We are looking at setting up a new ?interest? website dedicated,
primarily, for financial trading through the use of spread trading
brokers but also providing coverage on sports betting and gambling.

We are targeting beginner to intermediate traders in the UK. The site
will be free to access and generate revenue initially through
marketing initially.

Right so my initial questions are?

1. Based on what we are planning who are our competitors for traffic
(remember just UK sites).
2. What key features do they offer?
3. How much traffic do they get? I understand this will depend on
stats exposed in the public domain and may not be available for all of
sites.
4. How do they generate revenue.
5. Any other relevant pieces of information. 

Prefer ?over-information? at this stage ? and happy to pay a good tip
for good insightful answers.
