Short GBPNZD from H4 supply zone, targeting daily support

On the weekly chart, GBPNZD is once again pushing through the top of a large range, but my expectation is that it will once again fail and fall back to much lower prices. Therefore I am looking for opportunities to short.

The daily chart shows price retracing down to resistance turned support. This looks like a good initial target.

The H4 chart shows the clear downtrend as price retraces. I am looking to enter as price pulls back in that trend, directly into an H4 supply zone.
