canada resident with an active Series 7 to trade with us."
