I'd say if you want to become a millionaire really quickly trading forex, then start with 2.:clap:
Seriously, why not just trade in SIM until you know what you're doing, technically? I've never bothered with micro lots, can't see I'd have the patience to manage a trade properly when their was so little to be gained. Once you've got a better idea of how many pips you are risking on each trade, you'll be in a better position to determine what sort of account you'll need. For example if you're stops are at 20 pips you might be ok with a mini account, but if they're at 200, you may want a micro account so you're risking less $. We can't answer that for you, you'll need to determine your risk tolerance.
To determine your risk tolerance, have a think about what amount of money you're prepared to lose on a position without getting too stressed. Imagine how you would feel if you spent $5 on a coffee and it was crap, would you be really pissed? I would think not. How about $20 on a meal, and you had to chuck it out? I would advise starting out only risking only what you're comfortable losing.
