Trade math
Calculators
Three small tools — PnL, target price, liquidation price — that run in your browser. No wallet required.
All math runs client-side; entries you type aren't sent anywhere. The liq calc uses HL's per-asset max leverage (fetched once via /info meta) to approximate the maintenance margin fraction as 1 / (2 × maxLeverage) — that's HL's documented convention for most perps. Once a real position opens, the canonical liq price comes from clearinghouseState; this calc is for pre-trade sizing.
