Here are some, but not all of the reasons I'm short at the moment.
1. Weak sentiment for gold.
2. USD down and gold's going with it.
3. USD is picking up after Yellen comments.
4.The trend line from 2011 is still intact.
5. Possibility of a break below $1,200
6. Double top confirmation with a min. target of $1,140
7. Possibility of break of the trend line from the beginning of 2016.
