Looking for a bearlish butterfly in GBP/CAD after bottom formed

Look at the chart, Now a head and shoulder bottom is just formed last night! But a bearllish butterfly is going to formed (1.618xa and 2.24-2.618bc).
It might mean that price is going to pull back toward neckline, test it and will rise again!
If the butterfly is formed, short it and targit at the neckline
If the price is down before the pattern, long it around the neckline

Thanks to technician's idea
