Stop Loss
An order that automatically closes a trade at a specified loss level.
Full Definition
A stop loss is a predetermined price level at which your trade automatically closes to limit losses. It is widely considered the single most important risk management tool in trading. Setting stop losses protects your capital, removes emotion from exit decisions, and ensures no single trade can deal a catastrophic blow to your account.
Placement matters as much as having a stop at all. Common techniques include placing stops below the most recent swing low for long trades (above swing high for shorts), beyond a meaningful support or resistance level, or at a multiple of Average True Range (ATR) to respect natural volatility. A stop placed too tight will be hit by normal market noise, while a stop placed too loose risks larger losses than the setup justifies. Professional traders size positions based on stop distance rather than choosing a stop distance to fit a preferred position size.
For example, if you have 1 standard lot on EUR/USD at 1.0850 with a 40 pip stop loss at 1.0810, your maximum loss is about $400. If the trade moves against you and hits the stop, the position closes automatically at 1.0810, saving you from watching the price fall further. If the trade succeeds and you take profit at 1.0930, you gained 80 pips, or roughly $800, a 1:2 risk-reward.
In copy trading, every signal from a well-designed strategy includes a stop loss. SteadyFlowFX's 9 algorithms attach stop losses to every trade, and those stops are replicated on subscriber accounts to maintain the same risk profile. The verified Myfxbook 34.2 percent max drawdown depends on stops consistently capping per-trade losses. Subscribers should never manually remove or widen copied stop losses because that breaks the risk mechanics that produce the 1.73 profit factor and 71.3 percent win rate published in the track record.
