I took a look at your site: Wow, that's a lot of concise information. I'm going to ask the simple question though...What are your selling? Advertising? In other words, you want more traffic into our site, like we all do, but is it like an online magazine? Do you make money off of referrals?
Here is a simple idea to garner more traffic. I am going to assume that you know quite a bit about the financial markets? You should set up a newsletter signup for whatever your specialty is or even a daily digest of financial news. Develop an opt in email list. You can place ads through email so this could be a revenue source.
Also, make sure you go into other financial sites and forums and join in the discussions and leave your site name. You can do this anonomyously (sp?) also.
You have lots of links going out, but when I checked your links coming in, you have very few. You need to have some of the sites that you promote, in turn promote your site. Your site has so much financial information, that I would suggest perhaps creating a financial newsworthy certificate that can be given to other financial sites if they so request, i.e. "This site certified as a "key financial resource" from
www.WallStreet.us, the key financial directory". Have little banners made and for the privlige of being assigned this certificate, make sure they place the certificate on their first or main page with a link back to your site. Target smaller finance or money advice sites. Make sure the sites receiving are quality sites.
This would be a start. Inward links are the key.
Hope this gives you some ideas.
