AUDCAD-240-Buatterfly harmonic pattern

Hello guys;
Honestly I have found a harmonic pattern on AUDCAD on 4H time frame which needs to approve buy candlestick and trend line.If this pair get back to uptrend and was broken by downtrend line 1 through the PRZ , after pull back we can get a long position and we will follow the pair till downtrend line 2 if candlestick could broke we stay with our long position till achieve our T.P 1&2 if it couldn't we can close our long position.
Cheers.
