running 3 pairs on the same chart and same EA..!!!

[bacharchoura1]

how can i run an EA on ONE chart (for examble eurusd) but it must open trades on 3 pairs simultinuosly ( for examble eurusd, eurpjpy, eurusd).
the reason of this is to succeed to make the optimization for the EA when in runs on 3 pairs together on the same account so we can choose the best pairs with the right corralition between them ???

hope you can help with this..

Tee off your last block before buy/sell, use 3 separate, buy/sell blocks with a different symbol in each 1
