NZDJPY: Trading Plan for US Session

NZDJPY reached a major daily resistance level yesterday.
today the price is quite weak and we see minor fluctuations within a narrow trading range.

on a 4H chart the price has formed a double top pattern.
71.6 is its minor support.
I want to see 4H violation of that to initiate short trade.

goals:
71.0
70.55

in case of a new higher higher higher close on 4h, setup will be invalid and bias will switch to bullish.
