Hi Ariel,
Yes, water is your favorable element. And in your chart, because of the absence of Yin (Gui) Water. Your Useful God star is the Yang (Ren) Water. Metal is secondary favorable element.
Your career should be related to Water, Metal or both elements.
As to weather you should be in real estate or the stock market. You should be in the latter. BUT not without proper education and research. Because otherwise you will be 'speculating' and if so, this is not part of your chart to get lucky through windfall gains.
Warm Regards,
JY
