A static ladder eventually gets left behind by the market. Trailing lets the window follow price — one direction slides for free, the other needs capital.

The two kinds of trailing

Every trail option is one of two mechanically different things, and confusing them is the source of most trail-related surprises:

SLIDE (free)
The window moves in the direction the grid profits from. The far rung is released and a new near rung is . Net capital unchanged. Long → trail up. Short → trail down.
EXTEND (costs capital)
The window grows in the adverse direction. New rungs are beyond the existing ladder and nothing is released. Requires new capital. Long → trail down. Short → trail up.

Trail up (on a long grid) — sliding

Price rises: the bottom rung is released and a new rung appears at the top.

As price climbs away from the ladder, the deepest rung becomes irrelevant — it is so far below the market it will not fill this cycle. Trail-up cancels it and re-deploys the freed capacity as a new rung just under the current price, so the grid keeps trading the range it is actually in.

  • No new capital: capacity is recycled, not .
  • Triggered when price exceeds the top of the window plus the .
  • The released rung's idle is retired so it cannot re-place itself later.

Trail down (on a long grid) — extending

beforewindow fullprice fallsafternewwindow extends down — needs capital
Price falls through the ladder: new rungs are appended below, funded by new capital.

When price runs below the deepest rung the grid is fully deployed and out of ammunition. Trail-down adds levels beneath the window — but only up to max_capital. This is why raising with trail-down enabled immediately deploys the increase downward.

!
Caution:Extending downward is averaging into a losing move. It is the call when you believe the is in a range and this is an excursion; it is exactly wrong in a structural downtrend. Pair it with a or a hard capital ceiling.

Selecting both

The two are independent and can both be on. That gives a window that follows price up for freeand extends down when funded — the most adaptive configuration, and the most capital hungry. The filters the list to the that make sense for your direction and for trail capital only when an extending is selected.

Trail init lots

Opening position — init lots × market fill @ baseL0target 1 · +1 × target%T1target 2 · +2 × target%T2target 3 · +3 × target%T3
With trail init lots, targets beyond the first open new levels instead of plain exits.

Normally every init target is a plain take-profit on the opening position. With trail enabled, the behaviour becomes sequential: target 0 restocks level 0, while target 1, target 2 and so on open new above the base (at −1, −2 … for a long grid) instead of simply closing out.

The effect is that a strong move up converts the opening position into ladder structure above the base, so the grid keeps having something to sell into continued strength rather than exiting entirely and going flat.

ℹ
Note:The option only appears when the sliding trail mode is selected for your direction (trail-up on a long grid, trail-down on a short one), because that is the only context where levels beyond the base make sense.

Auto increment and rebalance

Auto increment
Lets the grid grow its level count over time as profits accumulate, within the capital ceiling.
Rebalance
Periodically gaps in the ladder and re-extends it, healing a grid whose rungs were cancelled or skipped. Also available as a manual command from the terminal's Controls tab.
