Online Currency Trading Reviews

Can anyone please explain what it means to buy and sell on forex?
I am little confuse about the buying and selling on forex.
for example, If i think that a currency is going to increase after reviewing the market trend, well lets use the EUR/USD for example. If i think that graph is going to go up, do i buy that currency or do i sell that currency.
Thanks for your answers, I am using a practice account and do plan to start a real one as soon as I can fully understand the basics of trading, which is something I am totally new to and see as a great way to make some money online.
Your goal is to buy low and sell high, so, if you think that a currency is going to go up in value you buy and then sell when it’s gone up, the difference in value is your profit.
It’s smart to use a practice account for a while. Never use a live account until you’ve acquired the necessary skills. A lot of people skip this part, end up losing money, quit and never realize the benefits and lifestyle that being a forex trader can bring to their life.
Good luck to you
