What is a Stop Loss?
A stop loss is a pre-set order that automatically sells a security when its price falls to or below a specified level (for long positions) or rises to or above a specified level (for short positions). It acts as an insurance policy, limiting the maximum loss on any single trade.
Stop losses remove emotion from exit decisions and ensure that small losses don't become large ones. They're a fundamental component of any disciplined trading or investing strategy, allowing traders to define their risk before entering a position.

Stop Loss Risk Disclaimer
While stop losses are essential risk management tools, they do not guarantee against losses. Stop orders may experience slippage, where execution occurs at prices worse than the stop level, especially during volatile market conditions or gaps. Stop losses cannot protect against overnight gaps or limit-down scenarios. Market conditions can change rapidly, and stop orders may not always execute as expected. Past performance and back-testing results do not guarantee future effectiveness. Always consider your risk tolerance and investment objectives. Consult with qualified financial professionals before implementing any trading strategy involving stop loss orders.
