The gap back on May 3, between 1598 and 1617, will be filled before this small correction is over is my best guess.
so 1595 to 1620 is my target for the move, and if 1620 holds, then a new high is likely. If we drop to 1595, them the next rally will fail, although a new high in qqq without one in spx confirms the top is in.
BTW, in april 1987 the spx had a formation like this, after a massive straight up move from Sept 86, and that correction lasted into mid may, followed by another big more up. anything is possible, nothing is certian.
