it's easy, write good articles with enough of your targeted keywords, in this case the targeted keywords are the ones around forex trading.(check out google external keyword tool)
add a few keywords, and look which google spits out, then write your hub around those keywords.
submit your hub, and let technology do the work for you.
the 1st visitors you'll get are the hubbers themselfs, now when the search engine spiders notice your hub gets a lot of visitors, you'll get indexed, most hubs are indexed within a week or 2
also try to get back links on your hub, go to digg.com, stumble upon.com and other social bookmarking sites, add your hub to those sites and again you will get more traffic. to get higher traffic from google you need more back links.
Do you have a blog, place your hublinks, below a blog post, etc...
