What Is a Stop-Loss Order?
A stop-loss order is an instruction to your broker to automatically sell a security when it drops to a specific price, limiting your potential loss. For example, buying at $50 with a stop-loss at $45 caps your maximum loss at 10%.
How Stop-Loss Orders Work
A stop-loss order sits dormant until the specified trigger price is reached, at which point it becomes a market order and executes at the next available price. For example, if you buy a stock at $100 and set a stop-loss at $90, the order activates if the stock drops to $90 — automatically selling your position to prevent further losses.
There are variations, including the stop-limit order (which becomes a limit order instead of a market order when triggered) and trailing stop-losses (which automatically adjust the trigger price upward as the stock rises, locking in gains). In fast-moving markets, a stop-loss may execute at a price slightly below your trigger price due to slippage.
Why Stop-Loss Orders Matter for Your Financial Goals
Stop-loss orders are one of the most important risk management tools available to traders. They enforce discipline by automatically exiting losing positions before emotions take over. Without stop-losses, traders often hold losing positions too long, hoping for a recovery that may never come — a behavior known as "loss aversion."

Key Takeaway
A stop-loss order is your safety net. It automatically exits a losing trade at a predetermined level, protecting your capital from catastrophic losses.

Market Order
A market order is an instruction to buy or sell a security immediately at the best available current price. It prioritizes execution speed over price control. In liquid markets, it typically fills within seconds near the last quoted price.
Leverage
Leverage is the use of borrowed capital to control a larger market position than your own funds would allow. For example, 10:1 leverage lets you control $10,000 with just $1,000. It amplifies both gains and losses equally.
Technical Analysis
Technical analysis is a method of evaluating securities by analyzing price charts, trading volume, and statistical indicators to identify patterns and predict future movements. Unlike fundamental analysis, it focuses entirely on price action rather than company financials.
