There are some truths to these. Demo accounts do give newcomers a false sense of security in their abilities, since the emotional involvement with a pretend trade is nowhere near the emotional rollercoaster associated with a live trade with ones own hard earned money. And I do disclose this fact to all aspiring Forex traders prior to them going live. As far as the price feeds being different on demo accounts, this just isn’t true with the demo accounts we utilize. The exact same currency quote stream that feeds my demo also feeds my live accounts. They are both coming from the exact same ip address. I have heard of this problem on other demo accounts, but have no first hand experience with them.
