Good luck getting this trade on at 2076, though. The futures start trading in an hour or so, and going by where everything else is opening up, I'd bet the futures open up 10-15 handles lower (implying an index level somewhere around 2060-2065).
So you might end up being 100% right, purely because Greece voted OXI and now everyone's going to start panicking, but you won't be able to do anything about it. If you didn't already have this trade on on Friday afternoon, you won't be able to get it on before it trades through your t/p level.
Update: yeah, the futures are being indicated at 2054; cash-futures basis is about -8 points; so that puts the implied index level about 2062.
Also, if you don't mind me being a bit rude: this is one of those situations where TA is pretty much useless. You're basically just betting on the opening gap in the SPX on Monday morning, and that's completely dependent on the outcome of the Greek referendum.
Update 2: first print in the futures was 2038. Hope you had this one on before the market closed on Friday.
