Re: relative to
I"m not sure the second conveys the idea you want to convey.
The first, as J&K has said, is not a sentence. It's a noun phrase. Your sentence is correct grammatically, but it's not saying anything. Everything can be relative to anything.
As another example, let's say I had a fragment that said "The dog running." You could say "The dog is running" but what did you want to say about the running dog? The dog running through the yard just saved my life? The dog running to greet me is the best dog in the world?
Someone must have wanted to say something about the two trade values, but what?
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
