Commodities are great fun but not all commodities contracts were created equal. I am forever shouting at the TV journalists who don't make clear distinctions between LME style trading where there is an actual lump of metal and gold trading where there is ... well ... sort of nothing behind it.

I feel incredibly ignorant about algorithmic trading strategies, it is definitely something I need to learn about. Perhaps my view of trading is a little Jurassic... I suppose to me a strike at a mine would affect the price of the metal, but now it seems that the volume of trade resulting from the strike at the mine is the market mover, not the strike itself! There is probably no need to even be aware of the strike, just the consequences.

(I am supposed to be writing a talk at the moment and all I want to do is start researching more about this... steemit does tend to throw me of focus sometimes.)
