To Gunawansastra...
Personally I don't know where Indonesian professional traders place their investment funds.
Thanks.
@ gunawansastra:
Large traders from Indonesia usually trade with brokers that are properly regulated by trusted regulatory bodies such as CFTC, NFA, MFSA, ASIC, FCA. One of the top brokers that is a favorite is Interactivebrokers, but the minimum deposit is also relatively large. Other examples can be found at brokers regulated by the FCA such as FxPro and ThinkForex also have ASIC regulation.
