How Does Trading Actually Work? A Beginner's Walkthrough

Now that you know what a broker is, what a platform looks like, and what markets exist, let's walk through what actually happens when you "make a trade."

At its core, trading means predicting whether the price of something will go up or down, and opening a position based on that prediction. If you think the price will rise, you "buy" — this is also called "going long." If you think the price will fall, you "sell" — this is also called "going short." Unlike traditional investing, trading lets you potentially profit even when prices are falling, because you can sell first and buy back later at a lower price.

Once you open a trade, it's called an "open position." While it's open, its value moves up and down in real time along with the market price. You decide when to close it — and whenever you do, the difference between your entry price and your exit price becomes your profit or your loss.

A few terms you'll see constantly: "lot size" refers to how much of something you're trading — the bigger the lot size, the bigger your profit or loss for the same price movement. "Leverage" lets you control a larger position than the money in your account would normally allow, which can multiply both profits and losses, so it must be used carefully.

For a first trade, the process looks like this: open your platform, pick an instrument (say, a currency pair), decide buy or sell based on your prediction, choose how much to trade, click the order button, and watch your open position. When you're ready, click close to end the trade and see your result.

This is why practicing on a demo account first matters so much — it lets you go through this entire process, make mistakes, and learn the mechanics before any real money is involved.
