EURCAD expected to drop to 1.53 level
Today is Bank Of Canada Interest rate decisions (expected to be unchanged) which means the asset will become volatile in the next 2 4h candlesticks.

If it will drop because of the event, i want to already have a sell position before that time.

If then, the event causes it to rise, i want to be able to sell it again even at prices of 1.565 and 1.57
