FYI: (If link doesn't work, Google article title.)
Nasdaq has mistakenly allowed more than a thousand trades to be executed around the market open and close, an error that it said prevented other investors from getting their orders filled at a crucial time of the trading day.
In an alert to the market, Nasdaq said certain orders, called minimum quality orders, were mistakenly included in the opening and closing “cross” where outstanding orders are executed.
