I'd like to pose a wager in response to this thread on theta as an edge: http://www.elitetrader.com/vb/showthread.php?s=&threadid=206870 I'll bet anyone on here that I can propose a listed trade (US exchanges), in advance, that will produce at least a 20% gain by the close of trading on 9/24/2010. The trade will be based upon the worst-case inter-exchange pricing at 2:30pm EDT today; and the offset at the worst inter-exchange pricing at 4:00pm EDT on the 24th. I will send the screenshot via email to a new gmail box today, so it will have today's time stamp on it. I will post the email address and password here after 6:00pm EDT on the 24th, provided the bettors have seen it first. Anyone can wager (cash) against the proposed gain. Simply drop me a PM or post it here. $100 against hitting 20% gain and only from aliases I know. So the question, is this an edge?
