On Wednesday morning around the market’s open,?New York Stock Exchange parent NYSE Euronext (NYSE:NYX) said it had a short routing problem that could have resulted in trades not being executed at the best available price aka???trading through protected quotes” in trading jargon.
According to FOXBusiness’ Matt Egan, in an exchange alert, NYSE Euronext said that between 9:30 a.m. ET through ?9:34 a.m. ET, NYSE and NYSE MKT exchanges had ?experienced a brief issue? routing orders to the following three exchanges: Direct Edge?s EDGA and EDGX exchanges and a platform that is run by the Chicago Board of Options Exchange (NASDAQ:CBOE).
In this four-minute span, NYSE and NYSE MKT executions ?may have traded through protected quotes from those exchanges.?
Protected quotes from other exchanges had not been affected by the hiccup said NYSE; the problem had been fixed at 9:34 a.m. ET with traders receiving an alert that said, “All NYSE and NYSE MKT systems are functioning normally.??
This latest snafu comes after BATS disclosed last week that over a four-year period, its customers may have lost $420,000 from a system problem.
