AAPL ascending triangle pattern

I read on investopedia that when prices reaches new highs on falling volume, watch out; a reversal might be taking shape. Also I read that ascending triangles can result in reversals approximately 25% of the time.

The other problem is that ascending triangles normally form over a period of a few weeks up to about 90 days. I would wait a few days after the price closes above the the trendline before longing longing stock.
