Server
The server settings for MetaTrader 5 are shown below. A trader can edit from this tab, but most of the times it is not necessary as these options are automatically preset to the brokers' server settings by the broker and there is no need to re-adjust them. However, just for tutorial purposes, the Server will show the server of your xauusd broker and if it is a Demo or a Real Server. The MT5 account login & password will also be displayed below and as a trader you can change the password from this window for demo xauusd accounts, however be careful if you are changing passwords make sure to remember them.

Other options are, enable proxy server, this is not required, Keep personal data at startup, this is ticked by default, that way the trading platform will automatically remember your login & password so that you do not have to type them and key them in every time you sign in to your platform. Enable DDE server is not required, Enable the news is ticked and you can receive real time news reports to your MetaTrader 5 on News options, located in the Terminal window, (Shortcut Keys Ctrl+T).
XAUUSD Chart

The following are marked on Charts Options
Show Trade Levels - These lines will show levels where orders were placed, it will also show levels where pending xauusd orders are placed. This will also show the Take Profit Gold Order & Stop Loss XAUUSD Order areas. These trade zones lines appear as red broken lines marking these trade levels.
If there is no open transaction, no level will be shown: if many gold trades have been placed, multiple lines will be displayed for these levels.
Use Alt key to drag trade levels isn't a very suitable option to use, because if you place many orders you might change wrong order, therefore it is best to leave this as it's & not change it (Probability of this one losing you money is there so leave as it is)
Show OHCL - Show Opening, High, Closing and Low XAUUSD Prices for every candle
Show Ask Line - Show the Bid XAUUSD Price, (no need for this)
