Trading is buying and selling financial assets, such as currencies, stocks, gold or crypto, with the aim of profiting from changes in their price. A trader buys when they expect a price to rise or sells when they expect it to fall, then closes the position to lock in the result, whether that is a gain or a loss.
Trading differs from investing mainly in time horizon. An investor typically buys an asset to own it for years. A trader holds positions for minutes, days or weeks and cares less about owning the asset than about the price move itself.
This guide covers who trades, the main markets, how prices move, trading styles, analysis approaches and why risk comes first.
Who trades and why
Markets bring together participants with very different goals, and knowing who is on the other side helps explain how prices behave.
- Banks and dealers quote prices to clients and trade large amounts of currencies, bonds and other assets every day.
- Funds and asset managers invest on behalf of savers, often splitting large orders over hours or days.
- Companies hedge, for example an exporter locking in today's exchange rate for dollars it will receive in six months.
- Market makers stand ready to buy and sell at all times and earn the small gap between their buying and selling prices.
- Retail traders are individuals trading through online platforms, with their own money or through a prop firm evaluation.
Not everyone trades to profit from the price itself, and that mix of motives and time horizons is part of what keeps prices moving.
The main markets you can trade
Stocks
A share of stock is a small piece of ownership in a company. Stock prices react to earnings, economic news and market mood. Stock indices, which track a basket of large companies, are also widely traded.
Forex
The foreign exchange (forex) market is where currencies are exchanged. Currencies are quoted in pairs, such as EUR/USD, because every currency trade swaps one currency for another. Forex is the largest financial market in the world and trades around the clock from Monday to Friday.
Commodities
Commodities are physical goods such as gold, silver, oil and wheat. Gold, quoted as XAU/USD, is one of the most actively traded, partly because many participants treat it as a store of value in uncertain times.
Crypto
Cryptocurrencies such as Bitcoin (BTC) and Ether (ETH) are digital assets. Unlike most traditional markets, crypto trades every day of the week, and its prices tend to move more sharply.
Many traders never buy the underlying asset at all. They trade contracts that track its price, such as futures. The guide on forex vs futures vs spot trading explains how these products differ.
Buying and selling short
When you buy first, hoping to sell later at a higher price, you are going long. When you sell first, hoping to buy back later at a lower price, you are going short. Your profit or loss is the difference between your opening and closing prices, multiplied by your position size.
With stocks, selling short usually means borrowing shares to sell; with contracts such as forex and futures, you simply open a sell position.
Worked example: a long and a short
For example, say you buy EUR/USD at 1.0850 with a position of 10,000 euros (a mini lot) and later close it at 1.0900.
- Price change: 1.0900 − 1.0850 = 0.0050, or 50 pips
- Profit: 10,000 × 0.0050 = $50
A pip is the standard unit of price movement in forex, 0.0001 for most pairs. The guide to pips, lots and leverage covers pips and position sizes in detail.
Now a short. Say you sell 0.1 BTC at $65,000 because you expect the price to fall, then buy it back at $63,000.
- Price change in your favor: $65,000 − $63,000 = $2,000 per BTC
- Profit: 0.1 × $2,000 = $200
If Bitcoin had instead risen to $67,000, the same short would have lost 0.1 × $2,000 = $200. A price can only fall to zero, but it has no ceiling, so a short has no natural limit on how much it can lose. That is one reason every trade needs a planned exit.
How prices move
Prices move because of supply and demand. When more traders want to buy than sell at the current price, buyers have to pay more to get filled, and the price rises. When sellers are more eager, the price falls. News, economic data, interest rate decisions and shifts in sentiment all change that balance, sometimes within seconds.
At any moment a market shows two prices: the bid, at which you can sell, and the ask, at which you can buy. The small gap between them is the spread, explained in bid, ask and spread.
A market with many buyers and sellers is called liquid. Liquid markets usually have smaller spreads and move more smoothly, while thin markets can jump from one price to the next.
Timeframes and trading styles
A trading style is mostly defined by how long you hold positions.
| Style | Typical holding time | What it involves |
|---|---|---|
| Scalping | Seconds to minutes | Many small trades aiming for small moves; costs and focus matter most |
| Day trading | Minutes to hours | Positions opened and closed within the same day |
| Swing trading | Days to a few weeks | Aims to capture one larger move, or swing, in price |
| Position trading | Weeks to months | Follows longer trends with fewer trades and wider stops |
Shorter styles demand more screen time, and costs take a bigger share of each small gain. Longer styles need patience to sit through larger swings against you. No style is better in itself; the right one fits your schedule and is one you can follow consistently.
Chart timeframes follow the style, from one-minute charts for scalping to daily and weekly charts for position trading. Many traders use a higher timeframe for direction and a lower one to time entries.
Technical and fundamental analysis
There are two broad ways to analyze a market, and many traders combine them.
Technical analysis studies price itself: charts, trends, support and resistance levels, chart patterns and indicators such as moving averages or the Relative Strength Index (RSI). The idea is that price behavior shows recurring patterns that can help frame a trade.
Fundamental analysis studies what drives value: interest rates, inflation, employment and central bank policy for currencies, earnings for stocks, and the US dollar and interest rates for gold. Fundamental traders ask why a price should move; technical traders focus more on when and where.
Neither approach predicts the future; both are ways to build a plan with a defined entry, exit and risk.
Risk: the skill that matters most
Every trade can lose. What separates traders who last from those who don't is usually not a cleverer entry; it is how much they lose when they are wrong.
Managing risk means deciding, before you enter, where you will exit if you are wrong and what that exit will cost. Many traders limit the risk on each trade to a small, fixed percentage of their account.
Risk per trade = account balance × risk percentage
For example, on a $10,000 account, risking 1% per trade means a maximum planned loss of $10,000 × 0.01 = $100. Ten losing trades in a row would cost at most $1,000, or 10% of the account. At 10% per trade, the same streak would cost about 65% of the account even if you sized each trade from the shrinking balance, because 0.9 multiplied by itself ten times is about 0.35.
If you trade a prop firm evaluation, risk control is also what keeps you within its limits; prop firms usually set a daily loss limit and an overall drawdown limit. The guide on how to measure risk in trading shows how to apply this on every trade.
Common mistakes
- Entering without an exit plan. Fix: decide your stop level and the dollar amount at risk before you place the trade.
- Trading larger because leverage allows it. Leverage lets you control a position larger than the cash you put up. Fix: size each trade from your planned loss, not from the maximum the platform allows.
- Jumping between markets and styles. Fix: pick one or two markets and one style, and learn how they behave before adding more.
- Treating a few wins as proof. Fix: judge a method over a large sample of trades recorded in a journal, with costs included.
Key takeaways
- Trading is buying and selling assets to profit from price changes, usually over shorter periods than investing.
- The main markets for beginners are stocks, forex, commodities such as gold, and crypto.
- You can aim to profit from rising prices by going long and from falling prices by going short; both can lose.
- Prices move with supply and demand, and every market has a bid, an ask and a spread.
- Your style, from scalping to position trading, should fit your schedule and temperament.
- Risk management, not prediction, is the core trading skill.
Frequently asked questions
Is trading the same as investing?
No. Investing usually means buying assets to hold for years for long-term growth or income. Trading means holding positions for shorter periods to profit from price changes in either direction, with a close focus on the risk of each trade.
How much money do I need to start trading?
Many platforms let you open small positions, such as micro lots in forex or fractions of a coin in crypto, so the minimum can be low. The more important question is how much you can afford to lose. Many beginners first practice on a demo account, which uses virtual money, to learn the platform and test a plan.
Can you lose more than you put in?
It depends on the product and the provider. With leveraged products, a sharp move or a price gap can produce a loss larger than the margin you put up, and not every provider protects retail clients from a negative balance. Check how your platform handles this before you use leverage.
What should a beginner learn first?
Start with how the main products work in forex vs futures vs spot trading. Then learn the units of a trade in pips, lots and leverage and what each trade costs in bid, ask and spread. Finally, work through how to measure risk in trading so every position has a defined, affordable loss.
