chart analysis for gbpusd

we see gbpusd currently forming an head and shoulder pattern on D1 and H4 timeframe. I ex expect a little bullish move when market open and then sellers to come in and push downward to form the second shoulder of the pattern nevertheless if there happens to be strong bullish move that breaks the resistance, then i will be waiting for a retest before possibly going long.
overall i expect to go short on gbpusd
