Does a forex price guarator exist ?

hi everybody,

Does a forex price guarator exist ?

i mean, some 'insitution' which is over the parts, and has historical and spot real prices ?

I wonder which is the right price, as every broker has his own prices...

Thanks

e-Signal or something is independent price quotes provider I believe. Try it:

There is no one "right" price for a given pair. It's all about consensus between all the banks/traders based on what price produces an equilibrium between buyers and sellers.

The prices should be very close between all the banks out there however. If they weren't, it opens up the possibility for arbitrage which would drive the prices back in line.
