All indices threw a gap, NDX now has a gap underneath and a gap above. "By law" both gaps have to close. Unlike index gaps, future gaps almost always close, and since we're at the gap, I expect both of them to close within the next couple of weeks.
Get ready for some huge whipsaw action. Not sure which one it closes first, but I would have to assume it goes up and crashes.
The alternative scenarios is that it closes the gap below overnight then goes pumptarded tomorrow. In any case, watch the gaps.
