Trailing stop (Aster)

A trailing stop follows the price as it moves in your favor and stays a fixed distance behind it. When the price turns and falls back by that distance, the stop closes the position at market.

For a Short it works the other way: the stop follows the lowest price and fires when the price rises by the distance.

Aster only

Trailing stops exist on Aster positions. Aster runs them on its own servers, so they keep working when Prow is closed.

Hyperliquid has no trailing stop. So the TP/SL window of a Hyperliquid position has no trailing stop row. Prow does not imitate one from the app, since it would stop trailing whenever the app is closed. Use a stop loss at Breakeven or a take-profit ladder instead.

Set a trailing stop

1. Open the TP/SL window of an Aster position

   From the TP/SL column of Trade's positions panel, TP/SL on a position card, or TP/SL on the position itself. Tap Advanced: Trailing stop is under Stop loss.

2. Turn on Trailing stop

   Flip the switch, or tap a preset: 0.5%, 1% or 2%.

3. Set the Distance

   How far the stop stays behind the best price, in %. From 0.1% to 5%, in steps of 0.1%.

4. Set an activation price (optional)

   The From field. Leave it empty to start trailing from the current mark right away. Enter a price to start trailing only once the mark reaches it. For a Long it must be above the mark, for a Short below.

5. Check the line under the fields and save

   It reads, for example: "Closes the position if price falls 1.0% from its high. Stop now at 592.42, −$70.08". Tap Save.

Good to know

• It triggers on the mark price and closes the whole position at market, reduce-only.
• It works alongside your stop loss. Whichever fires first closes the position.
• Changing it re-arms it. Aster cannot edit a trailing stop, so Prow replaces it. The new one starts trailing again from the current mark, not from the old high. The window says so: "Saving replaces the trailing stop: it starts trailing again from the current mark."
• It counts toward Aster's limit of 10 trigger orders per market, together with TP levels and stops.
• After the position closes, Prow cancels a leftover trailing stop while the Trade screen or the position is open. See After the position closes.
