The SPX met with strong resistance at 1811 in November due to the Uranus' position, reinforced by the square to Pluto and Jupiter and opposition to Mercury. This price level was first rejected on November 29, then re-tested on December 9, 18, 19, finally breaking through on the 20th. Neptune gave previous resistance at 1775.
We may see a re-test of 1811 before a continuation higher, since prior resistance levels often get re-tested as support.
The next strong resistance comes from the Moon's nodes, currently at 1836 and slowly falling. On the important January 7 date we are watching, the South Node coincides with heliocentric Neptune sextile resistance at 1834.75.
Gold hit resistance from Pluto on October 28 at 1361, reinforced by the square to Uranus and opposition to Jupiter.
My guess is that gold will find support at Neptune's square at 1145, which is reinforced by the Mars opposition on December 30. The Uranus-Saturn-Mars Golden Triangle at gold's 72° harmonics adds to the significance of this turn date. These aspects are also discussed here.
Saturn reaches gold's 72° harmonic January 3 and may give more clues at that time.
