Equities because they are straight forward and simple. I will complicate things with options a bit when I get more advanced haha
Spot fx, because it's accessible to retail 'average joe' traders and a good insight into trading. I will move over to futures once I raise enough capital.
forex, because I have already traded everything else, and it's the only one I don't have any bad memories about (yet.)
Equities, ETFs and options. Mainly because of diversification, arbitrage, statistics, etc. I trade FX sometimes for fun, and SSFs and other spreads when I have idle cash.
Even though I average around 500 to 600 trades per annum among my three accounts - a taxable and two IRAs, according to this poll I must not be a trader since my trading tool of choice are open end equity and bond mutual funds. That's because of their persistency of trend and lack of volatility compared to other trading instruments thus allowing one to more easily deploy their entire trading capital to best capitalize on the compound effect. Of course, that's yet another reason I must not be a trader since I abhor volatility.
