If we break 1630, then could be a melt up.
Before computers, i would wait for a big up day to start shorting the market off this kind of pattern.
Will seriously consider shorting late friday if we do go up more than 2%.
Then again, 1630 could be all she wrote, typical that markets will do what makes the most people lose money, so the few can get more and more and more.
BTW, you could look at current pattern as a bullish flag formation, upside target 1800.
