There's many versions of this sort of thing around the Tradingview library, but i guess we all like things to our own specifications.
So this is my take on the SMA and EMA version combined.
Bunch of SMA's & EMA's, with labels, and G&D Cross Labels and Alerts.
These values can of course be changed to any you may prefer.

The Golden Cross is one of the simplest market indicator who helps long term investors to entry a position.
With that in mind, I made a very easy to understand backtest showing how much we could earn if we entered in a Golden Cross and exit when Death Cross happening.
Take this code and try in your favorite market.
Of course, never use only this indicator to trade.
