When trading Canadian Retail Sales, I recommend that you open and close your trades within the first 45 minutes of the report, because after 45 minutes, there will be other non-related market forces that will be affecting the currency pair.
With this Retail Sales report, it's quite simple. If you can get in within the first 15 pips of
pre-release price, most likely you can get away with a 15 pips
stop/loss and a potential profit of 20-30 pips or more. If you cannot get in within the first 15 pips, I definitely wouldn't chase it. Wait for it to
retrace within the first 5 minutes, and if it doesn't, then skip the trade.
Of course, the move will depend a lot on the difference between actual number and expected number. If the difference on the core Retail Sales is over 0.5, then you could even try to get in within first 20 pips.
I recommend trading USD/CAD on this report.
