Methodology
We make a huge database with all the existing Forex Brokers in the world, gathering their website and social network: Facebook, Tweeter, LinkedIn, Instagram (when we could find it all)
Then we crawled the Number of followers for each social Network. With an algorithm we define a number of points by follower.
We also aggreged to our ranking the number of reviews and the rating on our website.
We will do an update every year and see which Brokers improv and the new comers.
