Hi there, Can someone speak to me about the "significance" of preopen ask/bid prices? The concept is a little foreign to me. Nothing is actually being transacted, right? These ask/bids (currently 17:45 CST) are being advertised just for the heck of it? Are these ask/bids actually really meaningful in terms of telling me where the future is going to open at, or is it just "bluffing"?
