Well, it is commodities :) Why? It can be very subjective, but I just got excited by the first book of "Market WIzzards" where guys made fortunes trading commodities. Of course now it is a different time. But still, commodities present attractive trends. Just take recent cocoa's boom or gold's price surge😎
Tredero did well providing me these assets. Through the broker I have sufficient leverage to open meaningfui positions.

It depends on the market situation. I think the majority of traders do it this way.

They look at the market and the opportunities it gives me. And then I choose the asset.

For the most part I trade stocks, but recently I traded some commodities and energies also. Because of the geopolitical situations I had decent profits from oil and cocoa.
