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.

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:

KeyAction
B / SChase buy / chase sell
CStop the chase
F · R · E · HFlatten · flip · breakeven · close half
XCancel the market’s orders
Shift B / Shift SMarket order on the scalp desk (refused if the book is older than 1 second)
Shift C · Shift XClose · 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 5x that 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.
