Anybody seen any?

You can start by downloading a forex charting tool that allows users to create 
indicators and systems that can create trades to be entered automatically.

(a number of forex brokers use this tool as a interface for users to
enter and track trades[check www.fxstreet.com for more])
This is the main tool that most likely has the most systems for the
forex market, plus it's free.
 The company and brokers have joined to create a contest for the best
forex system...

 There is always plenty of talk in forums about trading systems.  Just
be sure to take it as their opinion and not fact.  What these people
are trying to build are automated systems that can make them money
while they do something else.  Some of the best traders in the world
do make millions a month based on a system, however, they manually
enter the trades.
 Careful and good luck.  I gave up on it and trade manual after I
found it to be a waste of time, no holy grail for me.
