Stop-Loss

What is a stop-loss?

A stop-loss is an instruction attached to an open trade telling the broker to close it automatically if the price moves against the trader to a specified level. It removes the need to watch every trade constantly, and it puts a hard ceiling on how much a single position can lose.

Stop-losses are placed at the same time a trade is opened, based on technical levels — such as below support on a long trade — or on a fixed pip or percentage distance tied to the trader’s position sizing.

A worked example

A trader buys GBP/USD at 1.2700, expecting the price to rise. They set a stop-loss at 1.2670, 30 pips below entry. If the trade moves as expected, the stop simply sits unused. But if the market reverses and falls to 1.2670, the position closes automatically at (or close to) that price, limiting the loss to roughly 30 pips — instead of the trader hoping for a turnaround while losses grow to 100 pips or more.

Why it matters

A stop-loss is one of the simplest and most effective risk management tools available, because it enforces discipline even when emotion would otherwise push a trader to “wait it out.” It works hand in hand with a take-profit order to define both sides of a trade’s risk-reward ratio before the trade is even placed. A trailing stop is a variant that moves the stop level as a trade becomes profitable, protecting gains as well as capping losses.

Note that in fast-moving or illiquid markets, a stop-loss can still experience slippage, executing at a slightly worse price than the level set — brokers with reliable execution and, where offered, negative balance protection help limit this risk further.

Quick recap

• A stop-loss automatically closes a losing trade at a preset price, capping the loss.
• It is set at trade entry, based on technical levels or a planned pip/percentage distance.
• It removes emotion from exit decisions and is a core building block of risk management.
• Execution can still slip in volatile conditions, though it remains far safer than trading with no stop at all.
