Prices & price gap
The perp price comes from Hyperliquid. The futures price is an estimate using the premium below, initially 0%, not a CME quote. Edit either price to override the feed; the other price follows the selected premium.
For example, 1% means futures price = perp price × 1.01. Negative values mean futures trade below the perp. Changing the premium keeps the last price you edited fixed.
Equal dollar exposure matches sensitivity to a percentage move, not necessarily the same point move. Fractional futures contracts are comparison equivalents; actual futures orders use whole contracts. Fees and funding are excluded.
Why can the prices differ?
Perpetuals and dated futures can trade at different prices. This tool lets you model that gap as a percentage instead of treating their prices as unrelated inputs. With no gap, one NQ contract equals 20 XYZ100 units; with a 1% futures premium, it equals 20.2 units at the same dollar exposure.
