Why you ended up here

Probably one of three reasons.

  • You are brand new to perps. Spot already had you confused, and now OKX is throwing "isolated vs cross", "USDT-margined vs coin-margined", "funding countdown", "margin ratio" at you. Every term looks familiar on its own, but you do not know which one to look at first.
  • You have already taken a few losses. You called the direction right but your leverage was too high and you got shaken out. You called it wrong, set the stop too wide, and got liquidated. You do not need "be careful next time" — you need someone to write down the math: at this position size, this leverage, this stop distance, here is the loss you should expect.
  • You are running grids, arbs or funding strategies. The system looked stable, then two weeks in fees and funding ate the entire edge — or one strong directional move sliced your grid in half. You need an estimator you can run before the trade goes live.

All three have one thing in common: the number that hurts you can be worked out in advance. What this site does is move that calculation to before you open the position, instead of leaving you to meet it for the first time in a liquidation notice.

What we cover

Perps, funding, grids, liquidation heatmaps — only on OKX. We do not review spot exchanges, we do not push tokens, we do not run a Telegram signal group. Narrow scope, higher resolution.

In the long reads we try to cover these points:

  1. The exact field you see on the OKX panel, in the panel's own wording.
  2. The formula, the mechanic, the default parameters behind it.
  3. A worked example you can replay on a piece of paper or in a calculator.
  4. Two or three questions you should ask yourself before the next time you place that kind of order.

All the calculators run in the browser. Whatever you type in stays on your tab — the privacy policy explains how to verify that with the network tab.

What we do not do

  • No buy/sell signals. No position screenshots, no candle predictions, no private subscription room.
  • No return promises. Every number you see described as a "sample parameter" is exactly that — a sample. It is not a backtest and it is not a forecast.
  • We do not write about OKX features that do not exist. Every button, field and parameter we mention maps to a real position on the OKX trading panel.
  • No skipping disclosure. Every CTA on the site is a direct link to OKX's official site, tagged rel="sponsored nofollow". The referral disclosure lives in the footer and on its own page.

About the desk

Bylines on this site read "KX Perp Kit Editorial Desk" — a collective pen name. We do not link to personal Twitter, GitHub or LinkedIn. A content site has no need to drag the writers' offline identities into it. The two places you can hold us accountable are these.

  • Corrections and revisions — historical errors, dated, with original text and the fix.
  • Email [email protected] — if you find something wrong, the reply will include a signed acknowledgement and the credit goes on the corrections page (pen name accepted).

Our relationship with OKX

Every CTA on this site goes straight to OKX's official site (okx.com) for sign-up or login, with our referral code sitting in the link. Taking that route does not change the fees you pay, but it tells OKX's Affiliate system that you found them through us. The details are on the Affiliate Disclosure.

That is the entire extent of the relationship. We are not on an exclusive contract. We do not take editorial payment from OKX. We are not OKX's PR shop. Where OKX's interface is unclear or its docs mislead, we say so.

How to use this site

Risk notice: Perpetual futures are high-risk leveraged derivatives — you can lose your entire margin and then some. Everything on this site is educational. None of it is investment advice. Size your trades against losses you can afford before you click.
