Is this an IB specific issue or is it the TSE directly?
On IB's status page, it simply says:
To TSE Traders:
TSE is currently unavailable for trading.
Of course, I didn't receive any alerts about this. And to top it off I'm stuck in a trade I've opened before 10:30 (bought 2x short TSE ETF, HXD.TO)...
I figure if it's a TSX issue there would be some news / bulletin shown somewhere on TSX' website but I didn't see anything there.
