Why PerpWise

Built for traders, not for harvesting data

Live market prices

Pull real-time prices straight from the market so your entry, liquidation and P&L match what you'd actually trade.

Your inputs stay private

No account, no tracking of your trades. Every calculation runs in your browser — only public price data is fetched.

Exchange-accurate math

Liquidation and leverage use the same isolated-margin model the major futures exchanges apply.
