Market Order-- to sell Hutchison: sell Hutchison now at whatever prevailing market price. Usually one will get the stock at the ask price of the moment when the order reaches the exchange. Sometimes, one gets a series of partial trades (partially filled orders) at different prices, the shares of which add up to 2000.
You will notice that the bid price and the ask price are never the same. The ask price is always a little higher than the bid price. What this means is if you are buying the stock you pay the ask price (the higher price) and if you are selling the stock you receive the bid price (the lower price).
