You need a creative strategy to make money in 2011...
This virtually always implies building custom software systems.
At the very least...
You will have to get a high-end solution with a 1st class data warehouse...
You're talking 5 figures/month...
And then add extensive custom features via their API.
There are NO successful trading firms running off-the-shelf software...
This is a myth believed by people with $10K accounts.
