OSK is introducing structured warrant from Hong Kong. Wow, now I can diversified a little bit. HKEx stock codes can be found here. There is a link to the stock price too. I have been collecting HKEx data since 2005 from eoddata.com. Not very complete as I need at least 5 years for a thorough analysis, but sufficient enough to play for short term. Any reader knows where I can get free historical data for this exchange beside the one I mentioned?
