This site is written by people who actually open positions.
Three of us run the editorial desk. One has been trading OKX spot for five years, one has blown up on perps and rebuilt, one writes API code against the exchanges. Every article you read started as one of us opening a real position and walking through the workflow — then writing it down. The numbers are not copied from somewhere else. They come straight from the OKX public market API.
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, annualised funding, grid PnL — six calculators, every formula running in your browser, nothing uploaded.
Position / liq price / maintenance margin
Enter margin and leverage. Get back the liq price and a 1% adverse PnL estimate that lines up with what OKX shows on the position card.
Annualised funding equivalent
8h funding × hold time → annualised rate + cashflow for a spot-vs-perp delta-neutral funding arb.
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.
Each long read came out of one of us opening a position first: the mechanic, then a worked example, then the actual OKX button you click.
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.

Live data, straight from OKX.
Three dashboards, refreshed every 60 seconds against the OKX public endpoint. We display, we do not recommend.
Run the numbers, then place the trade.
Six calculators, all in-browser, nothing transmitted. Type in your parameters, eyeball the formula, then go to OKX.
Position calculator
Given margin, risk budget and stop distance, solves for the maximum contract size.
Open →Funding arb simulator
Spot long + perp short delta-neutral. Splits the funding yield from the funding-rate flip risk.
Open →Grid PnL budget
Type in a band and a density, get an estimate of what is left after fees.
Open →Liquidation price calculator
Isolated and cross margin, with live maintenance margin rate folded in.
Open →Kelly position sizer
Win rate plus payoff plotted against fraction, with the half-Kelly and quarter-Kelly lines marked.
Open →Annualised leverage cost
Funding rate turned into an annual yield. Shows the hidden cost of carrying the position.
Open →How we actually write this stuff.
Not AI-spun. Not lifted from somewhere else. We open the trade, we sometimes lose, then we write it down.
