Main main two brokers are Tickmill and ICMarkets, their Seychelles branches due to 1:500 leverage available. No problem withdrawing your money. Use only brokers with variable spread and NDD. Brokers with fixed spread are keeping 'in house' your trades, never sent them to real market.
The broker i use is called MOGAfx, an Australian broker regulate by ASIC. 1:500 leverage available, many different of account for option ( standard, VIP, low spread, 0 spread), also have copytrade system for those who does not know how to trade. Really nice account mangers help you with anything.
FP Markets is a good choice. I have been trading with them for a while now; their spreads are some of the tightest out there (at least in the major pairs- Averages 0 for most part of the day in EURUSD).
If you choose their Raw Spreads account, the commission charged per lot is 6$ per round lot, slightly cheaper than other similar ECN brokers.
