Here are my suggestions:
Pay off any high interest debt first, like credit card debt.
Then put some money aside for emergencies.
Put aside more money, like 6 months living expenses worth.
After these, if you have a mortgage, you might consider paying extra each month to pay it off quicker and save on interest payments.
After these, you might start thinking about "investing".
Playing with stocks, especially forex, is just gambling. If you want to go that route, just know full well that you are gambling with your hard earned money.
If you want to get started investing instead, start looking into buying index funds first.
Then read about how to invest in companies if you really want to dip into buying individual companies
Good luck
