Hi Doug,
I looked over the site you suggested and here are my thoughts. First, I am a perpetual skeptic of claims whenver the promoter does not post the trade logs of each robot. They do post summary information but I could not find anywhere on the site where they post trade logs for each robot. Each link takes you to a commercial site where they hawk their wares. There are too many things there which just smack of suspicion.
If you are inclined to spend the money for a robot, what guarantee does the company give you if you are not satisfied? If it is 30 days money back guarantee with no questions asked, it might give you enough time to test it yourself but realistically you need to be able to generate enough trades (live trades) to have statistically viable results (minimum of 100 trades).
Do a google search on some of the robots listed to see what reviews you can find and look in the forums for people who are experienced with them. Get their feedback before taking the step of purchasing one. Remember, become your own expert. You will have less chance of being a victim.
Hope this helps you.
