GLD is the symbol for the NewGold ETF. The price is the Rand price of an ounce of Gold less admin. The weekly chart indicates that a new bull era has been entered. Generally known as paper gold due to the Fund needs only a nominal amount of physical gold in order to operate the Fund. In this way the supply and demand equation for the metal is overpowered by the false demand and the price of gold is thereby intentionally suppressed. When you buy the ETF you are assisting the price control (suppression) action of the underlying commodity. No guesses for who is the biggest buyer, but as with all such taxpayer backed manipulations the excuse is that it is for the greater good. Hence pick a commodity that you want to suppress (for the greater good) and go for it. Further down is the daily chart.
Sideways action means passing through the same price range repeatedly. Programmed trading systems typically cause clustering at round numbers. Inside information on the most active programs can be leaked out to dupe punters before the program is changed by market maker interests for enabling their collection of windfall profits from their duped muppets.
The "cash" index is operated by a market maker. These outfits operate with a conflict of interest when they also act as brokers. The practice is clearly questionable and I believe it should be outlawed.
