Tools & bots
Algorithms that place orders for you, the scalper’s keys, and the bots RXN runs. What is not there is said plainly at the end.
| Tool | What it does | RXN fee | Where |
|---|---|---|---|
| TWAP | Hyperliquid’s own: one big order in slices over time | 0 | Live |
| Chase | A post-only order that follows the best price | 0.01% | Live |
| Scale | A ladder of post-only orders over a price range | 0.01% | Live |
| Trailing stop | Hyperliquid’s own: a stop that follows the price | 0 | Live |
| TP/SL ladder | Several take-profits and stops on one position | Close rate | Live |
| Flatten · Flip · Breakeven | One-key position tools | Order rate | Live |
| Grid | A bot that buys low and sells high between two prices | Maker + 0.01% | Practice |
TWAP#
TWAP splits one large order into slices over 5 minutes to 7 days: a slice every 30 seconds, each at the market within 3%. It is Hyperliquid’s own algorithm, so it keeps running when you close RXN. Least size $100. Each slice pays Hyperliquid’s taker fee; RXN takes nothing on TWAP.
Chase#
Chase places a post-only order at the best price and moves it every second as the book moves, so you get in at the top of the book as a maker instead of paying to take. You can cap how far it may follow, and tell it to take the rest at the market after 30 seconds, 2 or 10 minutes. It runs while the page is open; up to 3 at a time.
Scale#
Scale lays a ladder of 3, 5 or 10 post-only orders (up to 50) between two prices, even or rising in size, each at least $10. Good for building a position into a range.
Trailing stop#
A stop that follows the price by a distance you set (up to 50%) and closes the whole position when the price turns. It is Hyperliquid’s own order, reduce-only, with no RXN fee.
Position tools#
- TP/SL ladder — up to 5 take-profits or stops on one position, their shares adding to 100%.
- Breakeven — moves the stop to your entry plus both fees.
- Flatten — stops chases, closes at the market, cancels the rest.
- Flip — one market order of twice the size: long becomes short.
- Close a share — 25%, 50% or 75% in one tap.
Hotkeys and the scalping desk#
The Scalp layout puts the scalper’s desk in place of the book: the book at Hyperliquid’s own tick with trades at each price, the visible depth, a tape of large trades, and a chart of bars by trade count. Hotkeys are off until you switch them on and send only with one-click:
| Key | Action |
|---|---|
| B / S | Chase buy / chase sell |
| C | Stop the chase |
| F · R · E · H | Flatten · flip · breakeven · close half |
| X | Cancel the market’s orders |
| Shift B / Shift S | Market order on the scalp desk (refused if the book is older than 1 second) |
| Shift C · Shift X | Close · cancel all |
Scalp Guard slows you down when it matters: at most 30 orders a minute, a 5-minute pause after 3 losses in a row, no order into a spread over 0.1%.
Grid#
The grid bot lays lines between two prices with an order of the same size on each. A long grid buys at a line and sells what it bought one line up; a short grid does the opposite. You choose 3 to 41 lines, arithmetic or geometric spacing, and leverage 1×, 2×, 3× or 5×, isolated. It stops itself when the price leaves the range, at a loss budget, at a floor of free margin, or when you press Stop grid. The result counts closed pairs, the open position at mark price, funding and every fee.
Request budget#
Hyperliquid limits how many orders an address may send: one request per 1 USDC traded, plus 10,000, then one every 10 seconds. Algorithms spend that budget, so RXN keeps a reserve of 200 requests for Guard and Panic: a way out always has room.
Bots on RXN#
- AI agents — bots that trade your account within a budget you sign, from the agent market or your own through MCP (early access).
- Telegram bot — as it ships on rxn.gg/apps: alerts (Guard, liquidation risk, price, funding, listings) and links such as
/long BTC 50 5xthat open a filled-in ticket on rxn.gg, which your own wallet signs. It holds no key and trades nothing by itself. - Grid bot — above.
- Alerts — on this device: Guard fired, liquidation risk, a price you set (up to 20), funding against you.
RXN is software, not advice. Nothing here promises a profit. Trading perps can lose you more than you expect.
