Mental model
The core idea behind stop-loss orders
A stop-loss is a preplanned exit for when a trade is wrong. It turns a vague hope into a defined maximum loss before volatility and emotion start making decisions for you.
In Trading & Investing Strategies, stop-loss orders is a foundation the later lessons build on, so it is worth getting exactly right.

Mechanics
How to reason about stop-loss orders
A stop can be placed at a technical invalidation level, a percentage loss, or a volatility-based distance.
Market stops improve exit certainty but may slip.
Limit stops control price but may not fill in fast moves.
The reason these steps matter in practice is simple: a stop-loss auto-exits to cap a loss.

Example
Stop-Loss Orders, applied
A breakout trader might place a stop below the breakout level. If price falls back into the old range, the trade idea is no longer valid.
If the example only works with these exact details, you have memorised a case rather than learned stop-loss orders.
Ask what you would need to see on screen or on chain to trust a stop-loss orders outcome before you act on it.
Common mistakes
How stop-loss orders trips learners up
Moving the stop farther away after price moves against you usually changes risk without changing the original thesis.
Catch the stop-loss orders version early by asking which evidence would prove the claim, then actually looking for it.
Most costly stop-loss orders errors are not exotic; they are this ordinary shortcut repeated under time pressure.
Risk notes
Before you rely on stop-loss orders
Stops can be triggered by wicks, gaps, low liquidity, or liquidation cascades, especially with leverage.
Risk in stop-loss orders grows when markets move fast, liquidity thins, or an interface hides the warning that actually matters.
None of this means avoid stop-loss orders; it means using it with eyes open and a clear exit if you are wrong.
- Define invalidation.
- Choose stop type.
- Accept slippage in fast markets.
