Trailing Stop

In simple terms

A trailing stop is like a safety net that automatically moves up as your investment gains value, protecting your profits if the price suddenly drops. Once you set it, you don't have to watch the market constantly—it will sell automatically if things turn against you.

Definition

Dynamic stop that moves with price action, locking in profits as the price moves in your favor.

In depth

A trailing stop is a conditional order type that maintains a fixed percentage or absolute price distance below the current market price, dynamically adjusting upward as the asset appreciates but remaining stationary if price declines. When the market price falls to meet the trailing stop level, the order triggers a market or limit sell execution, effectively locking in gains while allowing for continued upside participation. This mechanism is particularly useful in volatile markets where manual stop-loss placement becomes impractical, as it responds to real-time price action without requiring trader intervention or emotional decision-making.

How does Trailing Stop work?

You define a distance from the market price, either a percentage or a fixed amount, rather than a fixed trigger. For a long position the exchange records the highest price reached since the order was placed and keeps the trigger that distance below it. When price rises, the trigger ratchets upward with it. When price falls, the trigger stays put. Once price falls by the full trailing distance from the recorded high, the order triggers and executes like a stop-loss. The trigger only ever moves in one direction.

An example

Illustrative figures only. Someone holds a coin bought at $100 and sets a 10 percent trailing stop, placing the initial trigger at $90. Price rises to $140, so the trigger ratchets to $126. Price then falls to $126 and the order triggers, closing the position roughly $26 above the entry before fees. Had price fallen straight from $100 without rising, it would have triggered at $90 instead.

Figures are illustrative only.

What beginners get wrong

• A trailing distance set too tight gets hit by ordinary intraday noise, closing a position during a pullback rather than a real reversal.
• The trigger never moves back down, so a trailing stop cannot be used to give a losing position extra room after it is placed.
• Percentage and fixed-amount trailing behave very differently as price changes; using the wrong one is a frequent setup error.
• Trailing stops still execute as market orders on most venues, so the same slippage risk as a plain stop-loss applies at the fill.
