You cannot trust what you see until the market opens. Some market makers, ETMM, for one does not show their cards until after the market opens. What happens "Most of the time," is even if you make an offer for a higher amount you will buy at what ever is transpiring at the time. The limit order for buy means that is the top price you will pay. In all fairness to you, you should spend your money as you seem fit. Most experienced buyers wait until after the first hour of the day (Also known as amateur hour) before buying anything. GLTU
