Some thinking about technical vs. fundamental on commodities

Hello all,

recently I was thinking a lot about trading commodities.... I am very inclined to use the SMR trading method (like in Chick Gosslins book). The SMR method uses the LBR 3/10/16 indicator mainly, so it is using purely technical oscillators.
Now... considering that fundamental data plays a major role in commodities (political issues, droughts, floods, weather in general, etc..)..... doesn't this nearly totally render technical analysis implausible?

Hmm... I am thinking about this a lot, maybe you have any answers....

Thanks and many greetings,
Oliver
