Hey there I hope you are correct, and yes the golden cross is a bullish signal for sure, although I am ot sure about which EMAs cross upward over the other. I would say that since it is the weekly chart, then even the 21 period crossing up above the 50 period woudl be a clear signal. On the smaller time frames, it might require that the 50 or 100 daily cross up over the 200 daily EMA for example.
