After looking at @haejin analysis on GAS (which he also pointed out a cup and handle formation), I've noticed another cup and handle formation over the last two weeks on the 4 hour chart.
You can see the left side of the cup was formed with high volume. The bottom of the cup was formed with decreasing volume going down and then increasing volume on the way up. At the right lip of the cup you can see a pull back on lower volume. You can read a more in depth explanation of a cup and hand pattern here:
What I would watch out for is a break upward from the handle with high volume confirmation.
Trade the trend - the trend is your friend!
Good luck!
