judging from ur question seems like ur not familiar with forex.
have u open a demo account yet? better learn MT4 basics, analysis and basic money management before u go straight to live account.  instaforex also have demo account.. Dont be too enthusiastic, its easy to earn money using forex..its even easier to burn your money too.  If you want to open Live account all u need is a credit card and a PayPal account.  Most broker are bucketshop and market maker.. better to open ECN broker like Dukascopy but need minimum deposit USD1000.

i'd trade with insta but no offense but when i trade demo, everything went smoothly and nothing wrong,
but it was diff when i trade live, always requote,invalid price, no connection etc .. and also its 3pips spread, not suitable for me since im a scalper..
my 2 cents ..

Six months is enough time for demo.  As long as u trade risking no more than than 2% per trade dont have to worry.  When i start trading live account, i start with 0.01 lot trades and gradually risk higher lots as my confidence grow but i wont risk more than 2%.  Choice of broker depends on your trading plan.  If you hedge or use big leverage then u must avoid US base broker.  I would avoid the smaller brokers and rather go to bigger broker like MIG bank, Oanda and FXCM.  This is to make sure that your broker is liquid and they dont trade against you.  Instaforex has a big customer base in Asia and good support but i doubt them because of their aggressive marketing.. thats just my opinion.

if i not mistaken their minimum deposit is $250. my friend used them before, no problem with any withdrawals so far
