Trading is buying and selling financial assets, such as stocks, currencies, futures or crypto, with the goal of profiting from changes in their price. A trader buys something they expect to rise and sells it later for more, or sells something they expect to fall and buys it back for less. The time between the two can be seconds, days or months.

That one sentence hides most of what matters. Every trade has someone on the other side. Every price is the result of millions of decisions. And every profit has a matching risk. This lesson explains how trading actually works before you learn any technique.

## The basic idea: a trade has two sides

When you buy 10 shares of a company, someone else sells you those 10 shares at the same moment and at the same price. You think the price will go up. They either think it will go down, need the cash, are rebalancing a fund, or are a [[market-makers|market maker]] who simply earns a small fee for being available. You do not need to know who they are, but it helps to remember that the market is not a machine that pays out. It is other people and institutions, many of them well informed.

A complete trade has an entry and an exit:

- **Entry:** you open a position by buying (going long) or by selling something you do not own (going short).
- **Exit:** you close the position by doing the opposite.
- **Result:** the difference between the two prices, multiplied by the size of the position, minus costs such as commissions and the [Bid-Ask Spread](https://learn.tradelabsai.com/markets/bid-ask-spread/).

**Example: A simple long trade**
You buy 20 shares at $50.00, a $1,000 position. A week later you sell them at $54.00 for $1,080. Your gross profit is $80, or 8%. If you paid $1 in commission each way and lost about $0.40 to the spread, your net profit is about $77.60. Had the price fallen to $46.00 instead, you would have lost $80 plus the same costs.

## What gets traded

Most of the world's trading happens in a handful of markets. Each one has its own lesson later in the school, but here is the map:

| Market | What you trade | Typical participants |
|---|---|---|
| Stocks | Shares of ownership in companies | Individuals, funds, pensions |
| Forex | One currency against another, such as EUR/USD | Banks, companies, speculators |
| Futures | Contracts to buy or sell something at a set future date | Producers, hedgers, funds |
| Options | The right, not the obligation, to buy or sell at a set price | Hedgers, income traders, speculators |
| Crypto | Bitcoin, Ether and other digital assets | Individuals, funds, market makers |
| Prediction markets | Shares that pay $1 if an event happens | Forecasters, traders |

Start with [What Is a Stock?](https://learn.tradelabsai.com/markets/what-is-a-stock/) if you are completely new, because stocks are the easiest market to picture: a share is a small piece of a real business.

## Why prices move

Prices move because the balance between buyers and sellers changes. If more people want to buy at the current price than want to sell, buyers must offer more, and the price rises. If sellers are more eager, the price falls. Everything else is a reason for that balance to shift:

- **News and data:** earnings reports, interest rate decisions, inflation numbers, product launches, lawsuits.
- **Expectations:** markets move on what people think will happen, so a good result can still push a price down if traders expected even better.
- **Flows:** large funds buying or selling for reasons unrelated to value, such as index changes or redemptions.
- **Positioning and emotion:** crowded trades unwinding, fear in a sell off, greed in a rally.

You will not know every reason. Traders accept this and focus on what they can measure: price, [Volume](https://learn.tradelabsai.com/markets/volume/), [Volatility](https://learn.tradelabsai.com/markets/volatility/) and their own risk.

## Trading is not the same as investing

Investors buy assets to hold for years and benefit from the growth of the business or economy. Traders hold for shorter periods and try to profit from price movement itself. Both are legitimate, and many people do some of each. The differences in time, effort, cost and risk are big enough that they get their own lesson: [Investing vs Trading](https://learn.tradelabsai.com/start-here/investing-vs-trading/).

## The main styles of trading

Traders are usually grouped by how long they hold a position:

- **Scalping:** seconds to minutes, many small trades.
- **Day trading:** opening and closing within the same day, never holding overnight.
- **Swing trading:** holding for a few days to a few weeks to catch one move.
- **Position trading:** holding for weeks or months based on bigger trends.

Shorter styles need more screen time, faster decisions and lower costs per trade. In the United States, people who day trade stocks in a margin account also run into FINRA's [pattern day trader rule](https://www.finra.org/investors/learn-to-invest/advanced-investing/day-trading-margin-requirements-know-rules), which has long required at least $25,000 in the account once you make four or more day trades in five business days. Check the current version of the rule with your broker, because FINRA has proposed changes to it.

## The honest part: risk

Most people who start trading lose money, especially in short term and leveraged trading. Brokers that offer CFDs in Europe are required to publish the share of their retail accounts that lose money, and the figures are usually well above half. The reasons are consistent: costs add up, losses are cut too late, position sizes are too large, and emotions take over after a loss.

None of that means trading is impossible. It means the first skill is not finding winning trades. It is surviving long enough to learn, by keeping each loss small. That is why this school puts [Position Sizing](https://learn.tradelabsai.com/risk/position-sizing/) and the [Risk/Reward Ratio](https://learn.tradelabsai.com/risk/risk-reward-ratio/) early, and why we suggest starting with [Paper Trading](https://learn.tradelabsai.com/start-here/paper-trading/), which lets you practice with simulated money. TradeLabs AI has a free [paper trading](https://tradelabsai.com/paper-trading) mode if you want to try your first trades without risking anything.

**Watch out: Never trade money you cannot afford to lose**
Leverage, margin and derivatives can lose more than your starting balance. Learn how they work before you use them.

## What a trader actually does all day

Successful traders spend far less time clicking buy and sell than people imagine. Most of the work is preparation and review:

1. **Plan:** decide which markets you trade, what setups you look for and how much you risk per trade. See [Building a Trading Plan](https://learn.tradelabsai.com/start-here/building-a-trading-plan/).
2. **Wait:** most of the time there is nothing worth doing. Not trading is a decision.
3. **Execute:** enter with a defined exit for both the good case and the bad case, using the right [[order-types-explained|order types]].
4. **Review:** record every trade in a [Trading Journal](https://learn.tradelabsai.com/start-here/trading-journal/) and look for patterns in your mistakes.

## Frequently asked questions

### Is trading the same as gambling?

No, but it can turn into gambling. Trading with a tested plan, defined risk on every trade and records of your results is a skill you can measure. Trading on impulse, without an exit plan or with money you cannot afford to lose, behaves much like gambling and usually ends the same way.

### How much money do I need to start trading?

You can practice with no money at all through paper trading. To trade real stocks, many brokers have no minimum and offer fractional shares, so you can start with a small amount. In the United States, day trading stocks in a margin account has long required $25,000 under the pattern day trader rule.

### Can you make a living from trading?

Some people do, but it is rare and usually takes years. Most beginners lose money at first. A sensible goal for your first year is to learn, keep losses small and build a record of trades you can study, not to replace your income.

### What is the easiest market to start trading?

Large company stocks and broad ETFs are the easiest to understand and usually have low costs and tight spreads. Leveraged products such as futures, CFDs and options move faster and can lose more than you put in, so they are better learned later.
