open an account with jupiter first, you need to go to their office to do that.

then go to hwangdbs and ask to do a share transfer if you want to move all your existing shares.

usually how it work is,
1. you key in your order
2. order gets sent to your dealer's desk (terminal in this case)
3. dealer confirms the order
4. order gets sent to bursa server

The whole process takes about 2-3 seconds. I think the dealer confirmation part could be just an automated script. Sometimes, there is some delay and it is usually caused by the dealer confirmation process.

AFAIK, its jupiteronline, RM8 minimum.
