I trade a bit of everything.
Forex, stocks, indices, options, commodities...
Here's the PROs and CONs of trading everything:
Pros:
There is always a trending market somewhere... with a diverse list, I can usually find a setup pretty frequently that has a solid trend + fundamental / macro setup.
Having a bigger list of assets is especially useful for swing traders. Otherwise, weeks can go by without a setup.
Cons:
This means I have to monitor more charts, and new traders should probably stick.
