OKX perpetual toolkit — seven tools.
Six perpetual calculators — position size, liq price, funding cash flow, grid profit, Kelly sizing, annualized funding — plus a tick-off account & KYC setup checklist. All math runs in your browser — inputs never leave the tab. Where OKX exposes a public API (funding rate, mark price), the form auto-fills.
Perp Position Calculator
Enter margin, leverage and entry price for notional, base-asset quantity and PnL after a 1% adverse move. Isolated liquidation uses a simplified estimate; cross needs account data.
Open tool →Perpetual Funding Cash-Flow Estimator
Estimate the perpetual leg as notional × assumed funding rate × assumed settlement count, with position direction. It excludes the spot leg, fees and return on total capital.
Open tool →Grid Profit Estimator
Enter price band, grid count and daily vol — estimate expected daily triggers, per-grid yield, net PnL after fees and capital usage. A math baseline for your grid bot.
Open tool →Kelly Position Calculator
Enter win rate and payoff; get full Kelly, half Kelly and quarter Kelly position sizes side by side. Crypto perps generally call for quarter Kelly — this tool shows all three tiers.
Open tool →Annualized Funding Calculator
Under a constant assumed rate and specified interval, compare notional and initial-margin annualized measures, then estimate cash flow for an explicit settlement count. Not compound yield or loan APR.
Open tool →Liquidation Price Calculator
Compare long and short isolated liquidation prices using entry price, leverage and maintenance margin rate. The linear USDT model omits fees, funding and added margin.
