GBPCAD - A potential shorting opportunity to 1.79 zone

I am favoring a move lower in GBPCAD since price is at a major resistance zone.
I can also observer a hidden bearish divergence (price made a lower high while stochastic is making a higher high).
Stochastic is also in the overbought zone.

** Given the drop in OIL prices, GBPCAD may still rise to 1.85 zone. So, I will drop to the H4 & H1 time frames to try to see bearish signs (i.e. bearish candle stick formations, H&S patterns, etc.) before shorting.

** No trade is taken until now
