关于取消TRADE

AGA7d

“NASDAQ OMX reported that we had no technology or system issues associated with the trading that occurred between 2:00 p.m. and 3:00 p.m., ET,on May 6,” according to the exchange.  That allows it to place the blame elsewhere. Using an arcane rule, NASDAQ said it will simply reverse a number of trades. “We have coordinated a process among U.S. Exchanges and therefore, pursuant to NASDAQ Rule 11890(b), NASDAQ, on its own motion, will cancel all trades executed between 14:40:00 and 15:00:00 greater than or less than 60% away from the consolidated last print in that security at 14:40:00 or immediately prior.”

所以只有极少数的TRADE会被取消，在那二十分钟里跌了60%的股并不多
