I put this chart together back in January and its been a solid roadmap all year including the bounce we saw last month.  Now we find ourselves precariously close to ~104 level from which a break could send the index to 60 in a hurry.  As you can see the range between 60 and 104 has only been traded for about a year over the past 16 years, effectively representing a gap where shares could plunge if and when support gives way.

In terms of today, the GDX/GDXJ support breaks on these charts should be confirmed on the open and I expect a very impulsive move down.

On GLD, watch to see if 107 support can hold.
