What Is Trading? Beginner's Guide to Financial Markets

What Trading Actually Is

Trading is the buying and selling of financial instruments with the goal of profiting from price changes. You buy something you think will rise. You sell something you think will fall. If that second one still sounds backwards, hold on — short selling is one of those concepts that sounds wrong until it suddenly clicks, usually around the time you first get it wrong on a live account.

The “something” can be a currency pair, a share in a company, a commodity like gold or oil, or a derivative that tracks the price of any of those things. The profit comes from the gap between your entry price and your exit price — minus whatever fees your broker collects along the way. Brokers are reliably good at collecting fees.

What trading is not: a guaranteed income, a get-rich shortcut, or a hobby that pays for itself on a £500 account. It is a skill that takes years to build and a process that takes discipline to maintain. My apprentice groans every time I say that — he wanted the short version. Unfortunately, the short version leads to margin calls.

The key thing separating trading from general commerce is that traders are not interested in using what they buy. A trader who buys euros doesn't want euros. They want the price of euros to move so they can sell at a profit. The asset is irrelevant. The price movement is the entire game.

How Trading Works

At its most mechanical level, trading works through supply and demand. When more people want to buy an asset than sell it, the price rises. When more want to sell, it falls. Every price you see on a chart is simply the most recent agreement between a buyer and a seller on what that asset is worth right now.

In practice, retail traders access markets through a broker. The broker provides a platform, a price feed, and the ability to open and close positions. When you go long, you're betting the price will rise — you profit if it does. When you go short, you're betting it will fall — you profit if it does, and you lose money if it rises instead.

Most retail traders use contracts for difference (CFDs), which let you take a position on price movement without owning the underlying asset. CFDs come with leverage — which means you can control a large position with a smaller amount of capital. That amplifies gains when you're right. It also amplifies losses when you're wrong, which is why regulators like the FCA require brokers to display CFD loss rates prominently. The average is not flattering.

Every trade has two components: the entry (where you open) and the exit (where you close). The difference between them — after fees — is your profit or loss. The difficulty is not understanding the mechanics. It's knowing when to enter, how long to hold, and — most importantly — when to accept that the trade isn't working and close it. Jaws is a film about refusing to leave the water when the evidence suggests you should. It does not end well for the swimmers.

For a detailed look at how this plays out in the currency markets, the professional forex trading framework guide covers the full pre-trade process from analysis through to execution.

The Main Types of Trading

There is not one way to trade. Different styles suit different personalities, schedules, and risk tolerances. Here are the four most common.

Day trading

Day traders open and close all positions within the same trading day, finishing with no open trades overnight. The advantage: you're never exposed to gaps — price jumps that happen when the market is closed. The disadvantage: it requires your full attention during market hours and creates psychological pressure that most beginners severely underestimate. For a full breakdown of what this looks like in the forex context, the honest guide to day trading forex covers the costs, the sessions, and five strategies that actually have an edge.

Swing trading

Swing traders hold positions for days to weeks, targeting medium-term price moves. This style suits people who have a job and can't watch a screen all day. You check your positions in the morning, adjust if necessary, and get on with your life — which is a more sustainable arrangement than staring at the EUR/USD on a 5-minute chart for six consecutive hours. The forex swing trading strategies that actually work covers the specific approaches with a documented edge.

Position trading

Position traders hold for weeks to months and base decisions heavily on fundamentals — economic data, interest rate differentials, geopolitical shifts. This is the style closest to investing in time horizon. It requires patience that most people dramatically overestimate their ability to maintain, especially when a position moves against them in week two.

Scalping

Scalpers make many small trades in rapid succession, targeting tiny price movements — sometimes just a few pips at a time. It requires low-latency execution, tight spreads, and a tolerance for repetition that is genuinely uncommon. My apprentice tried scalping for two weeks and described the experience as “doing maths on a rollercoaster.” He was not wrong. He also stopped.

What You Can Actually Trade

Financial markets cover a wide range of asset classes. The main ones retail traders access:

• Forex (foreign exchange): the largest financial market in the world, with daily turnover of around $7.5 trillion according to the 2022 BIS Triennial Survey. You trade currency pairs: EUR/USD, GBP/JPY, AUD/CAD. One side goes up; the other goes down. The market does not take breaks.
• Stocks and shares: equity in individual companies. Price movements are driven by earnings, economic data, news events, and sentiment — sometimes in that order, sometimes in no order at all.
• Indices: baskets of stocks tracked as a single instrument — the FTSE 100, S&P 500, DAX. Trading an index gives you broad market exposure without picking individual companies. You're betting on the general direction of an economy, which is difficult but at least slightly less random than picking individual stocks.
• Commodities: physical goods — gold, oil, silver, natural gas. Gold attracts traders during uncertainty. It's been called a safe haven so many times the phrase has lost all meaning, but the behaviour genuinely holds across most crisis periods.
• Cryptocurrencies: highly volatile digital assets that attract both serious traders and people who heard about it from their nephew. Both types exist in this market, which tells you something about the noise-to-signal ratio.

Most experienced traders concentrate on one or two markets. Spreading across all of them before you have a tested edge is a reliable way to be equally bad at everything. (I include myself in that critique — 2011 was a humbling year on multiple fronts.)

Trading vs. Investing: The Actual Difference

These terms get used interchangeably, which causes confusion for anyone trying to understand what they're actually doing with their money.

Investing means buying an asset and holding it for years — sometimes decades — on the expectation that its underlying value grows over time. The goal is compounding: the patient accumulation of returns. A long-term index investor isn't particularly interested in what the FTSE 100 does this Tuesday.

Trading means taking shorter-term positions — hours, days, or weeks — to profit from price fluctuations rather than long-term growth. A trader cares a great deal about what the FTSE 100 does this Tuesday, because they might be in and out by Thursday afternoon.

Neither is inherently better. They suit different goals, time horizons, and personality types. If you have a long time horizon, a low tolerance for daily volatility, and no desire to stare at charts, passive investing is almost certainly a better fit. If you have the temperament, the time to develop a genuine skill, and enough capital to absorb early losses without lasting financial damage, trading may be worth pursuing.

Who Trading Is Not For

This is the section most trading guides skip. They're trying to get you to open an account. I'm not trying to sell you anything, so here it is directly:

• If you need the money to live on, don't trade it. Risk capital is capital you can genuinely afford to lose — not rent money, not an emergency fund, not savings earmarked for something real. Trading with money you need creates a psychological pressure that reliably destroys decision-making.

• If you're drawn to it for the excitement, it won't end well. Trading looks exciting to watch. Profitable trading feels methodical. Those two things are close to opposites, and the gap between them is where most beginners lose their money.

• If you won't spend 12 months learning before trading real money, the statistics are against you. The 90-90-90 rule — 90% of new traders lose 90% of their capital in the first 90 days — is widely cited and unverified, but it circulates for a reason. Demo accounts exist precisely so you can run that process on paper first.

• If you want passive income, this isn't it. In the early years especially, trading is a second job — one that requires active attention, continuous review, and regular adaptation. It becomes more efficient as your process matures, but “passive” is the wrong word for any stage of it.

For more on who should actually pursue the independent trading route — and what the timeline realistically looks like — the honest roadmap to becoming a trader goes into the character profile that tends to survive the first two years.

What It Actually Takes

Between 70% and 80% of retail CFD traders lose money — this figure comes from ESMA-mandated disclosures by regulated brokers and has been consistent for years. The question isn't whether the odds are difficult. They are. The question is what separates the minority who build a sustainable edge from those who don't.

In my experience — and I've been trading from London since 2009, which has given me ample opportunity to observe both categories — the difference is almost never intelligence or raw market knowledge. It's process. The traders who last have a defined system, a trading journal, and the discipline to follow their rules when the market is doing everything it can to convince them otherwise.

That's it. Not a magical indicator. Not a secret strategy someone sold them on a course. A process, applied consistently, reviewed regularly, and adjusted when the evidence demands it. My apprentice still looks mildly disappointed every time I say it. He was hoping for a better answer. There isn't one.

If you want to understand what that process looks like in detail before you place a single real trade, the professional forex trading framework lays it out in full — five components, a pre-trade checklist, and the things that actually separate systematic traders from impulsive ones.
