IBKR will do but if you meant if they offer KRX securities then the answer is "no". $10k really is not a high minimum.
for me it is. plus im new to trading. if i have 10,000$ in my account the undisciplined idiot will come out and bet it all
Would IG suit your needs? South Korea is listed in their country of residence select field. Also, paper trading should suffice.
Well, that's a different problem that could affect your effectiveness as a trader. Consider attending GA. (I am). As for being a new trader, I would then make the recommendation to trade only US stocks with a US broker. Information is more accessible and you can easily bounce of ideas with other like minded people for accelerated learning. Unless of course, you spend your days with a bunch of Korean traders. d08 is an excellent example of those geographically mobile traders (International Player) who is "plugged in" locally. Yet, he still focuses on different markets. That's it for me. Any more insistence like a know-it-all uncle and I will get flamed. Good Luck
IG is much more expensive than ETrade, never mind IBKR. I honestly think the only people who use their services are the ones who don't know any better and sign up because they have so many ads on TV.
If you calculate the cost of trading for IB vs IG vs ET you'll see how their relative costs change with size. You could create a share size / transaction cost chart. Considering you want to start with a sub-10k account, you'd probably be wise to start trading at sub-100 share size. E-Trade is not competitive for short-term trading with very small size. Calculate your costs, for example for 10 shares, 25 shares, 100 shares, 200 shares, 500 shares, ... IB will be cheapest for all of these. IG will be cheaper than ET up until about 200 shares. Paper trading is the cheapest!
