Module 1 · Lesson 1 of 6A financial market is simply a place, usually digital today, where people trade things of value. This lesson explains what that means, why markets exist and how a price is born.
Risk warning: CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. You should consider whether you understand how CFDs work and whether you can afford to take the high risk of losing your money. Educational content only. Nothing here is a recommendation, and no result is guaranteed.
Think of a farmers' market. Sellers set up stalls, buyers walk around, and through lots of small negotiations a price for a bag of apples emerges. Nobody in charge decides that price. It comes from the people taking part.
A financial market works the same way, except the goods are financial: shares in companies, government loans (bonds), currencies, commodities such as gold and oil, and contracts based on them. Most of the meeting now happens on computer networks rather than in a physical hall.
Markets do three useful jobs:
A market is not a single company or a machine that creates prices. It is the meeting point of everyone's orders. The price you see is the latest agreement between a buyer and a seller.
Every trade needs two sides. For each person buying, someone else is selling. If you see a price quoted on screen, there are actually two of them:
The ask is always a little higher than the bid. The gap is the spread, and it is a real cost of trading. A tight spread usually signals a busy, healthy market.
Hypothetical example. Suppose a quote shows a bid of $2,000.00 and an ask of $2,000.40 for one ounce of an asset.
If you bought and sold straight away with no price movement, you would be down $0.40 per ounce. The market has to move in your favour by at least the spread before you are even level.
The primary market is where something is sold for the first time and the money goes to the issuer. When a company sells new shares to raise cash, or a government issues a new bond, that is the primary market.
The secondary market is where those items are traded afterwards between investors. The original issuer is not paid when shares change hands here. Almost everything a retail trader does happens in the secondary market, or in markets that never involve issuing anything at all, such as currencies.
| Primary market | Secondary market | |
|---|---|---|
| What is sold | Brand new securities | Existing securities, currencies, contracts |
| Who gets the money | The issuer (company or government) | The previous owner or seller |
| Typical example | A company's first share sale | Everyday trading of shares or gold |
| Why it matters to traders | Creates the assets that exist | Provides the prices you see and trade |
The secondary market is important because it makes primary markets work. People are more willing to buy new shares if they know they can sell them later to someone else.
Liquidity describes how quickly you can buy or sell without moving the price much. Selling a house takes weeks and involves a lot of negotiation, so property is illiquid. Selling a major currency can take a fraction of a second at a tiny cost, so it is highly liquid.
A liquid market tends to show:
Illiquid markets show wide spreads and jumpy prices. A single large order can push the price noticeably, a problem called slippage when your trade fills at a worse price than you expected.
Liquidity affects your costs and your exit. A trade you cannot leave at a fair price can turn a small loss into a bigger one. Liquidity can also dry up suddenly around major news, so spreads often widen at exactly the moments when prices move fastest.
There are two broad ways a market can be organised.
An exchange is a central, regulated venue with standard rules. Orders from everyone are collected in one place, and there is one visible order book. Stock exchanges and futures exchanges work like this.
An over-the-counter (OTC) market has no single central venue. Banks, dealers and brokers trade directly with each other and with clients through networks. The global currency market is the best-known OTC market, and the gold spot market is also largely OTC.
| Exchange | Over-the-counter | |
|---|---|---|
| Venue | One central marketplace | Network of dealers and brokers |
| Contract terms | Standardised | Can be customised |
| Price visibility | One public price feed | Prices can differ slightly between providers |
| Examples | Stock and futures exchanges | Currencies, spot gold, many CFDs |
This is why two brokers can show slightly different gold prices at the same moment. There is no single official quote for OTC instruments. For more on how a retail trader connects to these markets, see Brokers and How They Make Money.
When you click buy, your order travels through several steps. The detail varies, but the shape is the same everywhere.
A market order says buy or sell now at the best available price. A limit order says buy or sell only at this price or better, and it waits until the market reaches that level. Market orders prioritise speed, limit orders prioritise price.
New to gold itself? The existing lesson Gold Trading for Beginners shows how this applies to XAUUSD.
Trading always has a counterparty, the other side of your trade. Markets do not hand out gains. One person's profit on a trade is a result of prices moving the way they bet on, and the other side of a trade may have different goals, time horizons or information.
Some still have physical trading floors, but nearly all trading is now electronic. A market is better understood as a network where orders are matched.
No single party does. The price is the latest level at which a buyer and a seller agreed, shaped by all the orders in the market.
