To trade forex online, you practise on a free MetaTrader 5 (MT5) demo account, then open a live account and place each trade with a stop loss and a size worked out from your risk. Everything happens in an app on your phone or computer, five days a week.

Forex (foreign exchange) is the buying of one currency with another. It is the largest market in the world: the Bank for International Settlements found that forex trading reached $9.6 trillion a day in April 2025. Online, you do not exchange cash. You take a position on a pair such as EURUSD or USDZAR rising or falling, through a trading account with a broker.

This guide walks through the nine steps from zero to a first live trade, with one trade worked out in dollars, the costs, how much money you need and the mistakes to avoid. Each step links to the lesson in this course that covers it in full.

What do you need to trade forex online?

To trade forex online you need a phone or computer, the free MetaTrader 5 app, a trading account with a broker, a deposit, and a written trading plan. The platform and a demo account cost nothing, so you can learn everything before you deposit.

How do you trade forex online, step by step?

The nine steps are: learn the basics, install MT5, practise on demo, choose a pair and a time, decide the direction, size the trade, place it with a stop, then review and go live. Steps 1 to 3 cost nothing and take a few weeks; steps 4 to 9 repeat on every trade.

Nine steps in two rows. Once and free: 1 learn the basics, 2 install MetaTrader 5, 3 practise on demo for 30 or more trades. Then on every trade: steps 4 to 6 plan the pair, time and reason, 7 size from the stop, 8 place the trade with a stop, 9 review it in a journal, with an arrow from review back to plan
Steps 1 to 3 happen once and cost nothing; steps 4 to 9 repeat on every trade, and each review feeds the next plan.

1. Learn how forex works

A forex price is quoted as a currency pair: EURUSD at 1.1193 means one euro costs 1.1193 US dollars. You buy if you expect the first currency to rise against the second and sell if you expect it to fall. Price moves are counted in pips, and what a pip is worth depends on your lot size, as lots, pips and pip value explains. The Market Basics module covers this from the start.

2. Install MetaTrader 5

Download MT5 from Google Play, the App Store or the MetaQuotes site, or use the web terminal in a browser. It is free on every device. The installation lesson shows each version and how to log in with your login, password and server.

3. Practise on a demo account

Open a demo account with the balance you plan to deposit and trade it as if it were real: stop loss on every trade, a fixed risk per trade and a journal. Move on after 30 or more trades that followed your plan. The demo account lesson has a four-week practice plan.

4. Choose a currency pair

Start with one or two liquid pairs, such as EURUSD, GBPUSD or USDJPY, so spreads stay low and price behaviour becomes familiar. Liquidity is what keeps spreads tight. The best forex pairs to trade guide compares the majors by spread, movement and session.

5. Choose your trading time

The forex market runs 24 hours a day on weekdays, but each pair is busiest when its home markets are open. For EURUSD and GBPUSD that is the London session and the London–New York overlap, about 13:00 to 17:00 UTC in winter: 14:00 to 18:00 at UTC+1 (West and Central Africa), 15:00 to 19:00 at UTC+2 (Southern Africa), 20:00 to 00:00 at UTC+7 (mainland Southeast Asia) and 21:00 to 01:00 at UTC+8 (maritime Southeast Asia and East Asia). See forex trading sessions and the forex market hours tool.

6. Decide the direction, and the reason

Write down why you are buying or selling before you trade: for example, price is in an uptrend and has pulled back to a support level. The setup also tells you where the idea is wrong, which is where your stop loss goes. Trends and ranges covers how to read the direction.

7. Size the trade from your stop

Decide how much of the account you will risk (many traders use 1% or less), measure the stop distance in pips, and work out the lot size: lots = money at risk ÷ (stop in pips × pip value per lot). The position size calculator does it for any pair, and position sizing explains the method.

8. Place the trade with a stop loss and take profit

In MT5, press F9 or tap the trade button, choose the pair, enter the volume, the stop loss and take profit, and tap Buy or Sell. The first trade lesson walks through it on phone and computer.

9. Review the trade, then go live

Log every trade in a trading journal: the setup, the entry, the exit and whether you followed the plan. Once your demo trades show you follow the plan every time, open a live account, deposit, and trade the same plan at the same size.

What does one forex trade look like, from plan to close?

One EURUSD trade on a $1,000 account risks 1%, or $10, with a 25-pip stop and a 50-pip target, so the size is 0.04 lot and the target is worth $20. It follows steps 4 to 8 above, with the results in US dollars.

Step Decision Numbers
Pair and time EURUSD in the London–New York overlap
Direction Buy at a support level in an uptrend Entry 1.1193
Stop loss Below the support level 1.1168, 25 pips below entry
Take profit At the last swing high 1.1243, 50 pips above entry
Risk 1% of $1,000 $10
Size $10 ÷ (25 pips × $10 per pip per lot) 0.04 lot, worth $0.40 per pip
Margin at 1:100 0.04 lot = 4,000 euros × 1.1193 = $4,477.20; ÷ 100 $44.77

How it can end, after a 1-pip spread that costs 1 × $0.40 = $0.40:

Outcome Before costs After the spread
Take profit hit (+50 pips) +$20.00 +$19.60
Stop loss hit (−25 pips) −$10.00 −$10.40

The plan risks $10 to make $20, a 1 : 2 risk-reward ratio. Even with fewer than half the trades winning, a plan like this can stay ahead, which is why the size and stop matter more than any single result.

How much money do you need to start trading forex online?

You can start trading forex online with a small deposit, such as $100, because MT5 trades from 0.01 lot, where a pip on EURUSD is worth about $0.10. What matters is that your stop loss times that size stays within the amount you plan to risk, and the demo account costs nothing.

Deposit 1% risk per trade Size for a 20-pip stop on EURUSD Loss if the stop is hit
$100 $1 $1 ÷ (20 × $10) = 0.005, so the minimum 0.01 lot 20 × $0.10 = $2, which is 2%
$500 $5 $5 ÷ (20 × $10) = 0.025, rounded down to 0.02 lot 20 × $0.20 = $4, which is 0.8%
$1,000 $10 $10 ÷ (20 × $10) = 0.05 lot 20 × $0.50 = $10, which is 1%

On a very small account, the minimum lot can push the risk above 1%, so either use a shorter stop with a setup that suits it or start with a deposit that lets the minimum lot fit your rule. Trading capital management covers how to plan a deposit.

Can you trade forex online on your phone?

Yes, you can trade forex online on your phone: the free MetaTrader 5 app for Android and iPhone lets you read charts, place and close trades, and set stops and alerts. You log in with the same account as on a computer, and your positions show on every device you log in from.

Phone trading works best with a few habits: place every order with its stop loss attached, so a dropped connection does not leave a trade unprotected; set price alerts instead of watching charts all day; and check whether you are on the demo or live account before each trade. The country guides cover phone-first set-ups, funding and local hours.

What does it cost to trade forex online?

Trading forex online costs the spread on every trade, commission on some account types, and a swap for each night a position stays open. The MT5 platform and a demo account are free, and the spread and any commission are paid whether a trade wins or loses.

Cost When you pay it Example on 0.04 lot of EURUSD
Spread When you open a trade 1 pip × $0.40 = $0.40
Commission Per trade, on some accounts Shown in your account terms
Swap Each night a position stays open Set per lot, can be a charge or a credit

How each is calculated is in spread, commission and swap, and the trading cost calculator adds them up for a planned trade.

How do you avoid the common beginner mistakes?

You avoid the common beginner mistakes by fixing a handful of habits: trading without a stop loss, risking too much per trade, trading too many pairs, and changing the plan after a loss. Each one has a simple fix you can build into your routine on a demo account before you trade a live one.

The full list, with numbers, is in why beginners lose.

Try it on demo

Open an MT5 demo account with the balance you plan to deposit. Pick EURUSD or USDZAR, mark one support or resistance level on H1, and plan one trade on paper: entry, stop loss, take profit and the size for 1% risk. Place it with the stop and target attached, log it in a journal, and repeat for ten trades before reviewing the results.

Frequently asked questions

Can I trade forex online with no experience?

Yes, but start on a demo account. It uses live prices and virtual money, so you can learn the platform, the order window, stop losses and position sizing without risking a deposit. Move to a live account once you follow your plan on every demo trade.

Is online forex trading open 24 hours?

The forex market trades 24 hours a day from Monday to Friday, passing from Sydney and Tokyo to London and New York. It closes at the weekend. Each pair is most active, with the tightest spreads, when its home markets are open.

What app do I use to trade forex online?

MetaTrader 5 is the most widely used trading app for forex. It is free on Android, iPhone, Windows and Mac, and runs in a browser. You log in with the account details your broker gives you, or open a demo account inside the app.

Can I learn forex trading online for free?

Yes. This academy’s course is free, from Market Basics to advanced strategy, and an MT5 demo account is free too. Together they let you learn and practise every step before you deposit any money.

What time of day should I trade forex online?

Trade when your pair's home markets are open. For EURUSD and GBPUSD the busiest window is the London–New York overlap, about 13:00 to 17:00 UTC in winter and an hour earlier in the northern summer. That is 14:00 to 18:00 at UTC+1 and 21:00 to 01:00 at UTC+8 in winter.
