Different BTC exchanges connection?

[trex]

Is D and S from different BTC exchanges connected?

Thank you for explanations.

I Googled it.

It is not connected, prices are different because of different fees. Buying at one and selling at other exchange is called arbitrage, but difference has to be big enough to make profit. Also withdrawal at Mt.gox takes long time.

Home it helps anyone.
