Hi, I have a question regarding HSI premarket bidding. HSI is traded from 0945-1230 / 1430-1615 local time. Sometimes I want to take part in the pre-market bidding before the open of either AM or PM session, from when to when is the time for this pre-market bidding ? And if you have made the bid , can you cancel it later but before the open of the market ? Thanks for any help
you can enter and modify orders up until 4 minutes before the open. you can enter only auction orders up until 2 minutes before the open but can't modify after 4 minutes before the open. http://www.hkex.com.hk/infra/dertradmech/pmdetails.htm IB supports these order types and they should be explained in the manual. If you have questions, please contact the HK help desk who can provide further assistance.
