Hi again Adubasu,
In reviewing the GT-S manual, I see I made some mistakes in my previous comment to you. So let's take an example of my
hedge 
of GBP/CHF vs EUR/CHF:
Here are my settings:
Display Level 0
Unlock code (Use the code they gave you when you bought this robot)
Do Trades true
Block negative close true
Allow for
spread 
true

This is the
range 
bottom of GBP/CHF 1.5000 - top 2.5000 = 1.0000 /

50 = 200

.

Lots1 0.01 Here we set our lot size, instead of letting the robot calculate it.
Lots2 0.01 Lot size of EURCHF.
Magic number1 100001
Magic number2 200001 Do not change magic numbers, unless necessary.
It would be necessary if you ran this robot on another chart of GBP/CHF or EUR/CHF
Check for half
hedge 
true
Okay, that is it. Except I don't know whether or not a copy needs to be dropped on EUR/CHF as well. So I made another exact copy and dropped it on EUR/CHF.
Use the "Save" command on the robot's properties page to save a copy and the "Load" command to load it onto the second robot. Anyway this is what I am running. I don't have any results yet.
Good luck!
