2 different pairs

 
How do you program it to trade two different pairs while sharing the same account balance? Is there any way to do this?
 
Look at the parameters of OrderSend. The first one is symbol of the pair you want to trade. So you can send any order for any pair you want.
 
Whenever I try that it says "Unknown symbol name "USDCHF" for OrderSend function

If I attach the EA to the USDCHF chart then that one works but then all the other pairs are unknown. Is there another command to load another pair into history?
 
USDCHF must be peviously added in the MarketWatch window
 
I added it and it still won't let me open a position on a different pair. Is this something the Strategy tester cannot do?
 
Nevermind, I found the answer here: 'Testing Features and Limits in MetaTrader 4'

"Trading is permitted for the symbol under test only, no portfolio testing.

Attempts to trade using another symbol will return error"
