Just similar to the steps that you have to follow before entering any new business, first of all you have to start with learning the skill set required for trading, this should include technical analysis, risk management and wealth creation. Apart from these get yourself familiarised with the environment using paper trading or mock trading and then start with a small capital which you can afford to lose. Connect with other traders and learn from them don't copy their strategies as it is but inculcate something from their strategy into your trading. Also learn emotional control which is the most important thing in all this.
