3 pair backtest in MT4

Hello. I coded EA that trades one currency pair BUT it trades only if there are suitable conditions on 2 other pairs.
My question is:

Can this be backtested in MT4? Can the MT4 read data from more currency pairs? These pairs are hard coded, and backtest runs only on 1 pair

no

you need to do so in mt5

save all backtest
after
search by google
ReportManager v1.3.0 and download

you can see all backtest same time

for fix lot system its this ok
