Day trading has exploded in popularity in recent years, but what counts as a day trade, and why does it matter?
According to the Securities and Exchange Commission (SEC), day traders rapidly buy, sell, and short-sell stocks throughout the day with the hope that the stocks will continue climbing or falling in value for the seconds or minutes they hold them, allowing them to lock in quick profits.
Day trading can be a great way to make money and achieve financial independence. You can day trade almost any market, though stocks, options, index futures, cryptocurrencies, and forex are most common.
But what is day trading? What counts as a day trade? Today, we’re going to tell you some of the most important things you need to know about day trading.
And if you’ve been paying attention to the news lately, there’s something critical to add: the consequences of being classified as a pattern day trader just changed significantly. The definition of a day trade isn’t changing — but the consequences are.
What Is Day Trading?
Day trading refers to buying and selling stocks or financial instruments within a single trading day with the intention of making a profit.
When a day trader places a stock trade, they are looking to capitalize on price movements on the same day they place the trade and are not looking to hold a trade overnight.
For example, if you buy shares of GameStop ( $GME ) on Monday, you would have to sell them on the same day for it to be considered a day trade.
A Closer Look at Day Trading and the Risks
Day traders rely on sentiment and stock charts to generate trading ideas instead of using fundamental data.
These traders often deal in a small number of stocks or securities — sometimes just one — and develop detailed knowledge of how those particular securities react to events. This enables them to forecast how the price would respond and thus trade profitably.
This type of speculation is very common in stock markets and foreign exchanges. But day traders can also trade exchange-traded funds (ETFs), cryptocurrencies, bonds, or commodities like precious metals or crude. They can also trade futures or options, which are different types of derivative contracts.
Day trading is often portrayed in the media as being both a potentially highly rewarding and exciting endeavor. However, most beginner day traders lose money since this practice carries a great amount of risk and can cause one to quickly lose tens of thousands of dollars.
While most aspiring day traders are seeking financial security and freedom, one must adopt a trading strategy in order to be a successful trader.
Day traders have plenty of trading strategies at their disposal, but it’s important to point out that not every strategy works in every market cycle and may not be ideal for certain day trading styles.
If you don’t have a good trading strategy, you probably have no risk management and you are likely to join the 90% of day traders who blow up their accounts within a short time.
What Is Considered a Day Trade?
If you want to start day trading, you’ll definitely need to understand what is considered a day trade and what makes someone a pattern day trader. But before we get into the examples, it helps to understand two foundational concepts that govern how day trades are counted: FIFO accounting and partial fills.
FIFO: First In, First Out
When you have multiple open positions in the same stock and begin closing them, brokers use FIFO (First In, First Out) accounting to determine which shares are being sold. This means your earliest purchase is matched with your first sale.
Why does this matter for day trade counting? Because it determines which opening positions are considered “closed” by a given sell order, and that affects how many day trades are triggered. You’ll see this play out clearly in several of the examples below.
Partial Fills
A partial fill happens when your order is only partially executed. For example, you place a buy order for 500 shares, but only 300 are filled immediately, with the remaining 200 filled a few minutes later.
Each fill can create a separate opening position, which means a single sell order that closes both fills could count as two day trades. This catches a lot of traders off guard. Always check with your broker on how they count partial fills, as there can be slight differences in implementation.
Day Trading Examples
Example #1
On Monday morning, you buy 50 shares of stock Y. Later on that same day, you sell 50 shares of stock Y. This counts as one day trade.
Example #2
On Monday morning, you buy 100 shares of stock Y. Later on that same day, you sell 50 shares of stock Y. This counts as one day trade.
Example #3
On Monday morning, you buy 100 shares of stock Y. On Tuesday morning, you buy another 100 shares of stock Y. Later on that Tuesday, 50 shares of Y stock are sold. This counts as one day trade.
Example #4
On Tuesday morning, you buy 50 shares of stock Y. Later that same day, you sell 25 shares of stock Y, and before the closing bell, you sell another 25 shares of stock Y. This counts as one day trade. Here, although you sold your shares in two different positions, it is still considered to be one day trade since you closed out one single opening position.
Example #5
On Thursday, you buy 100 shares of stock Y. Later that day, you buy another 100 shares of stock Y. Before the closing bell that day, you sell 200 shares of stock Y. This counts as two day trades.
In this case, we have two open positions closed by a single sell order. The first batch of 100 shares was purchased and sold on the same day, and the second batch of 100 shares was also purchased and sold on the same day.
Example #6
On Wednesday, you put in 2 buy orders of 100 shares of stock Y. Later that day, you sell 101 shares of stock Y. This also counts as two day trades.
All 100 shares from the first opening position were purchased and sold on the same day. One share from the second opening transaction was purchased and sold on the same day. While you only sold a single share from Order 2, buying and selling that one share on the same trading day is considered a day trade.
Example #7
On Tuesday, you make 3 orders: Buy 2 shares of Y, Buy 5 shares of Y, and Buy 50 shares of Y. Later that same day, you sell 50 shares of stock Y. This counts as three day trades.
In this case, we match up the closing position with the opening position during that day, starting with the earliest execution time. This means you closed out all of opening order 1 and order 2, as well as part of opening order 3, thus triggering three day trades.
Example #8: Partial Fill Scenario
On Friday morning, you place a buy order for 200 shares of stock Y at market open. Due to low liquidity, 100 shares fill at 9:31 a.m. and the remaining 100 shares fill at 9:34 a.m. Later that afternoon, you sell all 200 shares in a single order. Depending on how your broker handles partial fills, this could count as two day trades rather than one.
Always verify with your broker how partial fills are tracked before assuming a single order counts as a single day trade.
Example #9: Extended Hours Trading
On Monday, during pre-market hours (8:00 a.m. ET), you buy 100 shares of stock Y. Later, during regular market hours (10:30 a.m. ET), you sell those 100 shares. Even though the buy occurred before the official market open, this counts as one day trade because both the buy and sell occurred on the same calendar day.
Pre-market and after-hours sessions are part of the same trading day for PDT counting purposes.
How Options Count as Day Trades
Options follow the same basic logic as stocks when it comes to day trading, but there are a few nuances worth understanding.
Buying a Call or Put and Selling Same Day
If you buy a call option (or put option) and sell it on the same trading day, that counts as one day trade. The underlying stock price doesn’t matter — what matters is whether you opened and closed the options position on the same day.
Spreads Opened and Closed Same Day
Options spreads (bull call spread or iron condor, for example) involve multiple legs. If you open all legs of a spread and close all legs on the same day, each leg that is opened and closed on the same day counts as a separate day trade.
So a two-legged spread opened and closed on the same day could count as two day trades. Check with your broker, as some handle multi-leg options orders differently.
Exercising an Option Same Day
If you buy an option and exercise it on the same day — meaning you convert it into shares of the underlying stock — this is generally not counted as a day trade at the options level, but the resulting stock position could trigger a day trade if you then sell those shares the same day. The specifics depend on your broker’s policies, so it’s worth confirming before you make a move like this.
Options That Expire Same Day
If you buy an option that expires worthless on the same day you purchased it, most brokers do not count this as a day trade since there was no closing sell transaction — the position simply expired. However, broker policies vary, so don’t assume. If you’re trading zero-day-to-expiration (0DTE) options frequently, confirm how your broker counts these scenarios.
Pattern Day Trader
Under the old rule, once your account was flagged as a pattern day trader, you were restricted from day trading on a margin account unless you maintained at least $25,000 in cash or qualifying securities. Your account would attract a 90-day freeze once PDT restrictions came into force.
That changed in April 2026. The SEC approved FINRA’s amendments to eliminate the PDT rule and it’s $25,000 balance requirement—one of the most significant changes to retail trading regulation in over two decades. To be clear: the definition of a day trade has not changed.
Traders only need to maintain $2,000 in their margin account. This opens the door for a much larger pool of retail traders to participate in day trading without workarounds, once their broker implements the new rules.
Many traders found this rule frustrating, and as of June 4th 2026 will no longer have it as a roadblock to trading with a smaller account.
Common Misconceptions About What Counts as a Day Trade
Even experienced traders get tripped up by some of these. Here are the most common misconceptions we see and the truth behind each one.
“I sold shares I bought yesterday — that’s a day trade, right?”
Wrong. A day trade requires both the opening and closing of a position to occur on the same trading day. If you bought shares on Monday and sold them on Tuesday, that is not a day trade. It’s a regular trade. Day trades are strictly same-day open-and-close transactions.
“I only made three trades this week, so I’m fine.”
Not necessarily. The PDT rule looks at a rolling five-business-day window, not a calendar week. If you made two day trades on Friday and two more on the following Monday, that’s four day trades within five business days, even though they occurred in two different calendar weeks.
“I bought options, and they expired worthless the same day — that’s a day trade.”
Most brokers do not count an option expiring worthless as a day trade, since there was no closing sell transaction. However, broker policies differ, particularly for zero-day-to-expiration (0DTE) options. Always verify with your specific broker rather than assuming.
“I sold short and covered the next day — does that count?”
No. Short selling and covering on different days is not a day trade. A short sale opened on Monday and covered on Tuesday is treated the same way as a regular stock position held overnight — it does not count toward your day trade tally.
“My order was filled in two parts — that’s still just one day trade.”
Not always. Partial fills can create multiple opening positions, and closing them in a single sell order may count as multiple day trades. This is one of the most common surprises traders encounter. When in doubt, check with your broker on how they handle partial fills for PDT counting purposes.
Bottom Line
If you want to become a day trader, you will need to do some planning and research. Make sure you know what you are getting yourself into before you put one dollar into day trading.
The most important thing to understand is this: the definition of a day trade has not changed. Understanding what counts as a day trade is important for understanding your metrics and tax situation, but no longer matters for the now eliminated PDT rule.
There are numerous different day trading strategies, and there are online references and courses that can help you understand the process, risk/return, and methodology. Start by studying actual strategies and trades.
Finally, and most importantly, make sure to choose a good broker who will handle your day trading account.
