Open your first OKX perpetual with a fee rebate.

Every number here is one you can work out yourself.
Before opening an OKX perpetual position, what will the fees cost, and how far away is liquidation? The articles show the assumptions and arithmetic; the calculators let you try your own numbers. The market ticker reads OKX public data. The floating cards above and chart previews are labelled examples, not updating market quotes.
We do not sell courses. We do not run signal groups. We do not place trades for you. What we do is translate the jargon — funding rate, liquidation, grid, Kelly — into the call you have to make at the order panel. And we show you what the OKX API actually returns. After that the decision is yours.

Cost the trade before you place it.
Position size, distance to liq, annualized funding, grid PnL — six calculators, every formula running in your browser, nothing uploaded.
Position / liq price / maintenance margin
Enter margin, leverage, entry price and maintenance margin rate to estimate a simplified isolated liquidation price and PnL after a 1% adverse move.
Funding cash flow and annualization
Under a constant assumed rate, compare notional and initial-margin annualized measures, then estimate cash flow for an explicit settlement cadence and count. This is not compound yield or loan APR.
Grid PnL budget
Price band + grid density + realised vol → expected daily PnL plus the loss if the band breaks one-sided.
From not knowing to placing the trade.
These long reads work through how each mechanic is calculated, most with a set of numbers you can redo yourself, and point to where it lives on the OKX screen.
OKX perp fees and funding rate, fully unpacked
Where maker rebates and taker fees actually show up, how often funding settles, who pays whom when the rate flips negative. Read this table first.
Read full →Leverage vs liq price, the math
5x and 50x look similar on a candle chart. In the margin formula they are an order of magnitude apart. Run the numbers by hand once.
Read full →Grid strategy handbook
Arithmetic vs geometric, how many grids, what to do when a one-sided move slices straight through. Write the assumption down before you launch.
Read full →The stop-loss / position size paradox
Tight stop, big position — sounds clever. Tight stop also means lower hit rate. We rewrite this using win rate times payoff.
Read full →Reading the liquidation heatmap
That dark band is not a support level — it is everyone else's liq price. Learn to tell "what I think" from "where the market is forced to print".

Sign-up, sub-account, transfer, first order — every button mapped to its screenshot. The full picture for a first-timer.

Data pulled straight from OKX.
Open a dashboard for funding rates, open interest or long/short ratios. Each page attempts a refresh every 60 seconds using OKX public data; long/short requests pass through this site. The pictures below are examples. Check the dashboard itself for readings and update status.
Run the numbers, then place the trade.
Six calculators plus a sign-up checklist, all in-browser, nothing transmitted. Type in your parameters, eyeball the formula, then go to OKX.
Position calculator
Enter margin, leverage and entry price for notional, base-asset quantity and PnL after a 1% adverse move. Isolated liquidation is a simplified estimate; cross needs account data.
Open →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 →Grid PnL budget
Type in a band and a density, get an estimate of what is left after fees.
Open →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.
Open →Kelly position sizer
Win rate plus payoff plotted against fraction, with the half-Kelly and quarter-Kelly lines marked.
Open →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 →OKX account checklist
Everything to line up before sign-up, KYC and your first deposit — tick it off step by step.
Open →How we actually write this stuff.
The formula is on the page, the numbers are yours to check, and when we get something wrong we fix it in public.
Written against the OKX page
Every field and every button we mention lines up with where it actually sits on the OKX trading page. We don't write about features the platform doesn't have.
Data from the OKX public API
The ticker and dashboards use OKX public data, with long/short requests forwarded by this site. Calculators work in your browser from the values you enter; they do not read your exchange account.
Sources you can click through
Where a piece states a rule or a mechanic, it links to the original — the OKX help center, CoinGlass data pages and the like — so you can check it yourself.
Errors fixed in public
You spot something wrong, you email us, we fix it the same week, your handle goes on the corrections page.
