Start with opening an order and see what happens when you buy or sell trading pair. Is the market moving your way or you have made wrong decision.
That way you will learn how trading works.
From there you can start reading more or find a mentor so you learn next steps in your trading journey.
That should be understanding pips, leverage, lot size, trend lines, support and resistance lines.
Before going to live account you need to make a trading strategy which will guide you when and under which conditions you will open a trade.
After the trade is open and closed you need to make a journal to record your trades. That base of knowledge will serve you as a pool of valuable informations what you have done correct and where you have made mistake.
Expect to jump over some of the above steps but when you lose some or a lot of money you will get back to those stepyls and try to become profitable trader. :).
It is hard to tell someone to do something because we people tend to learn on our mistakes instead learning from others. I have done same mistakes but hey :). I am human.
Best of luck.
