Copy trading on Hyperliquid: how it works and what to check
Every Hyperliquid account is public, which makes copying possible. It does not make it simple. This is what happens between a trader’s order and yours.
In private testing: the trading engine is not live yet. The console you can open today shows sample data and nothing is traded. These pages describe how Helmsman is built to work.
Why copying is possible at all
On Hyperliquid, anyone can read any address: positions, size, entry price, leverage. A copy tool watches an address and reacts. Nothing is shared by the trader and nothing needs their consent.
Two ways to copy
Order-by-order copying repeats each of the trader’s orders at a scaled size. It breaks easily: a missed order, a partial fill or a position the trader held before you started leaves you permanently out of step.
Position-ratio copying looks at where the trader is and moves you to the same place in proportion. A missed step corrects itself on the next change. Helmsman works this way.
Custody: who holds the funds
Some products have you deposit into a vault run by the trader or the platform. Others trade inside your own account using an API wallet that cannot withdraw. The second kind cannot run off with your funds; it can still lose them by trading.
What it costs
Add up the exchange’s trading fee on every fill, the tool’s own fee, and funding. A trader who is in and out many times a day can be ahead on paper while a follower paying fees on every turn is not.
Questions to ask any copy tool
- Can the key it uses withdraw? On Hyperliquid an API wallet cannot.
- What stops it when things go wrong — and does that run separately from the part that trades?
- What happens to my open positions when I pause or stop?
- Is the fee stated as money, and can I see what I have paid?
- How are the traders chosen, and is past performance being presented as a promise?
