Understanding CFDs, forex & financial markets β a beginner's guide
Never traded before? No problem. This guide explains everything from scratch β what CFDs are, how forex works, what it costs, and how to manage risk. We use plain language and real-world examples throughout. By the end, you will have a solid foundation to start exploring the markets β and we will also explain how our free demo account can help you practise before risking any real money.
What are CFDs?
What is a Contract for Difference?
A Contract for Difference (CFD) is an agreement between you and your broker to exchange the difference in the price of a financial instrument β such as a currency pair, commodity, or index β between the time you open your position and the time you close it.
Crucially, you never buy or own the underlying asset. If you open a CFD on Apple shares, you do not receive Apple shares. Instead, you receive a contract that tracks the price movement. If the price moves in your favour, your broker pays you the difference. If it moves against you, you pay your broker.
How CFDs differ from traditional investing
When you buy a share traditionally, you pay the full price and become a shareholder. With a CFD, you pay only a fraction β a deposit called margin β and enter into a contract to exchange price differences.
| Feature | Buying shares (traditional) | Share CFD |
|---|---|---|
| Do you own the shares? | β Yes β you're a shareholder | β No β you hold a contract |
| Capital required | Full share price (e.g. $5,000) | A deposit only (e.g. $500 with 10:1 leverage) |
| Profit from falling prices? | β Not without complex strategies | β Yes β by going short |
| Receive actual dividends? | β Yes | Dividend adjustments applied |
| Overnight costs? | β None | Financing charge each night |
| Best suited for | Long-term investing | Short-to-medium-term speculation |
Going long and going short β two ways to trade
One of the things that makes CFDs so different from traditional investing is the ability to profit in both rising and falling markets. However, both directions carry the risk of loss.
π Going long β market rises
You believe the price will rise. You open a buy position.
Example: You buy the US 500 at 5,200. It rises to 5,400. You close.
π Going long β market falls
You believe the price will rise, but it moves against you.
Example: You buy the US 500 at 5,200. It falls to 5,000. You close.
π Going short β market falls
You believe the price will fall. You open a sell position.
Example: You sell the US 500 at 5,200. It falls to 5,000. You close.
π Going short β market rises
You believe the price will fall, but it moves against you.
Example: You sell the US 500 at 5,200. It rises to 5,400. You close.
Think of it like this: imagine you borrow a friend's rare book, sell it today for $100 because you think the price will drop, then buy an identical copy next week for $80 and return it to your friend. You have made $20 profit β without ever owning the book permanently.
In CFD trading, the broker facilitates this process electronically. You simply open a "sell" position and the broker calculates your profit or loss based on how the price moves.
How CFDs work in practice
Leverage and margin β trading more than you deposit
Leverage is one of the most important β and most misunderstood β concepts in CFD trading. It allows you to control a position much larger than the money you deposit. But it is also why CFDs carry such significant risk.
When you buy a house worth $200,000 with a $20,000 deposit and a $180,000 mortgage, you are using 10:1 leverage. You control a $200,000 asset with only $20,000 of your own money. If the house rises 10%, you make $20,000 on your $20,000 deposit β a 100% return. If it falls 10%, you have lost your entire deposit.
CFD leverage works exactly the same way β but markets can move far faster than property prices.
Leverage is expressed as a ratio. Cynvest offers leverage up to 1:1000 on major forex pairs. The amount available depends on the asset class:
| Asset class | Max leverage (Cynvest) | Margin on $10,000 position |
|---|---|---|
| Major forex pairs | 1:1000 | $10 |
| Gold & major indices | 1:500 | $20 |
| Commodities | 1:100 | $100 |
| Share CFDs | 1:20 | $500 |
| Cryptocurrency | 1:10 | $1,000 |
What is margin?
Margin is the deposit required to open and maintain a leveraged position:
- Initial margin: The deposit required to open a position β calculated as a percentage of the full position value.
- Maintenance margin: The minimum you must keep in your account to hold a position open. If you fall below this, you will receive a margin call.
Spreads β the cost of every trade
When you look at any CFD price, you will see two prices: the bid (the price you can sell at) and the ask (the price you can buy at). The difference between these two prices is the spread.
You look at EUR/USD and see: Bid: 1.08501 Β |Β Ask: 1.08521
The spread is 0.00020, or 2 pips. If you click Buy, you enter at 1.08521. The market must rise above this before you break even.
On a trade of 10,000 units, a 2-pip spread costs approximately $2. On larger trades this adds up.
A full trade walkthrough β step by step
Let's follow a trader through a complete CFD trade to see how everything works together.
The US 500 is at 5,200. Alex believes it will rise to 5,350. He decides to buy 2 contracts at $1 per point per contract.
Full position value: 5,200 Γ 2 Γ $1 = $10,400. With 200:1 leverage, margin required = $10,400 Γ· 200 = $52. Alex has plenty of buffer in his $2,000 account.
Stop-loss at 5,100 (100 points below entry = max $200 loss). Take-profit at 5,350 (150 points = potential $300 gain). Risk/reward: 1:1.5.
Over four days the US 500 rises to 5,350. His take-profit triggers. He held for 4 nights, incurring overnight financing of approximately $8.
Gross profit: (5,350 β 5,200) Γ 2 Γ $1 = $300. Less financing: β$8. Less spread: ~β$2. Net profit: ~$290, credited to his account.
β Market rose β Alex's outcome
Entry: 5,200 | Exit: 5,350 | Move: +150 points
Gross P&L: +$300 | Costs: β$10
β If market had fallen
Entry: 5,200 | Stop-loss: 5,100 | Move: β100 points
Gross P&L: β$200 | Costs: β$6

Forex explained
What is the forex market?
The foreign exchange market is where the world's currencies are bought and sold. It is the largest financial market on the planet, with over $7.5 trillion traded every single day. Unlike stock markets which have central exchanges, forex has no single location. It is a global, decentralised network operating 24 hours a day, five days a week across four main sessions: Sydney, Tokyo, London, and New York.
If you have ever exchanged currency at an airport or bureau de change, you have participated in the forex market. You bought one currency by selling another. The key difference when trading forex CFDs is that you are speculating on whether one currency will strengthen or weaken against another β with leverage amplifying both gains and losses.
Reading currency pairs
In forex, currencies are always traded in pairs β you are always buying one currency and selling another simultaneously. The pair is written as two three-letter codes separated by a slash.
GBP = British pound sterling (the base currency β the one you are buying or selling)
USD = US dollar (the quote currency β measuring the base against this)
If GBP/USD = 1.2700, it means 1 British pound buys 1.27 US dollars. If you think the pound will strengthen, you buy. If you think it will weaken, you sell.
| Pair type | Examples | Characteristics |
|---|---|---|
| Major pairs | EUR/USD, GBP/USD, USD/JPY, AUD/USD | Always include USD. Most traded, tightest spreads, highest liquidity. Best for beginners. |
| Minor pairs (crosses) | EUR/GBP, GBP/JPY, EUR/AUD | No USD. Moderate liquidity, slightly wider spreads. |
| Exotic pairs | USD/TRY, GBP/ZAR | One major + one emerging market currency. Wide spreads, high volatility. Not recommended for beginners. |
What is a pip?
In forex, the smallest standard unit of price change is called a pip (percentage in point). For most major currency pairs, a pip is the fourth decimal place β 0.0001.
You are trading EUR/USD. The price moves from 1.0850 to 1.0870 β a move of 20 pips.
Trading 1 mini lot (10,000 units): 1 pip β $1. Profit: 20 Γ $1 = $20.
On a standard lot (100,000 units): 1 pip β $10. Same 20-pip move = $200 profit.
A complete forex trade walkthrough
GBP/USD: Bid 1.27010 / Ask 1.27030. James buys at 1.27030. He trades 1 mini lot (10,000 units). Each pip β $1.
Stop-loss 50 pips below at 1.26530 (max loss ~$50). Take-profit 100 pips above at 1.28030.
GBP/USD jumps. James's take-profit at 1.28030 triggers β the pair moved 100 pips in his favour.
Gross profit: 100 pips Γ $1 = $100. Less 2-pip spread ($2) and overnight financing (~$0.50). Net profit: ~$97.50, credited immediately.
β Trade goes in James's favour
Entry 1.27030 | Exit 1.28030 | +100 pips
β If trade goes against him
Entry 1.27030 | Stop 1.26530 | β50 pips
Other markets you can trade
Forex is just one of many markets available through Cynvest. Here is an overview of the others and what makes each distinctive.
Indices β trading the whole market at once
A stock market index measures the performance of a group of companies. Trading an index CFD gives you exposure to an entire market in a single position.
Think of the US 500 (S&P 500) like a scoreboard of the 500 biggest US companies. If most companies are rising, the index goes up. If most are falling, it goes down. Trading an index CFD is like betting on whether that scoreboard will be higher or lower by the time you close your trade.
UK 100 (FTSE 100)
The 100 largest companies on the London Stock Exchange. Includes Shell, HSBC, Unilever, and AstraZeneca.
US 500 (S&P 500)
The 500 largest US-listed companies. The benchmark for the US economy. Includes Apple, Microsoft, Amazon, and Tesla.
US Tech 100 (Nasdaq)
100 of the largest Nasdaq companies. Heavily weighted toward technology β Apple, Nvidia, Alphabet, and Meta.
Germany 40 (DAX)
The 40 largest German companies. Europe's most traded index. Includes Volkswagen, Siemens, and BMW.
Commodities β trading physical goods
Commodities are raw materials β gold, silver, oil, and agricultural products. Their prices are driven by supply and demand, geopolitical events, weather, and global economic conditions.
When conflict breaks out in a major oil-producing region, the supply of oil is threatened and prices rise. When a major new oil field is discovered, supply increases and prices can fall. Commodity CFD traders try to anticipate these supply and demand changes β without ever physically buying a barrel of oil or an ounce of gold.
Gold (XAU/USD)
The most popular commodity CFD. A "safe haven" β tends to rise in times of uncertainty or inflation. Often moves inversely to the US dollar.
Oil (WTI & Brent)
The world's most traded commodity. Prices react sharply to OPEC decisions, geopolitics, and inventory data.
Silver (XAG/USD)
Follows gold trends but with higher volatility. Has both investment demand and industrial demand from solar panels and electronics.
Agricultural commodities
Wheat, corn, and coffee CFDs allow traders to speculate on food prices. Highly sensitive to weather events and harvest reports.
Risks & costs β what every beginner must know
Key risks explained plainly
1. Leverage risk β the double-edged sword
Leverage is the single biggest risk for new traders. A 5% adverse price move on a 20:1 leveraged position wipes out your entire margin deposit. Forex markets can move 5% in a matter of minutes.
With leverage: the upside
You deposit $500 to control a $10,000 position (20:1). The market rises 3%.
With leverage: the downside
You deposit $500 to control a $10,000 position (20:1). The market falls 3%.
2. Market risk β prices don't always do what you expect
Economic data releases, central bank decisions, political events, and even social media can cause sudden sharp price movements. Stop-loss orders are one of the tools available to help limit exposure to unexpected moves.
3. Gap risk β when markets jump overnight
Markets sometimes "gap" β jumping from one price to another without trading through the levels in between. This typically happens over weekends or after major overnight news. A stop-loss cannot guarantee execution at your stated price in these conditions.
You hold a long position on company shares over the weekend. Your stop-loss is set at $4.80 (you entered at $5.00). On Saturday, news breaks that the CEO has resigned. When markets open Monday, the share gaps down to $4.30 β skipping past your stop-loss. Your position closes at $4.30, not $4.80, resulting in a larger loss than expected.
This is why holding positions over weekends or major news events carries additional risk.
4. Overnight financing β the hidden cost of holding
Every night you hold a CFD open, you pay a small financing charge. For short-term trades this is usually small. For positions held over weeks or months, daily charges can add up and significantly eat into profits β or compound a loss.
Example: If you hold a $10,000 position with a daily financing charge of 0.02%, you pay $2 per night. Over 30 days, that is $60 in charges alone β regardless of whether your trade is profitable.
CFDs are generally considered short-term trading instruments, not long-term investments.
5. Emotional risk β the risk of your own behaviour
Fear and greed lead to common mistakes: closing winning trades too early, holding losing trades too long, and doubling down on losing positions ("revenge trading"). Having a trading plan and sticking to it is as important as any technical tool.
All costs, clearly listed
| Cost type | What it is | When it applies |
|---|---|---|
| Spread | Gap between buy and sell price | Every trade, on entry |
| Overnight financing | Daily charge for holding leveraged positions | Each night a position is held open |
| Commission (ECN) | $4 per round turn on ECN accounts | On open and close of each ECN trade |
| Currency conversion | Fee when account currency differs from instrument | On close, where applicable |
Risk management tools available to you
Automatically closes your position if the market reaches a specified adverse price. Note: in gapping markets, actual execution may differ slightly from the stated price.
Closes your position automatically when it reaches your target price, locking in your gain without requiring you to monitor the screen.
Follows the market as it moves in your favour. If the price then reverses by the trail amount, the position closes β locking in profit while allowing further upside.
Knowledge check β test yourself
Work through these questions to check your understanding. Don't worry if you get some wrong β just go back and re-read the relevant section.
Demo trading β practise before you go live
Cynvest offers all clients a free demo trading account. You can explore the platform, place trades, and test your strategy using virtual money with no risk to your real funds. We strongly encourage all new traders to spend time on demo before opening a live account.
What is a demo account?
A demo account is a simulated trading environment that mirrors real markets. You are given a balance of virtual funds β typically $10,000 β and you can open and close positions on real market prices, just as you would on a live account. No real money is deposited and no real money can be lost.
Benefits of demo trading
- Learn the platform: Get comfortable navigating MT5, placing orders, setting stop-losses and take-profits, and reading charts β before any real money is involved.
- Test your strategy: Try out trading ideas and see how they play out in real market conditions without financial consequence.
- Build confidence: Familiarity with the platform reduces the chance of making costly errors β such as accidentally opening a larger position than intended β when trading with real money.
- No pressure: Because there is no real money at stake, you can make mistakes and learn from them freely.
Important limitations of demo trading β please read carefully
1. Virtual funds vs real money β the psychology gap
On a demo account, you might have $100,000 of virtual funds. On a live account, you may deposit $500 of your own money. This changes everything about how you trade.
Imagine playing poker with chips that have no cash value. You might bet boldly and not feel stressed when you lose β because nothing real is at stake. Now imagine playing with your own money. Every decision feels different. Demo trading is the chip version. Live trading is the real money version.
2. Position sizing is fundamentally different
With $100,000 of virtual funds, a $5,000 position feels small. With $1,000 of real funds, the same position would be your entire account balance. This can give a misleading picture of both profitability and risk.
3. Execution and slippage
On demo, orders typically fill at the quoted price. In live markets, during fast-moving conditions, your order may fill at a slightly different price β this is called slippage. Demo does not always replicate this.
4. Margin requirements feel very different on a live account
With a large virtual balance, margin is rarely something you need to think about on demo. On a live account with a small deposit, a relatively small adverse move can rapidly eat through your available margin and trigger a margin call.
5. Emotional discipline is not tested on demo
Fear, greed, and the temptation to make impulsive decisions are simply not present when trading virtual money. Demo trading cannot teach you emotional discipline β one of the most critical skills in live trading.
Moving from demo to live β things to consider
Your first live deposit should be an amount that, if lost completely, would not affect your financial wellbeing. CFD trading involves significant risk and is not a reliable way to generate income.
Even if you were trading large positions comfortably on demo, start much smaller on live. Give yourself time to adjust to the emotional reality of real money before scaling up.
Record every trade β your reasoning for entering, the outcome, and how you felt. This helps you identify patterns in your decision-making and improve over time.
Determine your maximum acceptable loss before you enter a trade β not during or after. Stop-loss orders can help limit losses by automatically closing a position at a specified adverse price.
Even experienced traders have losing trades. The goal is not to avoid all losses β it is to manage them so your winning trades outweigh your losing ones over time.
CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. A significant proportion of retail investor accounts lose money when trading CFDs. You should consider whether you understand how CFDs work and whether you can afford to take the high risk of losing your money.
