Quote from NetTecture:
Maybe he is also just staying there for other reasons, like taxes. "Staying in Hong Kong" does not mean "Trading in Hong Kong". I am not sure you heard of it, but especially when doing automated trading you can "rent" or "colocate" computers in other countries.
Talking as a German living in Poland (for tax reasons) with trading interest in the USA.
Yes, but sound like he is doing HFT with his own program. May be he can somehow rent a server near wall street to HFT in USA while he sleeps?
