How Trailing Stop Losses Work
A trailing stop loss is a dynamic order that moves with the market price, automatically locking in profits as a stock rises. When the price moves in your favor the stop level trails behind at a fixed percentage distance. If the price reverses and hits the trail level, the position is closed, securing the accumulated gains. Example: entry at $100, current high $150, 10% trail triggers at $135. The trigger table shows intermediate levels at 5%, 10%, 15%, 20%, and 25% retracements from the high. Percent trail scales with price; dollar trail fixed for low priced stocks with wide tick sizes.
This calculator generates a table of trigger prices at 5, 10, 15, 20, and 25 percent retracement levels from the current high. You can see exactly where your stop would trigger at each level, helping you choose the right trail percentage for your trading style and the asset's volatility. Wider trails suit volatile small caps while tighter trails fit large cap trend followers. Review average true range before picking a single trail percentage. Combine with position sizing so initial risk budget still respected before trail ratchets upward. Short positions mirror logic with stop above price falling as new lows print.

Trail Level = Current Highest Price x (1 - Trail Percentage / 100)
Distance from High = Current High - Trail Level
Trigger Price at N% = Current High x (1 - N / 100)

FAQ
What is the ideal trailing stop percentage?
There is no single ideal percentage. It depends on the asset's volatility and your time frame. Day traders often use 1 to 3 percent trails, swing traders use 5 to 10 percent, and long term investors may use 15 to 25 percent. Review the asset's average true range to calibrate your trail. Day traders use 1 to 3 percent trails on liquid large caps. Swing traders often choose 5 to 10 percent on multi day holds. Gap down through stop may fill below trigger price because exit becomes market order.
Does a trailing stop guarantee my limit price?
No. In fast moving markets the actual fill price may be worse than the stop price due to slippage. This is more common in volatile or thinly traded stocks. Market orders at the stop level execute at the next available price which can differ from the trigger price. Gap downs through the trail level fill at the next trade price, which can be far below the trigger during earnings gaps. Percent trail scales with price; dollar trail fixed for low priced stocks with wide tick sizes.
Can I use trailing stops in cryptocurrency markets?
Yes many crypto exchanges support trailing stop orders. Due to extreme volatility in crypto markets consider using wider trail percentages (10 to 20 percent) to avoid being stopped out by sudden flash crashes that quickly reverse. Crypto flash crashes frequently hit tight trails before recovering. Many crypto traders use 15 to 20 percent trails on spot positions. Combine with position sizing so initial risk budget still respected before trail ratchets upward. Short positions mirror logic with stop above price falling as new lows print.
How is a trailing stop different from a regular stop loss?
A regular stop loss is a fixed price that does not change. A trailing stop moves up (for long positions) as the market price rises, continuously protecting profits. The regular stop protects a fixed amount while the trailing stop protects a floating amount that grows with the position. Regular stops stay fixed at entry minus a dollar amount. Trailing stops ratchet up with new highs, locking progressively more profit. Short positions mirror logic with stop above price falling as new lows print.
What happens if the stock gaps below my trail level?
If the stock opens significantly lower than the previous close and gaps below your trail level, the stop becomes a market order and fills at the next available price. This is known as gap risk and is unavoidable with any stop loss strategy. Weekend gaps in forex linked sessions can trigger trails Monday open far from Friday close.
