What is trading?

You see someone looking at a chart.

Numbers are changing. Lines are moving. They click a button, and a few minutes later they say they made money.

What actually happened?

What did they buy? Who did they buy it from? And how did a change on a screen become money?

Before we talk about strategies, indicators, or when to enter a trade, we need to understand the activity itself.

Let’s start there.

A simple exchange

Imagine you buy a collectible card for twenty dollars.

Later, someone is willing to pay you twenty-five dollars for it. You sell it.

You paid twenty dollars and received twenty-five. The difference is five dollars.

That’s a five-dollar profit, before any costs involved in buying or selling.

Now imagine the opposite happens.

You pay twenty dollars, but the best offer you can find later is fifteen. If you sell at that price, you lose five dollars.

Same card. Same person. Different outcome.

You might have believed the card would become more valuable. But believing something doesn’t mean another person will pay the price you want.

Keep that idea in mind.

In financial markets, people buy and sell things such as shares in companies, currencies, and contracts.

The details differ, but the basic activity involves exchanging something at an agreed price.

When people talk about trading as a way to make money, they usually mean taking positions with the aim of benefiting from changes in price.

We’ll explain “positions” in a moment.

Trading is a broad word

Saying “I want to start trading” is a little like saying “I want to play sports.”

It tells us you’re interested, but it leaves a lot unanswered.

Basketball, swimming, and boxing are all sports. Knowing the rules of one doesn’t mean you understand the others.

Trading is similar.

Stocks, currencies, options, and futures all fall under the trading conversation. But what you’re buying or selling—and the rules and risks involved—can be very different.

For example, a share of stock represents a small ownership interest in a company.

A futures contract is a different kind of financial instrument. Buying one isn’t the same as buying a piece of a company.

So the first question is:

What market am I talking about, and what would I actually be trading?

In this video, we’re starting with trading itself.

In the next lesson, we’ll explore futures as one type of market you can trade.

What is a market?

A market brings buyers and sellers together.

Think back to the collectible card.

You want to sell it for twenty-five dollars. Someone else is willing to pay twenty-two.

You have an asking price. They have an offer.

A transaction can happen when a buyer and seller agree on a price.

Financial markets organize that activity on a much larger scale. Orders communicate what participants want to buy or sell, how much, and sometimes the price they’re willing to accept.

A chart records price activity over time.

That’s what those moving lines and candles are helping you see.

But a chart doesn’t tell you what must happen next.

It shows what has happened. Traders use that information, along with other information, to make decisions about an uncertain future.

What is a trade?

Let’s use a simple stock example.

Suppose you buy one share for fifty dollars.

You now have an open position. In this example, that means you own the share and are exposed to changes in its price.

If its market price rises to fifty-five dollars, your position has increased in value by five dollars.

If you sell at fifty-five, you close the position and realize that five-dollar gain, before costs.

If you sell at forty-five, you realize a five-dollar loss.

Buying opened the position. Selling closed it.

While the position was open, its value could change.

That helps explain something you’ll hear traders say: “I’m up,” or “I’m down.”

They may be describing a position they still hold. That result can change before they close it.

Also, buying first and selling later is only one way a trade can work.

Some markets allow traders to take positions that benefit when prices fall. That’s called going short.

The mechanics depend on the instrument. We’ll explain them properly when we get to futures.

For now, understand that trading can involve expectations about either rising or falling prices.

Why do prices move?

People don’t all agree about what something is worth.

They also don’t all have the same reason for buying or selling.

One participant may respond to news. Another may need to reduce risk. Another may be closing a position they opened earlier.

As orders interact, transactions can occur at different prices.

Those transactions become part of the price activity you see on a chart.

The important point is that the market includes many participants making decisions for different reasons.

Your expectation is one expectation among them.

The price doesn’t have to move in the direction you want.

Where does a trader’s profit come from?

In our simple example, the profit came from selling at a higher price than the purchase price.

But there’s another detail.

Buying and selling can involve costs. Those costs reduce a gain or increase a loss.

So a favorable price change and a profitable trade aren’t always exactly the same thing.

And one profitable trade doesn’t establish that someone has a reliable way of trading.

A decision can work once and fail when repeated.

Someone can also make a reasonable decision and still lose on a particular trade.

That’s why evaluating trading means looking beyond one screenshot or one outcome.

We need to understand the decisions, the risks, the costs, and what happens over repeated attempts.

Those are questions we’ll return to throughout this channel.

Trading and investing

You’ll also hear people distinguish trading from investing.

There’s overlap, and there isn’t one universal time limit separating them.

Generally, investing emphasizes holding assets to benefit from their value or income over time.

Trading tends to emphasize buying and selling to benefit from price changes over a chosen period.

That period might be minutes, days, or longer.

Both involve uncertainty. Calling an activity “investing” doesn’t automatically make it safe, and calling it “trading” doesn’t tell us how responsibly it’s being done.

We still need to inspect the actual decisions.

What you should understand now

Trading involves buying and selling financial instruments.

A position exposes you to changes in value. Depending on the instrument and the direction of the position, those changes can produce gains or losses.

The market brings participants together, and a chart helps display its price activity.

But seeing a chart is different from understanding what you’re trading.

Before learning a strategy, you need to understand the instrument and how its mechanics affect your money.

That brings us to the next question:

What exactly are futures—and what are futures contracts?

In the next lesson, we’ll unpack both terms: what people mean when they talk about trading futures, what a futures contract represents, why these markets exist, and what traders are actually buying or selling.
