I do not know if this Canadian thing or if this issue affect the US version as well.
ET which used to trade on NYSE has transferred its trading to the new TXSE. It appears to have happened on October 20 because the trading price of my units of ET no longer update today. I checked a few times but price history has ended as of October 20 as well.
Do we need to add a prefix for TXSE like we do for securities on the TSE?
