If demand is falling and the nervousness about world financial markets receding then you have a good reason to take profits. I have noticed the price quite often tops out in Feb/March and this may be no different, only time will tell
I worked for a guy that made millions trading Gold in the late 70's early 80's. There was another guy there that worked for him, the difference was: one sold and the other didn't. :-)
My hunch would be, that since we have had a good fall, it will continue. Commodities tend to trend and levels seem to be: 975 960 940 900
