Sometimes it is not just TA but the intuitive sense. A 300 Dow points drop day would imply a trend change or sentiment change in direction. It normally continues for a few days and if anybody (I think NM) still thinks a gap up, one should have his head examined....nothing against NM. If one really believes that there will be a gap up for "da boyz" have to cover naked calls, he or she has no business in the market.
