What’s the difference between day trading and swing trading?

Day trading and swing trading are two distinct styles of market speculation that aim to profit from short-term market movements.

It really boils down to two things:

A day trade can last from mere seconds to hours, while a swing trade can last from days to a few weeks.

What accounts for this difference? Most day traders prefer to avoid “overnight risk,” or the risk that the position might move against them while they’re sleeping (if it trades on a 24-hour basis) or open at an unfavorable price the next morning.

Many day traders take on large and highly leveraged positions. For example, they might trade stocks and/or options in a margin account. Some professionals day trade in the futures markets, looking for short-term price movement in stock indexes such as the S&P 500 or Nasdaq, or commodities such as gold or crude oil. In recent years, crypto markets have become a favorite of day traders.

Day traders tend to put a lot of capital at risk on any given trade, but they’re looking for a few points (or “ticks,” in futures market lingo) and they’ll get out quickly, for better or worse.

If the market makes a big move—as it can overnight—a large position can deal a whopping loss, and could result in a margin call, which is when your broker requires you to deposit more money immediately or else they’ll close out your position. In a worst-case scenario, a day trader who holds big risk overnight could “go debit,” which is trader-speak for losing more money than you have in your trading account.

In contrast, swing traders try to catch market “swings,” which are longer yet still short-term trends that often last anywhere from a day to a few weeks. The duration of the trade typically matches the duration of the swing.

If day traders are like boogie-boarders catching small waves on a dangerous and rocky shore, swing traders are further out in the ocean surfing the larger, but more slow and steady, waves.

Because swing traders must carry overnight risk, most have to adjust their position size to maximize potential profit while reducing the effect of losses.

Depending on the market, trading hours can range anywhere from 6 to 24 hours in a given day. Day traders with very short trading windows, say, seconds to minutes, may choose to maximize those hours by trading frequently throughout the day. Some day traders watch—and hold positions in—more than one stock, option, or futures product at any given time. Others look at heat maps or other indicators to see which products in their lineup might be experiencing price volatility and thus offer some opportunity to get in and out for a profit.

Swing traders, on the other hand, trade less frequently because it takes longer to complete their trades. For example, a stock might be nearing a level of long-term support or resistance, and thus poised for a possible reversal over the next few days. Sometimes, longer trade setups take longer to come to fruition.

Yes. The experience of day trading versus swing trading can be worlds apart, especially when factoring in time and market noise.

Quantity versus quality of time. It’s easy to assume that a day trade is like a swing trade sped up, or a swing trade is like a day trade in slow motion. In theory, yes; in practice, a resounding no.

Both day trading and swing trading come with their own forms of stress and anxiety.

Day trading. Fast and frequent trades can be more stressful and prone to error than slower and more calculated trades. Adding to the intensity of this pace, a day trader may be glued to a desk, staring at a screen, and constantly scanning charts in search of the next trading opportunity.

Swing trading. Enduring a slower-moving swing trade, particularly one that’s not quite working out in the way you had anticipated, brings its own unique form of stress. If you’re the impatient sort, it might be hard to sit by and wait.

That being said, swing traders have more time to plan their trades and even automate their market entries and exits. This allows swing traders to walk away from their trading screens.

In other words, there’s a “quality” to the “quantity” of time spent in the market. And it’s the qualitative experience of trading that sometimes defines each style better than the definitions themselves.

Markets are noisier when magnified in time. Market noise refers to price movements that distort an asset’s technical or fundamental trend. It’s the drunken zigzag motion that prices exhibit as they move toward a cumulative destination, higher or lower.

Here’s a general rule: The shorter the time frame in which you view the market, the greater the market noise.

Day traders looking to scalp ultra-short-term profits have to deal with much more market noise than swing traders (or long-term investors) who are trying to capture larger trends.

Both day traders and swing traders rely heavily on technical analysis to analyze and trade their markets. That’s because the effects of market fundamentals (or the underlying “economics” of a given market) can be slow to appear.

Yet, micro levels of supply and demand do cause markets to move on a smaller time scale. Day traders and swing traders aim to exploit these smaller movements for profit, from the most miniscule of micro-trends to price swings that appear over weeks.

Where fundamentals are generally ineffective in helping a trader navigate a short-term market landscape, technical data may provide just the right toolset.

Neither day trading nor swing trading are necessary for every investor. To be successful with either style, you’ll need to have a strong grasp of technical analysis or transactional (i.e., volume and order flow) analysis to make your way through the magnified crevices where the light of economic fundamentals often doesn’t shine.

If you’re interested in trying your hand at either of these short-term trading styles, start small and move cautiously. The experience of day trading or swing trading versus investing can be like night and day. But for those who do get the hang of one (or both), short-term trading can be a useful skill that complements a much longer-term investment approach.

In its own way, placing a portion of your investment portfolio into short-term trading strategies adds an additional layer of diversification—something that might be working when other portions of the portfolio aren’t.
