1. The exchange rate will now be set each week according to the average market rate over the last two weeks.
2. The exchange rate will be changed every Friday at 16:00 (UTC+8), after the delivery of the current week’s contracts. The exchange rate will not be changed before delivery/settlement so that users current positions are not effected by the changes.
3. The exchange rate adjustment threshold will be set at 0.2%. This means that if the deviation between the two-week average market rate and the current system exchange rates does not exceed ±0.2%, the system exchange rate will not be adjusted. Only if the deviation exceeds ±0.2% will the system exchange rate be changed to the two-week average market rate.
4. In order to avoid impacting users with a jump in exchange rates, the system exchange rate will be used in place of market exchange rates prior to 27th March during system exchange rate calculations.
