Gold (GC) Analysis, Key-Zones, Setup for Thu (Aug 20)Gold FuturesCOMEX:GC1!MyAlgoIndexBias: Bullish into Thursday. Gold broke out of a multi-week consolidation and settled at 4,545.3, up 124.7 points (2.82%), with the day's range from 4,378.0 to a 4,582.8 high. The catalyst was a clean macro tailwind: the Treasury signaled long-end support to cap borrowing costs, which sent the dollar index down 0.85% and the ten-year yield down 1.13%, the two cleanest inputs into a gold bid. Notably the post-settle electronic session pushed above the settle toward the day high, so the market's late verdict was even more constructive. Price recaptured the 100-day average and cleared the 1.272 swing projection at 4,540, with the 1.618 at 4,585 nearly tagged. Short-term momentum is strong but stretched (relative strength near 69, stochastics saturated, directional index at 38), so the preferred stance is buying a controlled pullback rather than chasing the highs. A sustained break back below 4,420 would flip the breakout to a failed move. Resistance: 4,542 recaptured shelf and pivot resistance 4,582 to 4,585 session high and 1.618 projection 4,591 third pivot resistance 4,609 relative-strength 70 level 4,693 prior swing high Support: 4,536 to 4,542 recaptured shelf 4,487 to 4,505 first standard deviation and pivot support 4,432 daily pivot 4,420 previous close, breakout line 4,378 session low 4,371 first pivot support Primary Setup: Long on a controlled pullback into the 4,487 to 4,505 support base holding, targeting 4,542, then 4,582, then 4,609. A stop belongs below 4,420. Alternate: a clean, held break above the 4,582.8 high targets 4,591, then 4,609, then 4,644. Stand aside on a dollar and real-yield rebound that breaks 4,420, and into the 08:30 ET data and the 11:10 ET Fed speaker until the reaction is clear.
