CAD retail revenue and GDP data are coming out in the exact same time (8-30AM EST). Moreover, USD GDP and maintains data will be published at exactly the exact same time.

For way to exchange would be to await the amounts and it could be a move that is very nice even when one input after 1 or two minutes, when all of the data point to the exact same direction.
