I was checking a Canadian stock quote an hour ago and noticed that it was stuck at 1:39 p.m. The US tickers were working as usual. A halt, perhaps? Nope. The whole Canadian stock market had frozen.
The TMX Group says technical problems have affected the Toronto Stock Exchange, Montreal Exchange and other markets it operates.
The Toronto-based company issued a series of notices by Twitter to alert all users of its trading services.
This is embarrassing:
UPDATE 4 - TMX has decided to shut down all markets for the remainder of the day. Trading will not resume today, including market on close. We apologize for the inconvenience. Further updates will be provided.— TMX Group (@TMXGroup) April 27, 2018
It wasn't a crazy, high-volume day. So, what happened? Did some diversity hit the fan?
