Hypurr Desk is a trading terminal for Hyperliquid perpetuals that runs entirely in your browser. You decide how much one trade may lose and where the stop goes; the desk works out the size and places the order with its stop and target on the exchange.
What it adds
- Size from the stop. Type a risk as a percent of your account and a stop. The size makes the loss at the stop equal that risk, fees included. See Risk sizing.
- Stops that outlive the tab. Stop losses, take profits and trailing stops are trigger orders on the exchange, so they keep working with the page closed.
- Orders on the chart. Drag a stop, a target or a resting entry to move it. A new stop is placed before the old one is cancelled.
- Trailing stops in R. Start and trail distances are multiples of the trade's risk.
- Review built in. A daily P&L calendar, R-multiples, expectancy and a trade journal with notes, tags and chart images.
- More than crypto. Stocks, commodities, indices, FX and pre-IPO markets sit in the same picker as crypto. See Markets.
How it runs
The site is a set of static files. Once loaded, the page talks straight to the exchange's public API and websocket. No Hypurr Desk server handles your trading, and there is no sign-up or account with us: your wallet's address is your trading account.
Your wallet signs one approval for a trading key that the browser generates and keeps. That key signs your orders afterwards, so placing, moving and cancelling orders needs no wallet pop-ups. It can trade, but it cannot withdraw or transfer funds; deposits and withdrawals are always signed by your wallet. See Wallets and the trading key.
Settings, presets, watchlists, journal notes and the risk records behind R-multiples live in this browser's storage. Nothing is synced between browsers or devices.
What it costs
The exchange charges its own trading fees. Hypurr Desk adds a builder fee of 0.025% of each order's value, which you approve once when you enable trading. The ticket shows the fee before you place an order. See Fees.
An independent project
Hypurr Desk is not affiliated with the exchange. Perpetual futures can lose your money quickly; read Security and risk before you trade, and start with small sizes.
