No,  from 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

 

Maybe it is possible:

1. not in the standard strategy tester to do backtest, but ... 

some solution :

same expert but with additional / different calls for "OnlineSends" in case of test (simulate--trades) which will call :

 2. custom script or Exp.Adv. With

Instead of standard functions ( OrderSend, OrderClose, ...)  custom in "fileWriteRead" functions/tasks.

3. Probably -->  https://www.mql5.com/en/job  , (you know)

 

====

P.S. I had similar script/library but I had hdd-disk crash (bumped) with everything I had been writing in mql,

and now I'm ...busy working something else. (I hope idea helps)
