Stop-loss and take-profit: triggers are not guaranteed fills

What a stop does

A stop specifies a trigger and the order instruction activated when its reference condition is met. A long-position sell stop commonly sits below entry; short-position exit direction is reversed. Stop-market and stop-limit behave differently. The term stop-loss alone does not establish reference price, guaranteed availability or a maximum realized loss.

What a take-profit does

A take-profit expresses an intended exit around a favorable price condition. Depending on the venue it can be a resting limit or a conditional order. A chart touching a level does not prove your entire quantity executed. Available depth, queue priority, trigger reference and order constraints determine actual fills.

One example with three prices

Hypothetical long entry $100, stop trigger $95. A market-style exit fills at $94.50 during a fast move. Price loss is $5.50 per unit before costs, not the planned $5. A stop-limit with a $94.80 floor might instead remain unfilled at the available $94.50 bid. These are distinct execution risks, not guaranteed outcomes.

Reference prices and liquidation

A mark-price liquidation condition can be met before a last-price stop triggers. A triggered order may still need time and liquidity to execute. Maintenance tiers and cross-margin conditions can change independently. A stop positioned on a chart is therefore not proof that forced liquidation cannot happen.

Paired exits and remaining orders

If profit and stop exits are linked through a venue’s OCO or position-specific feature, one may cancel the other under those rules. Two independent orders do not automatically cancel each other. Remaining quantities, partial fills and reduce-only conditions matter; otherwise a surviving order can create unintended reverse exposure.

Plan, calculate and reconcile

Record the trigger basis, execution type, quantity, limit and fees for a hypothetical exit. Use position sizing for the modeled price-distance loss and the cost calculator for additional expenses. After an execution, reconcile actual average price and remaining orders. This guide explains mechanisms, not where to place an exit or which trade to choose.
