I think a lot of today was based on fatigue as you suggest but I suspect that Gartman pulling out of gold had some effect. When he recommended to his subscribers that they sell Canadian oil and gas plays there was a massive selloff. I don't underestimate his influence.
He said he's bearish on gold for the first time in 3 years. Part of his position was that he felt there would be government interventions into rising wheat and food prices.
