First need to get a demo account and learn how to trade it. They come up with free virtual funds and real market conditions of price so we can practice real time and if we lose we don't lose anything yet we can identify our mistakes.
I'd recommend that you pick the pair you would like to trade and follow up with the economy and news releases related to that pair. This will give you a heads-up and give you some time to prepare before the news is out. Not to forget, geopolitics can also affect the pair depending on which pair you are trading.
