Erik, I may be a little ignorant, but when you look at the level II quotes, how is it possible for someone to put in a sell order at $16.88 and $25.00. How is this done because if I put up a sell order (lets say at $10), my brokerage firm "TDWaterhouse" won't let me.....and they won't even let me put in a sell order for more than a month from now! Thanks.
