Prow's Ladder bot is a combo bot: it opens a futures position, buys more as the price falls and sells in steps as it rises. A stop loss is always on.

How a Ladder earnsA coin at $198, six levelsPercent from the first order
One full cycle
+$34.93 before fees
The price dips to $188, then climbs past $212. $1,000 at 1x.
It is for a coin that dips and climbs back, and for a trader who wants to be in the market from the first minute. It is not a yield product: a Ladder earns when the price swings back up through its levels and loses when the price falls through them, and the stop loss decides how much. The bot runs on Prow's servers around the clock, so nothing has to stay open on your device.
The bot opens with a position, so the first rise already earns. When the price dips, it buys more at lower levels and sells each add one level higher, so every swing back up through two levels earns a step.
The first order is sold on the levels above the price, an equal share on each, not all at one target. The first sell that fills also starts the trailing stop.
The stop loss is required. After the first sell it follows the highest price at the distance it started at, in whole steps, and never moves back. When every step has sold, the bot can open again around the new price.
A Ladder, the kind of bot Bitsgap calls COMBO, is a futures grid that starts with a position. You set a price range and a number of levels. At the start the bot buys the first order at market, a share of your investment times your leverage (50% by default), and rests a sell on every level above the price: the take-profit steps. The rest of the money funds a buy on every level below the price: the adds. The builder lists them as Take-profit orders and DCA orders.
When an add fills, the bot places a sell one level higher for the same coins, and when that sell fills the buy comes back. The first order sells in equal steps as the price climbs. Each side has its own size: with half of the money on each, an add buys a few more coins than a step sells, because it sits at a lower price. The cover shows the example as a price axis: the steps above the price, the first order, the adds under it with the price each is sold at, and the stop that climbs with the sells, from $180 to $191.27; the table lists every order.
After the first sell fills, the stop starts to follow the price up. When everything above the range has sold, the bot waits and opens again around the price, up to a limit you sign. With Re-open after full profit off it stops.
Six levels of $4 between $188 and $212, drawn out
| Price | At the start | Coins |
|---|---|---|
| $212 | Take profit 3: sell | 0.82 |
| $208 | Take profit 2: sell | 0.82 |
| $204 | Take profit 1: sell | 0.82 |
| $198 | First order: buy at market | 2.45 |
| $196 | Add 1: buy | 0.87 |
| $192 | Add 2: buy | 0.87 |
| $188 | Add 3: buy | 0.87 |
| $180 | Stop loss: closes everything | All |
Each add is sold again one level up: add 1 at $200, add 2 at $196 and add 3 at $192, for $3.47 each before fees. The first order sells in three equal steps, +$24.51 in all.
A Ladder has a direction. It decides what the first order does and which way a trend hurts it.
The first order buys
The first order buys at market. The sells above the price take profit in steps, and the buys below it add when the price falls. The stop sits under the range and, once the first take profit has filled, follows the highest price up. The re-open limit is the Never re-open above price. A Long Ladder earns when the price swings back up through its levels and loses when it falls through them.
The first order sells
The first order sells at market and opens a short. The buys below the price take profit in steps, and the sells above it add when the price rises. The stop sits above the range and, once the first take profit has filled, follows the lowest price down. The re-open limit is the Never re-open below price. A Short Ladder earns when the price swings back down through its levels and loses when it keeps rising.
A Short Ladder loses when the price keeps rising; it is only available on the deepest markets. The review shows the same warning before you sign.
Four things, and nothing else. It never moves money, and its stop loss waits on the venue.
The first order buys at market: a share of your investment times your leverage, half by default. The bot then rests a sell on every level above the price, an equal share of the first order on each, and a buy on every level below it. The sells can only close what the bot holds. The ladder's orders are limit orders that rest on the order book, so they pay the maker fee.
Each buy that fills is an add: more coins at a lower price. The bot places a sell one level higher for the same coins, and when that sell fills, the buy comes back. It never adds margin: everything it opens fits in the investment and leverage you sign.
The first order sells one step at a time as the price climbs. The first sell that fills starts the trailing stop: it follows the highest price at the distance it started at, in whole steps of at least 0.5%, at most every 30 seconds, and never moves back. Each move is a line in the bot's Log. Buys within one step of the stop are cancelled.
When everything above the range has sold and the price is above it, the bot waits for the cooldown, 60 minutes by default, and opens again around the price with the same width, step and stop distance, at most three times a UTC day and never above your Never re-open above price. With Re-open after full profit off it stops. If you trade its market by hand or cancel one of its orders, it pauses and keeps its stop.
All three cases use one Ladder: $1,000 at 1x on a coin at $198, six levels of $4 between $188 and $212, with the stop at $180 and half of the money in the first order. The builder starts at 20 levels, so these steps are bigger than a default Ladder's; the arithmetic is the same.
+$33.98
A full cycle, after fees
The price dips to $188 and climbs back past $212. The three adds are sold one level up (+$10.42) and the first order in three steps (+$24.51). That is $34.93 before fees, less $0.95 to Hyperliquid and Prow.
−$76.54
If the price falls to the stop
The bot holds 5.06 coins at $194.91 on average, and the stop closes them at $180: $75.37 on the coins plus $1.18 in fees, before slippage.
−$21.95
If a climb to $209 turns back
On the way up five sells fill and the stop trails to $187.45. On the way down the bot buys four levels again, and the stop closes 4.19 coins: −$20.26 before fees, with $1.69 in fees.
Prices are before slippage, and the first order and the stop are taker orders. The climb that turns back is the example walked through the engine's own rules: the price dips to $188, climbs to $209 and falls to the stop. On Aster's USDT perps the base-tier maker fee is 0% and Prow's fee is 0.01%, so the same cycle costs less there. Your own fee tier may be lower than the base tier.
A run length (1 to 3 days, 3 to 15 days or 25+ days) fills most of them in from the coin's recent prices. Four set a Ladder apart, below; everything else sits under Manual adjustment and Advanced, and the docs explain every field.
Default: 20
How many steps the range is cut into, 6 to 40: the take-profit steps above the price and the adds below it. The builder calls the count DCA + grid levels, and its Grids slider shows the step and the minimum investment for each count. Geometric spacing, the default, keeps an equal percentage between levels, arithmetic an equal price.
Default: On
After the first sell fills, the stop follows the price at the distance it started at, in whole steps of at least 0.5%, at most every 30 seconds, and never moves back. Buys within one step of it are cancelled.
Default: 50%
30% to 70% of investment times leverage opens at the start, and the rest funds the adds. A bigger share sells in bigger steps and leaves less to buy dips with.
Default: On
When everything above the range has sold, the bot waits 60 minutes and opens again around the price, at most 3 times a UTC day and never above Never re-open above (the chart calls it Trailing limit), which starts at 1.5 times the upper price (a Short's: below). Off: the bot stops.
You need a Hyperliquid or Aster account linked in Prow with free margin for the Ladder. The bot cannot move funds, so deposit first. Bots run only on the markets on Prow's list, the ones with a deep order book, and one bot can run on a market on an account at a time.
The list shows ready setups for liquid coins: tap one and the builder opens with it filled in. Or press Set up myself and pick the market there.
The market is picked in the header, as on Trade: a perp on Hyperliquid or Aster, since a Ladder runs on futures only. Direction is Long, or Short on the deepest markets. Investment is what the bot may use: 25%, 50% and Max fill in a share of what is available. Leverage starts at 1x, and the bot never adds margin beyond what you set.
1 to 3 days, 3 to 15 days or 25+ days fill in a range, the number of levels and a stop fitted to the coin's recent prices. Under Manual adjustment you set them yourself: the Grids slider, the lower and upper price, the level spacing, the stop loss, Trailing stop, Breakeven after a take profit and Re-open after full profit with Never re-open above. The rest, from First order share to Max loss, is under Advanced.
Continue checks the settings: the minimum investment, the stop, the liquidation price. The review is named after your coin, like Start HYPE Ladder: Summary lists the investment, the range, the levels, the first order, the stop loss and the max loss, and Limits, Settings and Bot key list what you sign, every setting and what the key can do. Turn on the risk acknowledgement.
Before it starts lists the signatures it needs, up to three: Enable bots on Hyperliquid (or Aster) for the first bot on the account, Approve the Prow fee once, and Sign the bot's limits. Prow's servers refuse any order outside those limits. When the Ladder starts, Open bot shows its page.
The bot's page looks like Trade: the market's chart with the Ladder's levels and fills, and the bot's panel with its figures and its buttons. Open bot shows it when the Ladder starts, and My bots lists it after that.
Total PnL, with Profit taken, Unrealized, Today, APR (after a day), In the bot and Trades. Under it Settings lists the settings the Ladder runs with and links to Edit settings.
The chart shows the Ladder's orders and fills, its average entry and its stop loss, with the stop it started at drawn too once the trailing stop has moved it. The Position tab lists the size, entry, mark and liquidation price with how far away it is, and where the stop sits.
Orders lists what the bot has on the venue, each with its side, type, price, size, level and status, read-only: cancelling one elsewhere pauses the bot. Trades lists each completed pair with when it closed, its buy price, its sell price, its size, its profit and its fees, and Log lists every fill and each time the stop moves.
Pause cancels the Ladder's orders and keeps the position and the stop. Edit changes the name, the take profit and the trailing take profit; the range, the levels, the leverage and the stop loss are part of the limits you signed, so to change them you use Copy settings and start a new Ladder. Stop asks what happens to the position: Close the position at market, Keep the position with its stop or Keep the position without a stop.
The limits last 30 days at most. From 3 days before they end the page shows Renew limits: one signature keeps the bot running with the same settings. The Prow Bots key lasts 30 days too, and is renewed with one signature. If either lapses, the bot cancels its orders an hour before and pauses, with its stop kept on the venue.
Your money stays in your own account. The venue, not Prow, stops the key from withdrawing: it has no withdrawal permission. Prow's servers check every order against the limits you sign, and if they go down, the Ladder's stop stays on the venue. More in the Prow Bots key.
The check against your limits runs on Prow's servers, not on the venue. On Aster the key only works from them.
A Ladder earns in steps and can give them back at once. The stop loss is what caps it.
Every add fills, so the bot holds the most coins it ever holds, at the lowest prices, and the stop closes them at a loss that takes about two full cycles of profit to earn back in the example. A Short Ladder is the mirror: it loses when the price keeps rising.
On the way down the bot buys the levels it sold again, and the trailing stop sits as far under the high as the stop started under the price, 9.1% in the example, so a climb that turns back can end at the stop in a loss. The stop moves up with the price, but it does not promise a gain.
A Ladder trades often, and each fill carries the venue's fee plus Prow's on every perp fill. A full cycle in the example has 10 fills and costs $0.95 of its $34.93. The first order, the stop and a re-open are taker orders and cost more. While it holds a position it also pays or collects funding, every hour on Hyperliquid.
Gains and losses both grow with leverage, and liquidation comes closer. The builder checks that liquidation would come after your stop with every level filled, and refuses the Ladder if it could not. 1x is the default, 3x the most on most markets.
A combo bot runs DCA and grid logic on one position: it adds to the position when the price moves against it, and takes profit in steps when the price moves back. Bitsgap calls its version COMBO; Prow calls it the Ladder bot. You set a price range and a number of levels. At the start the bot buys a first order at market, 50% of your investment times your leverage by default, and rests a sell on each level above the price and a buy on each level below it. A buy that fills is an add: the bot places a sell one level higher for the same coins. The first order sells in equal steps as the price climbs, and the first sell that fills starts a trailing stop. Prow's Ladder runs on Hyperliquid and Aster perps, with a stop loss that is always on.

A futures grid bot keeps one range and the same stop: it buys and sells the same coin size on every level, and when the price leaves the range it keeps running or stops, as you choose. A DCA bot opens a deal with a base order, adds extra buys at set distances and sells the whole deal at one take profit above the average price, or in two or three steps under Advanced. A Ladder sits between them. Like a DCA bot it opens with a position and adds on the way down, and like a grid it sells in steps on fixed levels. Unlike both it moves its stop up after the first sell and, once everything above the range has sold, opens again around the new price. It has no trigger price, no range exit and no Neutral or spot version.

Sometimes, and only while the price swings. In the page's example a full cycle earns $33.98 after fees on $1,000: the price dips to $188, filling three adds, and climbs back past $212. When the price falls through the ladder instead, the stop closes the bot at a loss of $76.54, about two full cycles of profit. A climb that turns back can lose too: the bot buys its levels again on the way down, and in the example a climb to $209 followed by a fall ends at the stop for −$21.95. A Ladder has no edge of its own: it is a way to be in the market with a plan for dips and rises, not a source of income.

A price range (a lower and an upper price), the number of levels (6 to 40), the level spacing (arithmetic or geometric), an investment, a direction (Long, or Short on the deepest markets), leverage and a stop loss. The builder starts with the range 10% either side of the price, 20 geometric levels, 1x and a stop 5% below the range. A run length (1 to 3 days, 3 to 15 days or 25+ days) fills the rest in from the coin's recent prices. Under Manual adjustment you can turn the trailing stop and Re-open after full profit on or off, set Never re-open above and turn on Breakeven after a take profit. Under Advanced are the First order share (30% to 70%, 50% to start), the wait before a re-open, the re-opens per day, a take profit, a trailing take profit and the max loss.

The stop loss starts where you put it, under the range. When the first sell fills, it starts to follow the price: it sits as far under the highest price as it started under the start price (9.1% in the example, $198 to $180), moves up only in whole steps, at least 0.5% and at most every 30 seconds, and never moves back. Buys that would sit within one step of the stop are cancelled. It limits how much a reversal can cost after a climb, but it does not lock in a profit: in the example a climb to $209 that turns back ends at the stop, near $187.45, for −$21.95.
When every level above has sold and the price is above the range, the bot waits for the cooldown (60 minutes by default) and, with Re-open after full profit on, opens again around the price with the same width, step and stop distance. It does so at most 3 times a UTC day and never past your Never re-open above price, which is part of the range you sign. With Re-open off, it stops. When the price falls under the range instead, every add has filled and the stop loss closes the bot: in the example 5.06 coins bought at $194.91 on average close at $180 for a loss of $76.54 with fees.
No. It trades with a key called Prow Bots. The key can place and cancel the bot's orders and set leverage, but it cannot withdraw, send funds to another address or account, or approve another key. On Aster it can also move funds between your own spot and futures balances, which Prow's servers never do for a bot. Prow's servers check every order against the limits you sign for the bot and refuse the rest, and the bot's stop loss rests on the venue. The key expires after 30 days unless you renew it with one signature, and on Aster it only works from Prow's servers.

The venue's fee on every fill, plus Prow's fee on every perp fill the bot makes: 0.025% on Hyperliquid and 0.01% on Aster. A Ladder's resting orders pay the maker rate; the first order, the stop and a re-open are taker orders and cost more. In the example a full cycle has 10 fills and costs $0.95 on Hyperliquid at the base tier. There is no subscription. Prow's 0% launch fee, until Dec 31, 2026, is for orders you place yourself in the app: a bot pays the fee from its first fill. A futures Ladder also pays or collects funding while it holds a position.

Bitsgap's COMBO runs in Bitsgap's service on a key you create on an exchange: on activation it uses 50% of your investment times your leverage, it may place extra orders with up to 1.5 times more margin when the price leaves the range, it takes leverage up to 10x, and its stop loss is trailing by default. Prow's Ladder runs on your own Hyperliquid or Aster account with a key that cannot withdraw. Its first order is 30% to 70% of your investment, 50% to start, it never adds margin beyond the investment and leverage you sign, and leverage is 1x to 3x, or 5x on the deepest markets. Bitsgap sells plans and offers a 7-day trial; the Ladder has no subscription. Checked on Nov 6, 2026.

Bots are switched on account by account. Any Prow account can open the builder, but starting a Ladder needs bots switched on for your account. If they are not, Continue stays off and nothing is signed or placed. You also need a Hyperliquid or Aster account linked in Prow with free margin for the Ladder.
