Gold is manipulated. There are at least a dozen "charts" and you may be better off by closing your eyes and throwing a dart.
Example:
Comex Gold – Weekly, semiannual and annual supports are $801.7, $796.5, and $729.7 with a monthly pivot at $870.5, and semiannual and quarterly resistances at $938.2 and $981.3. From

When to buy? Best to ask when to sell.
