The 2×1 downtrend line that fell from mid-April accommodated the shocks from August to October and became the resistance of gold's rise, causing prices to fall when they touched the trend line. When the gold bottomed out, we can see that the 2×1 rising Gann line played a supporting role in the upward trend in October, and will play a supporting role in the retreat after the gold price reached 1243. Support is seen in 1204-1200.
