Day trading is an intriguing world bursting with opportunities. It involves purchasing and selling financial instruments in the span of one trading day. This means that all positions are wrapped up before the market closes for the day.

A person who participates in day trading is known as a day trader. Day traders often use high amounts of leverage and short-term trading strategies to benefit on small price movements in highly liquid stocks or currencies. However, it is not a get-rich-quick scheme; there are risks involved, and it requires a solid understanding of the financial markets.

Successful day trading requires developing a well-thought-out strategy. This involves anticipating market trends, setting realistic goals, taking calculated risks and having a strong understanding of the assets you're trading.

Strategies used in day trading vary. Some of the more common approaches include swing trading, arbitrage, and scalping. Scalping is a strategy that aims to earn from small price changes. Swing trading is more about predicting the swings in the market. And arbitrage involves buying a dual-listed stock at a lower price in one market and simultaneously selling it at a higher price in another market.

A day trader should have a comprehensive knowledge of the market. This includes knowing about market fluctuations, economic releases, and other market-related events. Keeping track of these details will help the trader make educated decisions.

Moreover, day trading requires a sizable amount of capital. Given that traders need to buy stocks, commodities, or currencies, they must have enough capital to buy these assets and possibly sell them for a trade the day profit. Depending on the market currency, the capital required for day trading can range from a few hundred to several thousand dollars.

All trading involves risks, and day trading is no different. However, with a sound strategy, these risks can be managed. It's important for traders to set a stop-loss order, which is a pre-designated point at which a trader will exit a trade if the price moves against them. This can help limit potential losses.

The world of day trading is fast-paced. There's much at stake, and the rewards can be significant. Armed with comprehensive market knowledge, a solid trading strategy, and the readiness to take calculated risks, you can navigate the turbulent seas of day trading. However, it is crucial to maintain discipline and remember the age-old adage: only invest what you are prepared to lose.

In summary, day trading is not for the risk-averse, but for those with a comprehensive understanding of the financial markets, a robust strategy and nerves of steel. It offers the chance to earn substantial profits, but it's also fraught with considerable risks. Still, with intelligent strategizing and ample trading experience, you could convert day trading into a potentially profitable venture.
