I do not remember exactly but it should be attached to the one chart only and it will trade on many pairs simultaniuosly. Open this EA in MetaEditor and read the coments (there are lists of pairs and brokers - just delete pair which you do not want to trade).
Also look on the TSD manuals
TSD Starters Pack
But probably you need this link:
Mindaugas - Metatrader 4 Version
It is description about settings, pairs and everything.
