NZDUSD - Bearish Shark

On the 15-minutes chart, there is a Bearish Shark Pattern that has formed up and it's valid for a shorting opportunity.
There are 2 concern about the setup,
1. 1 rule has been violated while the Shark Pattern forms up.
2. A long shadow candle form could be a warning sign.

I will be waiting for the retest of the pattern at 0.7225-0.7229 for a shorting opportunity that gives me an opportunity to stretch my target.
