The latest fashion in town is the Hong Kong listed CW.
I know one can get free historical data from Yahoo. But to do it manually is too tedious. So I discover this tool called Yahoo Historical Quotes Downloader. Oh...i know of this tool long time ago. The first version that I used was a Java version that requires one to type the command in DOS prompt. Not user friendly at all. That's how my friend got the KLSE data from Yahoo before they discontinue the services. The next version that I tried comes with a GUI, unfortunately, it didn't work. I don't know why. But the latest version works almost perfectly. The free version allows you to download only 100 tickers at one time. So for HKEx, just repeat it a few times to get the complete database.
For daily updates, just go to eoddata to get it free.
So, to do TA on HK shares, get the ticker list from eoddata. Use the ticker list to download the historical data from Yahoo. Their data starts from year 2000. So its sufficient to do TA.
Not only that, you can also get SGX daily shares data. Okay, only one CW from SGX. Maybe it there will be more.
