How to day trade, in short: open and close every position within the same session, follow limits you wrote down before the open, and count the cost of every trade. It is written as day trading for beginners who want a routine they can actually keep, step by step and in UK time, with a one-day cost table at Ouinex rates. On Ouinex you speculate on price moves through CFDs and crypto perpetual futures, without owning the underlying asset. Whether day trading suits you is a separate question, and this guide does not try to answer it.
What is day trading, and how does it work?
Day trading means opening and closing positions within the same trading day, so nothing is held overnight. Day traders try to capture short price moves, and they pay costs on every trade, win or lose.
It is one time frame among several. The glossary entry on day trading has the full definition, and our overview of trading strategies, from scalping to position trading sets it beside the others.
How to day trade: a realistic daily routine
How to start day trading is mostly a question of habits, not indicators. For day trading for beginners, the useful test of a routine is simple: at the end of the day, can you check whether you followed it? Each of the eight steps below is written so that you can. Times are UK time.
- Before the session (30 to 45 minutes). Check the day's economic releases and their times, and what moved overnight. Mark the price levels you will act on. Then write down two numbers: the most you will lose today, and the most trades you will take.
- One or two markets, and their hours. Forex trades around the clock on weekdays, and crypto trades 24/7. The London cash session runs from 08:00 to 16:30. The US cash session runs 09:30 to 16:00 Eastern Time, which is 14:30 to 21:00 UK time for most of the year. The exception is the few weeks when the clocks change on different dates: the US moves on the second Sunday of March and the first Sunday of November, the UK on the last Sunday of March and of October. In those weeks the US session opens at 13:30 UK time, as our guide When does the US stock market open in UK time? explains.
- One written setup. State your entry conditions in one sentence you could hand to someone else, so that they would take the same trades. If you cannot write it down, it is not a setup yet. One is enough to start with.
- Size from the stop. Decide where the stop goes first, then choose the size, so that being stopped out costs a fixed share of the account. Many traders use about 1% of the account per trade: a common convention, described here, not a recommendation. Our guide How to calculate margin for a CFD or perp trade works through the numbers.
- Stop loss and take profit go in with the order. Both are set when the trade is opened, not after it. A level chosen before the trade, while you are calm, is easier to keep than one chosen while price is moving against you.
- Daily stop rules. When the day's maximum loss or maximum number of trades is reached, the session is over. The rule only works if "one more trade" is never an exception.
- Flat before the close. Close every position before the session ends and before the daily rollover on CFDs, so that no overnight financing applies. On crypto perpetuals, a position that is open at a funding time pays or receives funding.
- End-of-day log. Record every entry, exit, cost and broken rule. The log is what turns a routine into a record: after a few weeks it shows which rules you keep and which you break.
What 10 trades a day cost: one day at Ouinex rates
Every trade has a cost, and a day trader pays it many times a day. The table prices one illustrative day: 10 round trips (an open and a close each) with a position size of 1,000 (USD, or USDT on crypto) per trade. These inputs are an example only. They are not a forecast and not a recommendation.
The rates behind it: zero commission on forex, stock indices and commodities: you pay the spread and nothing else. Crypto perpetuals are 0.045%, stock derivatives 0.3%. In the examples below, both percentages are applied to the position's full value, not to the margin you put up, which is how leverage raises the cost of a trade along with its size.
Market | Commission basis | Cost of 10 round trips (1,000 each) | Holding cost if flat by the close |
|---|---|---|---|
BTC perpetual | 0.045% of notional, per side in this example | 1,000 × 0.045% × 2 × 10 = 9.00 USDT | Funding only if open at a funding time |
EUR/USD CFD | Zero commission on forex, stock indices and commodities: you pay the spread | Spread in pips × 1.00 USD (on 1,000 EUR) | None if closed before the daily rollover |
Stock index CFD | Zero commission on forex, stock indices and commodities: you pay the spread | 1,000 × (spread ÷ price) × 10, using the live spread shown on the platform | None if closed before the daily rollover |
Commodity CFD | Zero commission on forex, stock indices and commodities: you pay the spread | 1,000 × (spread ÷ price) × 10, using the live spread shown on the platform | None if closed before the daily rollover |
Stock CFD | 0.3% of notional, per side in this example | 1,000 × 0.3% × 2 × 10 = 60.00 USD | None if closed before the daily rollover |
How to read it. The table counts commission and spread only. Slippage, covered in the next section, comes on top.
The crypto perpetual, step by step. One side: 1,000 × 0.045% = 0.45 USDT. A round trip has two sides, the open and the close: 0.90 USDT. Ten round trips: 9.00 USDT. This assumes the rate is charged on each side. If it is charged once per round trip, the day's total halves to 4.50 USDT, so check the current basis on the fees page.
The stock CFD, step by step. One side: 1,000 × 0.3% = 3.00 USD. A round trip: 6.00 USD. Ten round trips: 60.00 USD, on the same per-side assumption. Charged once per round trip, the total would be 30.00 USD.
The spread markets, step by step. On forex, stock indices and commodities there is zero commission: you pay the spread, the gap between the buy and sell price, once per round trip. On a 1,000 EUR position in EUR/USD, each pip (0.0001) of spread costs 0.10 USD. Whatever the spread in pips when you trade, one round trip costs that number × 0.10 USD, and ten cost that number × 1.00 USD.
The point, in one sentence: costs are charged on every trade whatever its outcome, and they grow with the number of trades. Before you settle on a trade cap, check Ouinex rates for each market you might day trade.
Whether those costs make day trading worth it is a different question. It is worked through in our Tips guide Is day trading worth it? The cost maths, honestly, and not repeated here.
The risks, and the rules that limit them
A routine does not remove risk; it decides in advance how much you accept. These are the risks a day trader meets most often:
- Leverage amplifies both directions. A small move against a leveraged position is a large share of the margin behind it. Sizing from the stop (step 4) exists for this reason.
- Slippage around news and the open. In a fast market an order can fill at a worse price than the one you set, stop orders included. It is a real cost, and the table above does not show it.
- Spreads widen at the open, the close and around releases. The spread you pay at 08:00 or on a data release can be far wider than in a quiet hour.
- Overtrading. Every extra trade adds a cost, win or lose. The trade cap from step 1 sets a ceiling before the session starts, when you are thinking clearly.
- The pull to break the daily stop. After a loss, the urge to win it back is strongest. The daily stop only protects you if it is treated as final.
Trading CFDs and perpetual futures involves risk of loss. Leverage amplifies both gains and losses, and every trade carries costs whether it wins or loses.
Practise the routine before it costs money
How to learn day trading is less about reading and more about repeating the same routine under the same rules. Run the whole routine on a demo account for a period you set in advance, and log every trade as if it were live.
Many demo accounts leave costs out. Add the costs from the table above to your log by hand, so the record reflects what live trades would have cost.
At the end of the period, read the log for the routine, not the result. How many days did you stop at your limits? How often were you flat by the close? Which rules did you break, and when? Our guide How to learn trading: a 12-week self-study plan sets out a wider study plan. Session tactics are a separate subject, covered in our Day trading tips guide.
FAQ: how to day trade, answered
How does day trading work?
A day trader opens and closes positions within one session, so nothing is held overnight. Each trade aims to capture a short price move, follows a written setup, and has a stop loss set in advance. Every round trip pays a commission or a spread, so the number of trades drives the day's total cost.
How do you start day trading in the UK?
Pick one or two markets whose hours fit your day: the London cash session runs 08:00 to 16:30, and the US session 14:30 to 21:00 UK time for most of the year. Write down one setup, a daily loss limit and a trade cap. Then practise the full routine on a demo and keep a log.
Can you day trade crypto?
Yes. Crypto trades 24/7, so there is no closing bell: you set your own session and end it yourself. On Ouinex, crypto perpetual futures are charged 0.045%, and a position open at a funding time pays or receives funding. Being flat before each funding time avoids that cost.
What is the difference between day trading and scalping?
Scalping is a faster form of day trading. A scalper holds positions for seconds or minutes and takes many small trades; a day trader may hold for minutes or hours. Both close everything by the end of the session. Because scalpers trade more often, costs weigh more heavily on them. Our Scalping vs day trading comparison goes further.
How long does it take to learn day trading?
There is no fixed time, and no one can promise one. A better measure is your log. Once you can follow the full routine for several weeks on a demo, keeping every limit and staying flat by the close, you know the process holds. That tells you about your discipline, not about future results.
Conclusion
How to day trade comes down to a routine you can check. Write the day's limits before the open: a maximum loss and a maximum number of trades. Trade one setup, written in a sentence. Size each position from its stop, place the stop loss and take profit with the order, and be flat by the close. Log everything, costs included. Costs are the one part of day trading that is certain: every trade pays a spread or a commission, win or lose, and ten trades a day pay it ten times. Zero commission on forex, stock indices and commodities: you pay the spread and nothing else. Crypto perpetuals are 0.045%, stock derivatives 0.3%. Before you fix your own trade cap, price your own routine against current Ouinex fees.
