The Gold Bugs Index is advancing on a 588.31 target that would have been a piece of cake were it not for a series of peaks just below the all-time high at 598.36.  Looking at a much big picture (see inset), there are two numbers we should jot down:   661.07, a ‘D’ target that could be described as “minor” only in the context of the monthly chart: and 634.64, the maximum high that can be inferred from the monthly chart.  They both look like high-probability bets, although it would imply a minor-trend extension of the major trend to reach the higher target.
