What is a stop loss in trading and why is it important for risk management?

A stop loss in trading is a predefined price level that automatically closes your position when the market moves against you. It is one of the most important tools used in risk management for stock trading and crypto trading, especially for beginners and active traders who cannot monitor markets continuously.

When you enter a trade, you decide in advance how much loss you are willing to accept. This helps protect your capital from large drawdowns. For example, if you buy a stock at $100 and set a stop loss at $95, your position will automatically close if the price falls to $95, limiting your loss.

The importance of stop loss goes beyond just protection, it enforces discipline and consistency. Many traders lose money not because of bad entries, but because they hold losing trades for too long. A stop loss removes emotional decision-making and ensures you follow your strategy.
