Trailing Stop Loss: How It Works, With Examples

What is a trailing stop loss?

A normal stop loss stays where you put it. A trailing stop follows the price at a distance: for a long trade it rises as the price makes new highs; for a short it falls as the price makes new lows. It never moves against you. If the price turns and hits it, you are out.

Example. You buy at 100 with a 5% trailing stop, so the stop starts at 95. The price climbs to 120; the stop rises to 114 (5% below 120). The price then falls back and hits 114 — you exit with +14, having given back only part of the move.

Price line from 100 to a high of 120 and back to 114, with a 5% trailing stop stepping up from 95 to 114 where the trade exits at +14 — A 5% trailing stop: it only moves up, and the exit at 114 keeps most of the move from 100 to 120.

How to trail a stop: 5 common methods

1. Fixed percent or points

Keep the stop a set distance behind the best price (5%, 50 points). Simple, but the same distance can be too tight in a fast market and too loose in a slow one.

2. ATR (volatility)

Trail by a multiple of the Average True Range, e.g. 2 × ATR below the highest price. The stop gives more room when the market moves more.

3. Swing lows / highs

Move the stop to just below each new higher low (or above each lower high for shorts). It follows the market’s structure.

4. Moving average

Exit on a close below a moving average such as the 20 EMA. Smooth, but reacts later than a swing stop.

5. Breakeven at 1R, then trail

Move the stop to entry once the trade reaches +1R, then trail with one of the methods above. Removes the risk early, at the cost of more breakeven exits.

A worked example in R

A BTCUSDT long at 84,200 with the first stop at 83,600 risks 600 per coin — that is 1R. The trader trails below each new swing low:

BTCUSDT candlestick chart: long entry at 84,200, first stop 83,600, stop moved to 84,450, 85,050 and 85,850 below each new swing low, exit at 85,850 for +2.75R, and a fixed 2R target at 85,400 for comparison — The worked example: each new swing low lifts the stop. The trade exits at 85,850 (+2.75R); a fixed 2R target would have closed at 85,400.

Price makes a new swing low at	Stop moves to	Locked in
84,500	84,450	+0.42R
85,100	85,050	+1.42R
85,900	85,850	+2.75R

If the price then drops to 85,850 the trade closes at +2.75R. A fixed target at 2R would have closed at 85,400 for +2R — the trail kept the trade open for the rest of the move.

Pros and cons

Why traders use it

Lets big winners run, which is where most of the profit in trend trading comes from. Removes the urge to grab small profits. Rules are clear in advance.

What to watch

Too tight and normal noise stops you out early. It always gives back part of the move. On gaps the exit can be worse than the stop. Fees and slippage matter on tight trails.

Trailing stop orders vs trailing by hand

Some exchanges and brokers offer a trailing stop order that moves automatically by a set amount or percent. Others don’t support it for every product, so many traders trail by hand: after each candle closes they move a normal stop order to the new level. Either way, decide the rule before entering — a trailing stop you change in the moment is just another discretionary exit.

How a journal helps

Record each partial exit and where your stop finally was. Profit Prism Journal keeps every exit with its own R, so after a month you can compare: did trailing give you bigger average winners than fixed targets, and how often did it stop you at breakeven?

Frequently asked questions

What is a trailing stop loss?

A trailing stop loss moves with the price as a trade goes your way — up for a long, down for a short — and never moves back. If the price reverses and hits it, the trade closes, locking in part of the profit.

How does a trailing stop loss work?

You set a distance (a percent, points, an ATR multiple or a chart level). Each time the price makes a new best level, the stop moves to keep that distance; when the price comes back to the stop, you exit.

What is a good trailing stop percentage?

There is no single best value; it depends on the market’s volatility. Many traders use a multiple of ATR (for example 2–3 × ATR) or recent swing levels instead of a fixed percent.

Should I move my stop to breakeven?

Moving to breakeven at +1R removes the risk on a trade but also turns some would-be winners into breakeven exits. Test it on your own journal data before making it a rule.

Can I use a trailing stop in Indian F&O?

Some brokers offer trailing stop orders for some products; where they don’t, traders trail manually by moving a normal stop-loss order after each candle closes.
