Gold prices test Thursday's low.

The case for gold shorts is improving and a break below support would be the best sign yet. A $32 decline since the FOMC decision leaves gold at $1178 and testing Thursday's low.

In the bigger picture, last week's low of $1175 is the more-important support level. If it gives way, look for a return to the March low of $1144.

Update: Wooosh. Down it goes to $1172 in a heartbeat.
