O'Reilly chart

O''Reilly Automotive is currently forming an ascending triangle pattern, a bullish continuation setup that signals upside in shares. The pattern is formed by horizontal resistance above shares -- at $255 in this case -- and uptrending support to the downside. Basically, as O'Reilly has been setting up this price setup, shares have been bouncing between those two levels, getting squeezed closer and closer to a breakout above $255 in the process. When our $255 price ceiling gets taken out, we've got our buy signal. Source:thestreet.com/story/13313037/2/5-breakout-trades-to-buy-now.html
