In simple terms
Stopping out means exiting a position because the condition that limits loss or protects a result has occurred. The exit may be automatic through an order or manual under the trading plan.
Rule and order
A stop loss is the risk rule; a stop order is one tool for applying it. A conventional stop becomes market when triggered and favors execution rather than an exact price. A stop-limit imposes a price boundary but may leave the position open.
The journal should record intended level, trigger, filled price and quantity, slippage, and reason. This separates a correctly applied rule from an order-entry mistake or emotional exit.
Limit
The stop price is not a guaranteed execution price, and stopping out cannot remove gap or liquidity risk. Exiting at a loss also does not mean the stop was wrong; it must be assessed against planned risk.
