Gold has tested the 1815-1818 2 times because of the weak USD index and US Hong Kong sanctions fear. There is a big gap from 1768 to 1775 and gold will make a correction if the USD index makes a recovery of recent sell-off and the US softens its stand on Hong Kong crisis.
The 1768-1775 is an important zone to watch for gold correction. Gold will drop fast after breaking the 1768-1775 and it may drop to 1740-1745.
However, gold will continue to go to 1850 if gold cannot drop bellow the 1793-1795 because demand for USD will be decreased if China stops using USD for international and commercial transactions
