As far as i am considered, that the silver is a very important part of the forex business. It is mostly used in conjunction with the gold. But, it may be used all alone as well.
Just like the other items of the forex business. It also behaves like them in them same manner. But, there are some problems with the silver these days. This may not be the case all around. But, these days it is facing some of the short comings which will definately be over come in the near fututre. But, as far as it is concerned at the moment it is at the down fall.
