I am new here. So I need some help from veteran traders could you please tell me how could I trade here safely

Google search is the key.
All you have to do is to read references about:
-beginner in trading
-trading basics
-how to trade
-important things to take note of in trading and any related stuff
There is no one who will provide you a one-on-one tutorial since all help can be found now on the internet. It's free and all information almost spoonfed to us.
