Have traded both at same time for years. No longer trade forex, not because it is not profitable but there is to much to stay on top of around the clock. I really did enjoy trading it.
Just to much to stay on top of both markets, so I choose equities, I also like to sleep at night. Its easier to turn off equities after the market closes and have a life, but forex never sleeps, and your mind never leaves it, even when your away from the screen.
If you do trade forex, only trade one or two different pairs until you learn the beast. Prepare for long periods of low volatility, interrupted by sometimes huge moves .
Most indicators, technical patterns you can throw in the trash. Avoid all gurus.
Good Luck.
