Thanks for reply.

If that's the case, I think I'd look for other Gold investment tool which price follows the trend of global price movement. I don't expect 100% synchronize. But at least follow as close as possible. For example, if today world gold price dropped a 3%, I would expect HG price follow drop a 2.6-2.9% perhaps, real-time if possible.

Well I am not an aggressive trader. I am just trying to buy gold at a good timing when price is decent, based on technical chart. That's why I was asking, is there a time lag between world gold price and HG price .
