Why is the buy price different from the sell price of a stock? [duplicate]
This is called the Ask-Bid Spread. The difference varies based on the liquidly of the asset. The more liquid or the higher the volume of trades for the asset then the smaller the spread is. The spread goes to the broker to pay for some of the cost of the trade. My guess is that when there is a higher volume of shares being traded, brokers need to take less of a fee per share out of the transaction to cover their costs. This makes the spread is smaller.  This is essentially the difference in   price between the highest price that a   buyer is willing to pay for an asset   and the lowest price for which a   seller is willing to sell it. The seller will get the bid price and the buyer will pay the ask and the broker keeps the spread. From http://www.investopedia.com/terms/b/bid-askspread.asp
