Currently, I see three stocks with increased buying pressure that are presenting great trading opportunities.

The pattern these three stocks are all in is called an ascending triangle.

In technical analysis, triangles appear to reflect a balance of forces, causing a sideways movement in the stock that is usually associated with decreasing volume and volatility.

The ascending triangle (also called an ascending right triangle) is a bullish indicator. It is characterized by a rally to a new high, followed by a pullback to an intermediate support level, then a second rally to test the first peak, followed by a second decline to a level higher than the intermediate-term support level and, finally, a rally to fresh new highs on strong volume.

Take a look at each of the charts below, and I'll tell you the best call options to take advantage of these bullish patterns.
