Gold retreats from record high above $1,900/oz (I feel sorry for the suckers who bought gold recently)  By Jan Harvey

 (Reuters) - Gold prices retreated more than 1 percent from record highs on Tuesday as a recovery in appetite for assets seen as higher risk, such as stocks, took the steam out of a rally that many saw as overdone above $1,900 an ounce. 
 A hike in margin requirements for gold forwards on the Shanghai Gold Exchange also helped curb the precious metal's scorching rise.
