Trailing Stop

A stop that follows the price up and fires on the way down

A Trailing Stop is a sell order whose trigger level follows the market price upward. Instead of a fixed stop price, you set a trail percentage; the stop rides the price up as it climbs and fires only when the price retraces by your trail amount from its peak.

It's the "let winners run, but lock in gains" order — previously only available on centralized exchanges, now fully on-chain via the Epsilon Router.

Trailing stop

How it works

1. You place a sell order for a token and set Trail by — a percentage (e.g., 10%).

2. The order tracks the highest price observed since creation.

3. The Fires at level is always peak price × (1 − trail%), shown live in the form.

4. If price keeps climbing, the fire level climbs with it — it never moves down.

5. When price retraces to the fire level, the Matcher executes the sell at the best available route.

Creating one

1. Open app.alienbase.xyz/swap, pick the pair.

2. Order form → Pro → Trailing Stop.

3. Enter the amount to sell (25% / 50% / Max shortcuts available).

4. Set Trail by %. The form shows the current Market price and the resulting Fires at level.

5. Choose expiry (default 1 week) and slippage (default 0.5%).

6. Confirm in your wallet. The order appears under Open orders.

Choosing a trail percentage

• Tight trails (2–5%) lock in gains quickly but get stopped out by normal volatility — suited to stable pairs or short-horizon trades.

• Medium trails (8–15%) survive typical intraday noise on mid-caps.

• Wide trails (20%+) are for volatile small caps and memecoins, where 10% wicks are routine.

A useful rule: set the trail wider than the token's typical daily range, or ordinary chop will trigger the stop.
