I don't use stops trading from the long side at these levels in the SP 500, that being 900. As long as I don't leverage myself into a position were I would get a margin call, it always comes back. The index willl never go to zero like stocks can. I would never trade like this with the SP500 above 1100. Thats based on my account size. Sure I may get trapped lower and have to wait out the rise, but it always comes down at these levels.
