EDITOR'S NOTE

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.

TOOLS

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.

LONG READS

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.

EDITORIAL

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.

Hands-on, real position

Every article starts with one of us putting 100 to 1,000 USDT on the line and walking through the actual OKX workflow.

Data from the OKX public API

Every dashboard, tool and ticker calls the OKX public REST endpoints. No caching, no second-hand data, no editorial spin.

External sources, properly cited

Every cornerstone read links to at least three outside references — CoinGlass, OKX Academy, Investopedia, CoinDesk Learn.

Errors fixed in public

You spot something wrong, you email us, we fix it the same week, your handle goes on the corrections page.

FAQ

The questions we get asked most.

What is the relationship between this site and OKX?
We are an independent third-party site. We are an OKX Affiliate Partner (referral code OK6512) and we earn a service fee on accounts you open through the referral link. We are not an OKX-owned page. We never collect your password and we never withdraw your funds. Every "go to OKX" link points at the real okx.com.
What do I get from signing up with OK6512?
When you register through this code, OKX applies a fee discount under its Affiliate programme*. The exact percentage shifts with OKX policy, so we do not promise a number up front. Your trading cost does not go up because of the code — the discount is funded by OKX out of the fees it collects, and our service fee is a separate flow.
How accurate is the data?
The dashboards call the OKX public REST API directly (/api/v5/public/funding-rate, /api/v5/market/tickers and so on). Nothing is cached. The calculators are pure math; the formulas are printed at the bottom of each tool page. Your inputs stay in the browser tab — we have no server-side logging for them.
Is OKX available where I live?
OKX makes the final call on your IP at sign-up. Commonly restricted or unavailable jurisdictions include the United States, Quebec (Canada), the United Kingdom (retail derivatives), Iran, North Korea and others. We do not promise availability anywhere. Open the OKX sign-up page and let it confirm.
How should I actually start after reading all this?
Suggested order: 1) Read the stop-loss / position size paradox to clear the most expensive mistake. 2) Walk through the OKX 24h workflow. 3) Open the position calculator and plug in your trade. 4) Try 100 to 200 USDT on OKX as a sizing experiment. 5) Once you have 30 days of records, use the Kelly sizer to set your real position fraction.
Does the referral code make my fees higher?
No. The Affiliate service fee comes out of the fees OKX already collects — it is not added on top. If you register with OK6512, your trading cost is less than or equal to opening a plain OKX account, because of the included fee discount.
