Gold traded sharply lower on Sep 16. The move resulted in a break of support at $1774.5, Aug 19 low and a test of $1745.4, 61.8% retracement of the Aug 9 - Sep 3 rally. The retracement remains exposed. Further out, a deeper decline would open the key support at $1690.6, Aug 9 low. On the upside, initial firm resistance has been defined at $1808.7, Sep 14 high. A break of this level is required to ease bearish pressure.
