The netting problem
Hyperliquid nets positions within an account. If a trend follower is long a market while a mean-reversion leader is short it, a single shared account holds nothing at all — while both leaders continue to pay fees and both signals continue to be generated.
Worse, the netted account produces no attributable result for either leader, which destroys the data scoring depends on. Isolation is not a convenience feature; it is the precondition for measuring anything.
- One sub-account per leader keeps opposing positions live and separable.
- Per-leader PnL remains attributable, so scores stay meaningful.
- Margin and liquidation risk stay contained within each sub-account.
- Replacement affects one sub-account, not the whole book.
