I am seriously suspicious of this site and this service, simply because of how old it looks. I mean seriously, html from the 1990's is the primary reason for me not to take any website or service seriously.
I took several trials of the Nostradamus signal service and found it to be total crap. It simply is a overbought/oversold indicator marketed as being based on some Neural Network. The predictions of where the market price will be in x-minutes done by the program is worthless. Maybe 1 in 20 it will even come close. Save your time and money!
