No verifiable information is given about the company. It's $150 per month, and I don't see any hint of a trial period or refund option if the signals fail.
The site has Copyright © 2007 at the bottom, unverifiable signals records go back to January 2010, but the website was registered on July 12, 2010.
Why am I suspicious that Medvedev owns 4usignals?
Overall, I'd recommend passing on this one until a lot more info becomes available.
