Eur/Cad (I added a buy stop)

I want to buy this because price made a strong move down in the trend!!! The pullback could be 170 pips!!
I am afraid to enter a buy right now because price is so low, that im afraid manipulation could happen!!

So I added a 15 pip buy stop and im trying to buy the next wave up in the downtrend!!! This is a counter trend trade by the way!!!
