One more leg to the upside? [Very short-term analysis]

Look like NEO is forming ascending triangle on the 30 minutes chart and it's usually bullish in upwards trending markets. The volume is declining, that means probably a breakout is coming. The target calculated by taking the height of the triangle, at its thickest point, and adding that to the breakout point. So the target is 21$. This target meets with previous resistance from the past.
If it's breaking to the downside I'm watching 16.50$-16.90$ area for weak support, it lines up almost with 0.618 Fibonacci level (16.50$).
