Silver is making new yearly highs (currently Spot Silver has already traded as high as $17.18) while gold is not making new yearly highs while Mars is turning retrograde. This is a classic sign of gold exhibiting an intermarket bearish divergence to silver. Watch out!
Gold needs to trade above it's most recent high of $1287.80 (March 11th intra-day high) to maintain this bullishness in the precious metals.
Also, according to Merriman Mars goes into the first 6 degrees of Sagittarius from May 4th to May 27th and this is normally bearish for gold.
