So perhaps I can share my own plan for 2020 and inspire some others to also share their thoughts for the coming year.
A couple of years back I started expanding from pure FX towards commodities and indexes. I started with Crude Oil and that was fine until the trade wars put a lid on prices. Then this year I started with SP500 and that has also been great all year. But I suspect we may be entering some unsettled times with it next year and so I am looking for something new again.
So I have decided next year to try trading what is possibly the oldest currency in the world (outside simply bartering) - Gold.
This is a brand new commodity for me and I want to learn about it as a commodity alongside actually trading it. E.g. its history, industries, production, distribution, markets, and so on.
I am currently pondering whether to open a new thread for this purpose and am exploring some ideas about this.
