That "bias"

has been covered in depth here:

As mentioned, I started PipCop because I wanted to find a robot that worked. Due to my expertise at web sites, I figured I would share the results. The Forex Goldmine family of products were the few that I found that worked, and Jerry approached me to sell them as one of his three authorized resellers and I accepted his
offer 
. I was selling the products from PipCop.com but decided to make their own site, hence the email.
As always, it's a buyer beware world out there, but I will say I am sold on the FG products. They work, they don't freak me out, and that works for me. However, you can review all the other data and make your own decisions. I wouldn't entirely rely on anyone else telling me what to buy, and I hope you wouldn't either.
Anyway, I am putting together a feature comparison, but here is the basic breakdown:
RoboMiner II:
3 settings, basic, easy to use
RoboMiner Pro:
More settings, can trade on any
currency 
, has stealth mode to hide
TP 
from brokers, and can be tweaked to double profits.
GT-Shadow:
A ton more features, some that are so advanced I have a hard time understanding. Can
hedge 
across two different currencies.
Prospector:
Uses Fibonacci sequences to open trades, only opens one trade at a time. I just started a demo account on this so I will try to get a statement up for you.
My take is that I would pick up the RM II first, or maybe the RM Pro and get both at once.
