Setting Stop-Losses and Take-Profits
How predefined exit levels work, and why deciding them in advance matters.
Jump to section
What to remember
- Stop-losses and take-profits are predefined exit levels decided in advance.
- Deciding levels in advance tends to reduce emotionally-driven decisions.
- Setting levels too tight or too loose both create real practical problems.
- Moving a stop-loss further away mid-trade defeats its original purpose.
What a stop-loss and take-profit do
A stop-loss is a predefined price level at which a position is closed to limit further loss. A take-profit is a predefined price level at which a position is closed to lock in a gain. Both are ways of deciding an exit in advance, rather than in the moment.
Why deciding levels in advance matters
Deciding exit levels before entering a position, while thinking clearly, tends to produce more consistent outcomes than deciding in the moment, when a fast-moving price and real financial stress can make emotionally-driven decisions more likely.
Practical considerations
- A stop-loss set too tight, relative to an asset's normal volatility, may trigger prematurely on ordinary price noise rather than a genuine trend change.
- A stop-loss set too loose may not meaningfully limit the loss it's intended to control.
- Many exchanges let you set these orders in advance so they execute automatically, without needing to actively watch the market continuously.
Moving a stop-loss further away mid-trade defeats its purpose
Widening a stop-loss after entering a position specifically to avoid taking a loss undermines the entire reason for setting it in advance — it reintroduces exactly the in-the-moment emotional decision-making a predefined stop was meant to avoid.
