Where you cannot use this

**United Kingdom.** The FCA has banned the sale of crypto derivatives and ETNs to retail consumers since 6 January 2021. UK retail consumers are outside the intended audience for leveraged perpetuals, and using an offshore venue does not restore access to the Financial Ombudsman Service or the FSCS.

**United States.** OKX withdrew from serving US retail customers. Offshore crypto perpetuals are generally unavailable to US retail.

**European Union.** MiCA covers crypto-asset services from December 2024, but derivatives on crypto-assets fall under MiFID II. Whether investor protections such as leverage caps and negative balance protection apply depends on the venue being EU-authorised; most offshore perpetual venues are not.

Check your own regulator's register before depositing anything. A platform's own marketing page is not evidence of your eligibility.

The detail most calculators get wrong: tiers are counted in contracts

This is a genuine structural difference between OKX and both Binance and Bybit.

Binance and Bybit band their maintenance-margin tiers by **position notional in USDT**. OKX bands position tiers by **contract count**, where one contract represents a fixed quantity of the underlying — 0.01 BTC for BTC-USDT-SWAP, for instance.

The consequence is that notional moves with price and a contract count does not:

So applying an OKX ladder as though it were notional-banded selects the wrong tier as soon as price leaves whatever level the ladder was converted at, and the resulting liquidation price is simply wrong. The calculator on this site models both banding conventions separately, which is why this section exists at all.

  • On Binance, if BTC goes from 60,000 to 120,000, the same position doubles in notional and can be pushed into a higher maintenance tier by price alone
  • On OKX, the same position measured in contracts stays in the same tier
  • Compare the tier conventions

OKB changes your level, it does not discount your fee

A second commonly misread mechanic. Binance's BNB applies a discount to the fee at settlement — a multiplier. OKX's OKB holdings instead count toward **the criteria that set your fee level**: holding enough moves you up a level, and a higher level carries lower published rates.

These are two different cost models. A BNB discount can be multiplied in. An OKB holding moves you to a different row of the fee table entirely.

The fee calculator here therefore applies no platform-token multiplier to OKX, because doing so would be wrong. The page says so explicitly.

Fee levels depend on more than volume

OKX levels take account of asset balance and OKB holdings alongside 30-day volume. Two accounts with identical volume can therefore sit at different levels.

This is why any review stating "OKX charges X" holds only under conditions it usually does not state. The calculator uses the published schedule; the level that actually applies to you is the one shown in your account.

Funding settlement

OKX settlement intervals do not always match other venues, and can differ between contracts. Annualising with the wrong interval scales the result by whole multiples — an eight-hour assumption applied to a four-hour contract halves the true figure.

The funding board here infers the interval from historical settlement timestamps rather than assuming eight hours, for exactly this reason.

Five things to verify yourself

  • Whether your jurisdiction is served, and what verification applies
  • How much underlying one contract represents, and the current contract-count tiers
  • The current criteria for your fee level: volume, asset balance and token holdings
  • Supported withdrawal networks, minimums and per-transaction fees
  • Account security: two-factor authentication, withdrawal allowlists, API permissions and IP restrictions

Still pending first-hand testing

No first-hand evidence yet, so no score and no ranking.

  • KYC: documents required, manual review rate, actual completion time
  • Deposits: real arrival time per network with transaction records
  • Order entry: how contract-count sizing feels in the real interface, and what people get wrong about it
  • Volatile markets: fill quality, slippage and order-entry latency
  • Support: question type, channel, first response and resolution time
  • Withdrawals: what triggers security review, fee charged, real arrival time

Risk and limitations

Leveraged trading can lose your entire deposit, and in disorderly markets losses can exceed posted margin. Published rules and regional restrictions both change; the update date reflects when this text was last edited.
