I think the rally we are seeing in crude oil (/CL) has some legs and we will see $70s again, says Carley Garner of DeCarley Trading. She is watching the weekly trendline on the chart. She sees uptrend in the short run but in the long run, she thinks oil is weaker. I still believe that crude oil will pull down some stock markets, it's just a matter of when, not if, she adds. The U.S. Dollar (/DX) and crude oil are highly linked, she says. She is looking for a weekly close above $94 on the U.S. Dollar.
