Good news: the market's emergency selling preparedness test has been successful:
- U.S. OPTIONS EXCHANGES RSUMING TRADING AFTER OPRA ISSUE
Update, as supposedly things are unbroken again:
- as of 12:51 the CBOE and C2 are reopened and available for trading
It's just getting silly. Just like last week, [5]the CBOE's OPRA has just given up the ghost.
And promptly, BATS "self-helps" itself against OPRA:
- BATS TO HALT OPTIONS TRADING FROM 1:30 PM UNTIL OPRA RESTORED
- BATS OPTIONS HALTS TRADING AT 1:30PM ON OPRA ISSUE
Curious where the stock volume has gone? All in the derivatives, as everything is now an ultra-short term bet on micromoves in underlying securities. Hence, now nearly daily breakages.
And now Nasdaq:
Finally, IB chimes in:
- Due to OPRA data dissemination issues all US OPTIONS trading venues have halted trading.
In other news, this is merely the exchanges appealing for help and screaming: please stop selling AAPL.
