We would like to know what will happen with Chain RIC of most active on HKEX, AMES, NYSE, NASDAQ(example RIC below). During the market close, pre-auction, call-auction period. Are chain RICs of most active stock list always available during all time? or there was a time that it returns a blank.
Thankyou[Chain RIC]TopTurnOver . AM.HK .AM.XAX .AM.NYA .AM.IXIC
