Nice to see a new trading platform. I have a suggestion. To get more users you need to make it popular. I mean you should make your site as a established brand among other trading platforms.
For that you need to promote your site via advertising networks like adwords, propeller ads or through signature campaigns. Second method will be more effective in my opinion. For example, one new exchange started a signature campaign and within few minutes, it became much more popular. Anyways we will try your trading platform to see the opportunities. All the best!
