Day trading is a strategy that involves buying and selling financial assets within a single trading day. A day trader closes out all their positions before the market closes. The goal isn't to hold onto an asset for long-term growth. Instead, the aim is to profit from small price fluctuations throughout the day.

This high-frequency approach means traders might make dozens or even hundreds of trades daily. Success relies on capitalizing on small, predictable market movements. It's an active, hands-on style of trading that demands focus and discipline.

Trading and investing strategies exist on a spectrum, primarily defined by the time an asset is held. Day trading sits at the shortest end of this spectrum.

Swing traders hold positions for more than a day but usually less than a few weeks. They aim to capture a larger price move, or "swing," than a day trader would.

Long-term investors, on the other hand, hold assets for months, years, or even decades. They're typically focused on the fundamental value of a company or asset, believing it will grow significantly over time. They are less concerned with daily price noise.

Day traders need markets with two key ingredients: volatility and liquidity. Volatility ensures that prices move enough during the day to create profit opportunities. Liquidity means there are enough buyers and sellers to enter and exit trades quickly without affecting the price too much.

Some of the most common markets for day trading include:

• Stocks: Trading shares of publicly traded companies.
• Forex (Foreign Exchange): Trading currency pairs, like the Euro versus the U.S. Dollar (EUR/USD).
• Commodities: Trading raw materials like oil, gold, or corn, often through futures contracts.

Getting started in day trading involves more than just opening a brokerage account. It requires a certain level of preparation and resources.

First, you need sufficient trading capital. This is money you can afford to lose. In the U.S., regulations require traders who execute four or more day trades in a five-day period to maintain a minimum account balance of $25,000. This is known as the pattern day trader (PDT) rule.

Second, you need the right equipment. A reliable, fast computer and a stable, high-speed internet connection are non-negotiable. A missed trade due to a technical glitch can be costly. Many serious traders use multiple monitors to track charts, news, and their trading platform simultaneously.

Now that you understand the basics, let's check your knowledge.

Understanding these core concepts is the first step. Day trading is a distinct discipline that differs significantly from longer-term approaches to the market.
