S&P 500 futures are up 39 points, or 0.85%, just ahead of the open.

That should be enough to get the market through the February double top, which is at 4595. If we get a clear break and a close above, there isn't much standing in the way of a return to all-time highs. What worries me is that today's war optimism could disappear as quickly as it arrived.
