Because it was not the canadians but americans using TSX, which had to be open for trading. Also consider the possibility that it was canadians moving over onto US exchanges July 1 that may have brought the price up on ECU - now there is an idea.

I repeat again, today there was no small lot orders and the Bid-Ask differential took twenty minutes to close within yhree cents on my gold stock example which is Nevsun (NSU).

I was embarassed to post it's name because I sold some of their shares with another gold stock and bought ECU, am at a slight loss for it.
