Neither- they aren't going to allow oil to go up (as alternatives will become viable), and Opec won't want it dropping too much.
As you have mentioned 'trading' rather than 'investing' in the heading no reason why you cannot trade either of them,the only requirement to trade commodities like the 2 you have mentioned is movement if the price moves you can trade it 'long' or 'short' its when a price does not move you cannot trade it.
I'm confident Gold prices will continue to rise dramatically as the dollar keeps losing value over the next few years.
Neither.....good money is in silver because it needs to catch up to gold and will sooner or later. Benjamin Ehinger
Trading either is like gambling IMO. I prefer accumulating a bit of physical bullion to hedge against central bank malfeasance.
For the time being the invest in gold seem charming but it according to be trading Oil is beneficial more than investment in gold.
you can make more profit with fluctuating oil prices, but gold is actually the sound investment option
