Quote from Copernicus:
can a US Citizen open an account with them?
You can be any country citizen but if you hold a HK ID ( permanent or temporary resident ,it is much easier).
I am not sure HK brokerages allow non HK ID holders to open securities trading a/c over internet. But if you go there, sure you can open a/c with your passport & overseas address & send wire.
I have traded with reputed HK brokers like
Sun Hung Kai securities
Hang Seng Bank securities
Dah Sing Bank securities.
DBS Vickers Online (Singapore,HK,Taiwan stocks)
The commision used to be high those days. (0.18-.25!!!!!!)
Internet platform medicore & no charting.
Stick with IB if they offer HK stocks.If you are a serious chartist, subscribe to some serious chart service that offer HK data too.
Nowadays I trade only asian ADR's at IB.
Do not forget to keep your eyes on
