re: NASDAQ to cancel trades

No, you are totally wrong as you are about 80% of the time.

Your assignment for today is to find out what an exchange is supposed to do.

Hint:... An exchange exists to discover ______?

It's about time someone explained to you totally wrong headed, highly educated, clowns why Mr Market always wins. You don't get it now and you did not get it two years ago. What the flock have you been taught? Nada. You pay good money to listen to clowns that don't know how a free mkt works? That makes you about as dumb as those that bought 'really shitty deals' from the GS prop desk...

You will need an entire reeducation when this crap really goes down. Perhaps you should start reading the Austrian economists? Get a leg up? Good luck to you.
