Where can i buy crude oil?
I presume you mean where can you buy something that represents the current price of crude oil? You can do so via a commodities broker, through futures contracts, or you can do so by buying and ETF, or multipe ETFs, through your current broker. Oil ETFs are designed to track/reflect the current price of crude oil. They aren’t going to be exact, but pretty close. By design, when the price of oil rises, so too does the price of the ETF, and when it declines, again, so too does the ETF. I have to tell you, though, that trading oil contracts and futures is much more complicated than trading stocks.
