What is trading?

Trading is buying and selling financial assets, such as currencies, shares, gold or stock indices, to try to gain from changes in their price. Traders hold positions for minutes, hours, days or weeks, not years. They can aim to gain when prices rise or fall, and they pay a cost on every trade.

This lesson opens Market Basics, the first module of this academy, which teaches trading.

Key terms

• Capital: the money you commit to the market.
• Position: an open trade or holding. It stays open until you close or sell it.
• Time horizon: how long you plan to stay in a position or keep money invested. The US Securities and Exchange Commission's investor site, Investor.gov, defines it as the number of months, years or decades you plan to invest to reach a goal.
• Leverage: using a small deposit to control a bigger position. It magnifies gains and losses.

How does trading work?

Every trade has two steps: you open a position, then you close it, and the difference between the two prices is your profit or loss. You choose a direction when you open. Your profit or loss is the price change multiplied by the size of the position, minus the cost of the trade.

• Buy (go long) if you expect the price to rise. You gain if you later close at a higher price.
• Sell (go short) if you expect the price to fall. The SEC explains that short sellers buy the stock at the lower price and make a profit if the price drops. With CFDs, you can sell first without owning the asset.

Profit or loss = (closing price − opening price) × number of units, with the sign flipped for a short. Using synthetic figures, before costs:

Every trade also has a cost, paid whether it wins or loses. For CFDs these costs include bid-offer spreads, daily and overnight financing costs and commissions. Costs are covered in spread, commission and swap, and direction in going long and short.

What can you trade?

You can trade any asset with a price that moves, and most retail traders start with currencies, stock indices, commodities and company shares. Each group is called an asset class, and each trades at different hours and is moved by different news:

• Forex: currency pairs, such as EUR/USD or USD/JPY.
• Indices: a basket of shares tracked as one price, such as the US 500.
• Commodities: gold, silver and oil, among others.
• Shares: individual companies listed on a stock exchange.

Many retail traders trade these through CFDs rather than buying the asset itself. Each asset class is covered in trading asset classes.

What are the main types of trading?

Trading styles are grouped by how long a position stays open, from seconds to months. Shorter styles mean more decisions, more trades and more costs. Scalpers and day traders close positions within the day, while swing and position traders hold overnight and pay financing on leveraged positions.

Scalping and day trading take the most screen time, because positions need watching while they are open. Swing and position trading fit around a job, with decisions made a few times a week or month.

CFDs, or contracts for difference, are explained in what is a CFD.

What is the difference between trading and investing?

The difference between trading and investing is how long you hold, and why. An investor buys an asset, such as a company's shares, and holds it for years, hoping its value grows. A trader opens and closes positions over minutes, days or weeks, trying to gain from shorter price moves.

Think of running. Investing is a marathon: slow and steady over a long distance. Trading is a series of sprints: short, fast, and every second counts.

What is investing?

Investing is buying an asset and holding it for a long time, often years, in the hope that its value grows. Investors usually buy shares, bonds or funds and pay the full price. They make fewer decisions and focus on the long-term value of what they own, not on daily price swings.

When you buy a share, you buy a piece of ownership in a company. Investor.gov explains that all investments involve some degree of risk. A company can fail, and even healthy companies' share prices move up and down.

What are the main investing styles?

The main investing styles are value investing, buying assets that look cheap against their earnings or assets; growth investing, buying companies whose earnings are rising fast; dividend investing, buying for regular income; and index or buy-and-hold investing, owning a whole market through a fund for decades. All four hold for years.

The trading styles above, from scalping to position trading, are the short-term counterparts: they look for gains within minutes to months instead of years.

How do trading and investing compare?

Trading and investing differ on almost every practical point: how long you hold, how you hope to gain, what you buy, how you analyse it, what it costs, whether leverage is used, how much time it takes and how fast results build. The table sets them side by side.

CFDs are built for trading price moves over minutes, hours or days, so traders watch an open CFD position more closely than a long-term investment.

Two terms from the table:

• Technical analysis: studying past price movements on charts to judge where the price may go next. Reading charts is covered in Module 4, Reading Price Charts.
• Fundamental analysis: judging what an asset is worth from the facts behind it, such as a company's earnings or a country's economy.

Trader vs investor: which one are you?

Whether you are a trader or an investor depends on your goal, the time you can give and how you handle falls in value. If you want to act on price moves of minutes to weeks and can give regular hours, you are a trader; if you want growth over years with periodic reviews, you are an investor.

These questions help you see which one fits your situation before you put any money in.

Many people do both: long-term savings invested for years, and a separate trading balance on MetaTrader 5 that they size every trade from. If you answered mostly in the trading column, the rest of this course takes you from your first chart to your first trade.

How does one price move affect a trader and an investor?

The same price move gives the same profit or loss per unit, but leverage changes how big that result is compared with the money you put down, and trading costs add up with every trade. The figures below are synthetic.

Company A's share trades at $100. Two people each take a position on 10 units, worth $1,000.

• The investor buys 10 shares outright and pays the full $1,000.
• The trader opens a CFD on 10 units. Suppose the margin needed is 20% of the position (5:1 leverage), so $200 is set aside.

Profit or loss = (closing price − opening price) × number of units. The price change is identical for both. What differs is the share of their own money it represents. A 15% fall costs the investor 15% of their money. It costs the trader 75% of theirs.

Now add costs. Suppose each round trip, opening and closing a trade, costs $3 in spread and commission. The investor buys once: $3. The trader who trades thirty times in the year pays $90, whether the trades win or lose. More trades means more cost, so every trade needs a reason strong enough to cover it.

To see how much margin a position needs at different leverage, try the margin calculator. Leverage itself is covered in leverage and margin.

What are the risks of trading and investing?

The main risk of investing is a long fall in value, and the main risks of trading are leverage, costs that grow with activity and the pace of decisions. An investment can take years to recover from a fall. A trade moves faster, so traders set their risk up front with position size and a stop loss on every trade.

Risks of investing:

• Prices fall and stay down. Investor.gov notes that large company stocks as a group have lost money on average about one in every three years.
• Business risk. If a company fails, its shareholders are last in line and may get nothing back.

Risks of trading:

• Leverage. A small move is a large share of your deposit, in either direction. Position size is the control.
• Costs. Every trade costs money, and overnight financing applies to leveraged positions held open.
• Pace. Short time frames mean frequent decisions. A written plan with entry, stop and size for each trade keeps them consistent.

Managing these risks, through position size and stop losses, is the subject of Module 5, Risk Management.

Try it on demo

In MetaTrader 5, open a demo account and pick one instrument from Market Watch. Open its chart on the M5 (5-minute) timeframe, then switch to D1 (daily) using the timeframe buttons on the toolbar. Notice how jumpy the 5-minute chart is next to the calmer daily one. That is the view of a trader compared with the view of an investor.

Next in Market Basics: the main markets you can trade, in trading asset classes.

Is trading riskier than investing?

Trading moves faster than investing, because of leverage, frequent costs and short time frames, so results build quicker in both directions. Investing has its own risk: prices can fall and stay down for years, and a company can fail. Traders manage their pace with position size and stop losses.

Can you do both trading and investing?

Yes. Some people hold long-term investments and trade a separate, smaller amount of money.

What is trading in simple words?

Trading means buying something and selling it later, or selling first and buying back later, to try to gain from the change in price. In financial markets, that something is a currency, share, index or commodity.

Is forex trading or investing?

Forex is usually traded rather than invested in. Retail forex is mostly short-term, leveraged and often offered as CFDs, where you take a position on an exchange rate without owning the currency.

Which is better for beginners, trading or investing?

It depends on your goal. Investing suits growing savings over years with few decisions. Trading suits people who want to act on short-term price moves and can give it regular time. If you choose trading, start on a demo account and learn risk management before using real money.
