Volume, and confidence in an exchange.
I know Gox has had it's share of problems and coinbase doesn't treat some people fairly but BTC-E and Vircurex have gotten hacked and had people fucked over.

I still dont have answer to my question.I mean like can we buy for low price from one exchange and sell for high at another exchange?

Than again why would people buy from me for a high price when they can buy for low from the very exchange I bought.

It's called arbitrage trading. It's very likely there are people practicing it already.
