GBPCAD-Ready to begin a downtrend-wave 3 starting

Unlike the GBPAUD, this pair is ready to make a big decline because at D1 chat price broke a clear uptrend channel making it first LL (lower low).
Convergence on macd signals the direction of the next move. Price is now making a retracement and we should find an "ideal" entry point to continue the starting downtrend.
Here on H4 chart we have:

- Price retracing to 0.50 fib (not shown)
- Expanded flat correction seems complete
- Previous wave 4 acting as resistance
- Pinbar shows rejection from the strong round number 2.05000

This could be the start of wave 3 blue (in parenthesis), so a big decline expected.

Regards.
