after reading that article about prop shops and trading arcades and seeing that reference to trader dna i did some research and found this web site:
http://www.traderdna.com/

but it doesn't tell you much about the software that they sell. has anybody tried their software or know anything about it or can tell us more about it?

I sent an email to [email protected] (which is on their contact page) inviting them to tell us about their software.
