Kylie: All of the above forex brokers accept clients from Indonesia. I recommend interactive broker and Saxobank.
This is the challenge faced by many Indonesian traders who have been able to consistently profit from trading and want to develop their accounts. Many brokers are licensed by top regulations, but when Indonesian traders register, they are directed to offshore regulators. That's why I wrote clearly the brokers above, because some of them are not stipulating offshore licenses. Interactive Brokers, Saxobank, Oanda, City Index, Swissquote do not have offshore licenses even when Indonesian traders register with them.

Ross: do they accept clients from Indonesia? what is the best broker according to your experience? Indeed, Tickmill UK is regulated by the FCA, but it's funny how clients from Indonesia are directed to offshore-regulated tickmill. 

Neil Rampling: Saxobank, Dukascopy, FXCM, Oanda, Swissquote, Forex.com, City Index, IG, ICmarkets, Vantage FX.

Ross: So, which broker should I use?

Neil Rampling: In my opinion, it is not safe for large capital traders because the regulations from the SC (Seychelles) are not 100% safe. There is a more secure Tickmill regulation namely FCA UK, however, Tickmill UK cannot accept clients from outside the UK. Non-British citizens will be directed to the Seychelles-licensed tickmill.

Neil Rampling: It seems safe to use large funds on tickmill, I've seen a list of deposits with a $100,000. In Malaysia, traders also like tickmill since they have a specific account types for large capital traders. for me personally, I'm still trading on tickmill.
