With the implementation of Holiday Trading, we will continue to conduct adhoc margin review for H products on H Days (i.e. the effective day of increased margin rates can fall on H Day).

Nevertheless, for the scheduled monthly margin review, the effective day of new margin rates for all products including H products will remain as the next HK Business Day (i.e. not fall on H Day).
