Hey Samuel,
It is not a shame for EA Studio but MetaTrader. The developer, Mr. Popov, is so good that he can do everything.
BUT MetaTrader does not allow it. You can not trade different assets on one chart in MetaTrader.
This is why he is now preparing different products for different platforms like Trading View.
MetaTrader is the best so far, but there are many limitations, so the EA Studio has to follow along.
