Gold Analysis on weekly chart and expecting next moves

this is the weekly chart and u can see it is forming head and shoulders, however there is resistance at 1870 because of "left shoulder" but the retracement(our current short uptrend) haven't hit the 50%fib level yet. i expect it next week to go up till 1892 and hit the 50% fib level and then drop right back below 1870 so the weekly candle doesnt close above the resistance level and continue the downtrend.

I am not a professional trader and this is only my insight
