I would also like to know this, but I don't think they would volunteer this info and hand over a trading advantage to their clients.
This is an interesting question. I also faced this question myself. It not clear form the site where the price information come from.
Mr. Exxe,
I have been trading on your site for a month, I majorly trade the forex. My question is from where does you site pickup the price of different currency pairs it is definitely not from metatrader...just wanted to know so that I could improve on my trading...
