FX:USDCAD   U.S. Dollar / Canadian Dollar
There are many economic news that can create more volatilty than usual for the forex market.

One of which is the Central bank raising interest rate such as Bank of Canada raising it to 1.25% by 25bp.

That is why selling high , buy low become crucial so that your SL would not be hit easily , taking you out of the game and having to re-enter at a much lower price. If you are not in yet, then occasion like this , one can stay away until it is stabilise to avoid donating pips/profits to Mr Market unnecessarily.

Best of luck
