Got the reversal- How long are the legs?

The McClellan Oscillator remains in bullish territory, We are seening a stall here at the upper trendline, a break above the line will be accompanied by a sharp move in price. Of course, the possibility exists for a minor pullback here, but upward momentum is very strong and pullbacks shoould be met with buying.
