The hourly chart below shows crude oil since I last posted on this subject in late May and earlier this month:
The daily chart also depicts a bullish picture:
With this recent rally, crude has successfully broken out of a triangle formation. $100 looks to be an area of potential resistance given it approximates last September's prior high and is also a nice round number (don't dismiss the importance of round numbers, review behavioral finance studies). Again, it wouldn't surprise me to see a pullback take place soon before a run at new highs occurs.
