GBP/CAD ;Buy zone

I'm looking for buys on GBP/CAD on this area because:
it's at the gold zone of the Fibonacci retracement
its where the trendline liquidity lies
it will be clearly over sold
overall trend is up
I would be looking for a confirmation though like double bottom or reverse head and shoulder.
it's a trade that I am also looking to scale in as I go into profit
