NUAN Sold Long position at $18.30, didn't like the descending triangle

After some volatile days, I didn't like the look of the descending triangle developing in NUAN, so closed out this position flat. Can always get back in if it takes off again. It looked like it was tracking nicely between the channel marked in red, but the last 10 days had five red candles, and MACD and RSI both showing down trends.
