Intraday trading means buying and selling a security within the same trading day and closing every position before the session ends. “Intraday” means “within the day”: anything between the open and the close, including the prices an asset trades at, the high and low it touches, and the trades placed to profit from those moves. An intraday trader is not betting on where an asset will be next month. They trade the swings that unfold over minutes or hours, then go flat so nothing is carried overnight.

What Intraday Means in Trading

The term shows up in three related ways.

Intraday price movement. This is the path a price takes during the session. A stock might open at one level, fall, recover and close near where it started. Someone looking only at daily closing prices would see almost no change. An intraday trader would see several tradable swings.

Intraday high and low. The intraday high is the highest price reached during the session; the intraday low is the lowest. Together they make up the “day’s range.” A “new intraday high” means the price has just exceeded every other price traded so far that day.

Intraday vs. interday. Intraday compares points within one session. Interday compares one day with another, for example today’s close against yesterday’s close. A daily chart is an interday view; a five-minute chart is an intraday view.

In stock markets, the session has a defined open and close, so “intraday” is easy to pin down. Forex is different. The currency market runs 24 hours a day, five days a week, passing from the Asian session to London and then New York, so there is no single exchange close. In practice, forex traders treat the daily rollover (5 p.m. New York time at most brokers) as the end of the trading day. A position still open at rollover is charged or credited swap, which is the cost of holding it overnight.

How Intraday Trading Works

An intraday trader works from real-time charts and order flow rather than quarterly earnings or long-term fundamentals. The core cycle is simple: identify a setup, enter, manage the position with a stop-loss and target, and exit before the session ends, whether the trade worked or not.

Chart timeframes. Intraday charts use short intervals such as one, five, 15, 30 and 60 minutes. Scalpers lean on one- and five-minute charts; traders holding for several hours tend to use 30- and 60-minute charts. The holding period, not the chart interval, defines the style: a trade held four hours on a five-minute chart is still intraday if it closes the same day.

Margin and leverage. Intraday traders often use margin, which lets them control a position larger than their account cash. Leverage magnifies gains and losses equally. A 2% adverse move on a position leveraged 10 to 1 is a 20% loss of the margin committed.

VWAP. The volume weighted average price is the sum of (price × volume) for every trade divided by the total volume traded so far in the session. Traders use it as a benchmark for whether they bought or sold well relative to the day’s activity, and VWAP orders spread a large order across the session rather than filling it all at once.

Closing out. The intraday trader exits all positions before the close. Some brokers automatically close certain intraday positions near the end of the session; the rules vary by broker and product.

Intraday Trading Strategies

• Scalping: taking many small profits from small price changes throughout the day. Each trade aims for a few cents or a few pips, so costs and execution speed matter more than in any other style.
• Range trading: buying near support and selling near resistance while price stays inside a defined band, which depends on identifying support and resistance correctly.
• News-based trading: trading the volatility around scheduled releases such as central bank decisions, inflation data or employment reports, or unscheduled headlines. Spreads can widen and fills can slip during these moments.
• Breakout and momentum trading: entering when price pushes through the morning range or a key level, on the expectation that the move continues.
• High-frequency trading: algorithmic strategies that exploit very small, short-lived inefficiencies, run by firms with specialized technology rather than by manual retail traders.

Examples of Intraday Trading

Example 1: A stock range

Suppose a stock opens at $50.00, drops to $49.20 by mid-morning, rallies to $51.10 in the afternoon and closes at $50.80. The intraday low is $49.20, the intraday high is $51.10, and the day’s range is $1.90. An interday view shows only a $0.80 gain from open to close. A trader who bought 200 shares at $49.40 and sold at $50.90 would capture $1.50 per share, or $300 before commissions, without holding anything overnight.

Example 2: A forex trade with costs

Assume a trader buys one standard lot (100,000 units) of EUR/USD. With USD as the quote currency, one pip is worth $10 per standard lot. The trader sets a stop 15 pips below entry and a target 25 pips above.

• If the target hits, the gross profit is 25 × $10 = $250.
• If the stop hits, the gross loss is 15 × $10 = $150.
• Assume a spread of 1 pip and a commission of $3.50 per side. The spread costs $10 once per round trip (paid on entry because you buy at the ask). Commission is $7 for the round trip. Total cost: $17 per trade, whether it wins or loses.

The net result is $233 on a win and a $167 loss on a stop-out. In practice, traders size positions from the stop distance and the share of the account they are willing to risk, which a position size calculator works out.

Example 3: How costs scale

Using the same $17 assumption, a trader who places 10 round trips a day pays $170 a day in costs. Over 20 trading days that is $3,400 before a single pip of profit. For a scalper targeting 5 pips per trade, a $17 cost consumes about a third of a $50 winner.

Pros and Cons of Intraday Trading

Advantages

• No overnight exposure: earnings reports and economic releases that land before the open or after the close cannot gap an open position.
• Tight stop-losses can cap the loss on each trade.
• Access to margin allows larger positions than account cash alone.
• Frequent trades create many feedback points for learning what works.

Disadvantages

• Commissions and spreads add up with every trade.
• A position may not have enough time to reach its profit target before it must be closed.
• Losses can build quickly, especially on margin.

Risks and Rules to Know

The largest risk is losing a large amount of money in a short time. Earning a consistent long-term profit is difficult, particularly for new traders still learning execution and risk control.

Tight stops reduce but do not eliminate risk. A stop-loss order is a trigger, not a guaranteed price: once it triggers it becomes a market order, and in fast markets the fill can be worse than the stop level. That gap between trigger and fill is slippage.

In the United States, FINRA’s pattern day trader rule applies to margin accounts with broker-dealers. A customer who makes four or more day trades within five business days (where those trades exceed 6% of total trades in that period) is classified as a pattern day trader and must keep at least $25,000 in equity in the account to continue day trading. The rule applies to securities such as stocks and options, not to spot forex. Other countries set their own leverage limits and account rules.

Why Mutual Funds Can’t Be Traded Intraday

A mutual fund’s price is its net asset value (NAV): the value of its holdings minus liabilities, divided by shares outstanding. The NAV is calculated once per day after the market closes. Buy and sell orders placed during the day all execute at that next calculated NAV, so there are no intraday price changes to trade.

Exchange-traded funds solve this. An ETF trades on an exchange like a stock, so its market price moves throughout the session and it can be bought and sold intraday.

Intraday Trading vs. Day Trading

The two terms describe the same practice: opening and closing positions within one session. “Intraday” is the broader word, also used for data and prices (intraday chart, intraday high), while “day trading” names the activity and the trader. Swing trading is the contrast, holding positions for several days to capture interday moves and accepting overnight risk in exchange.

How to Learn Intraday Trading

1. Learn to read intraday charts: candlesticks, the day’s range and how volume behaves around the open and close.
2. Pick one market and session. A forex trader chooses the session where their pair is most active.
3. Choose one strategy and write precise entry, stop and exit rules.
4. Calculate costs before trading: spread, commission per round trip and margin requirements.
5. Practice without real money in a paper trading simulator.
6. Set a daily loss limit and stop trading when it is reached.
7. Keep a trade journal recording the setup, result and costs of every trade.

FAQs

The Bottom Line

Intraday trading suits traders who want to avoid overnight gaps and can manage fast decisions, tight stops and frequent costs. Spreads, commissions and slippage can consume a large share of small winners, and leverage magnifies losses as much as gains. Calculating costs in advance, practicing on a simulator, setting a daily loss limit and keeping a journal give a new trader a measured way to start.
