I'm not sure you would have made anything in the last 25 years.
At Christmas I saw crude oil at $37 bbl and though buy, that's as low as it's going for now. I missed it and it peaked at £53 bbl at new Year..
I didn't know how to buy commodities..need to look into that.
Would I need to buy futures or could I just buy oil at a spot price.?
btw - much more convenient to buy the oil ETC - no need to store the oil
