USDCAD-Expecting a strong correction-Expanded flat

Hello, im closely watching this pair because it seems its ready to make a pullback/correction.
Looking at D1 chart we see an expanded flat correction could be forming for wave 4 circled. The AO also shows double bearish divergence:

Im trying to pinpoing an entry on H1 chart, price is making an AB=CD retracement to last highs.

I assume wave 1 blue is a leading diagonal.

Details on chart.

Regards.
