Umm. Here I would like to explain.
In Pre-Market, the orders are just accepted from 9.00AM to 9.07AM. The orders wont be executed. The order execution will actually start at 9.08AM. So in between, you can place order in any range, and hence, buyers place order way above yesterdays closing and sellers place orders way below previous close. I don't know why they do it, but they do. There are very few times when such order gets executed. So this is when you see some orders at very different prices. But these trades happen rarely.
I hope it clears something.
