Being a day trader requires not only a deep understanding of market mechanics, but also a disciplined and steady mindset.

In day trading, the primary characteristic is making trades -buying and selling- within just one market day. It can be both exciting and stressful, depending on a trader's skill level and experience.

Having a concrete trading strategy trade the day is crucial in day trading. Without a clear-cut strategy, traders are prone to making rash decisions that might lead to hefty losses.

Traders have a variety of strategies to choose from- scalping, swing trading, and arbitrage are a few examples. The choice of strategies largely depends on the traders' objectives, trading style, and risk tolerance.

To excel in day trading, an investor must stay up to date with market indicators and any promising or thunderous news that may impact their trades.

Grasping the psychology of trading is equally critical as it helps in negotiating the emotional twists and turns that accompanies the uncertainties of day trading.

Summing up, day trading can yield significant financial advantages if underpinned by a robust strategy and strict discipline. However, it is not for everyone and requires a commitment to continuous learning and ability to handle financial risks.
