XXKK perpetual contract specs explained, contract size, tick size, min order, max leverage, and where to find each number

Placing a perpetual order without checking the contract’s specs is like driving with the speedometer covered. You can still move, but you won’t know what your inputs really mean, or why the order ticket rejects a size that “looks fine.” This guide breaks down XXKK perpetual contract specs in plain terms, shows the simple formulas that connect the numbers to position sizing and PnL, and explains where to verify each value inside the trading interface. It also calls out common traps like rounding, tiered leverage limits, and spec changes after symbol updates. XXKK is built around a user-first approach, strong security controls, and clear risk handling. Use that structure to your advantage by verifying every spec before you scale size. The contract specs that control position size, pricing, and risk Most traders care about six numbers because they decide what you can type into the order ticket, what fills, and what liquidation risk looks like. 1) Contract size (and what “1 contract” equals)Contract size defines how much underlying exposure you get per contract. On linear (USDT-margined) perps, it’s often expressed as a quantity of the base asset (or a notional convention). Your position notional is driven by this value. Core formula (generic): Notional (quote) = Contracts × Contract Size × Price Why it matters: Fees, margin requirements, and liquidation tiers are usually based on notional, not “number of contracts.” Where to find it on XXKK: Open the perpetual trading page for the symbol, then look for an Info, Details, or Contract panel near the order book or chart. Many interfaces also show it inside an instrument pop-up when you click the pair name. 2) Tick size (minimum price movement)Tick size is the smallest allowed price step. If tick size is 0.10, you can’t place a limit at 42000.05. The UI will round or reject it. PnL intuition: Your PnL changes continuously with price, but your limit orders can only rest at tick increments, which affects fills and slippage control. Precision rule: Allowed price = integer × tick size Where to find it on XXKK: Check the order ticket’s price field behavior (try typing extra decimals), then confirm in the same contract details panel. If XXKK exposes rule text near the price box, it often states “price precision” or “tick size.” 3) Step size (lot size) and minimum orderStep size (also called lot size) is the smallest change in order quantity. Minimum order is the smallest allowed quantity. These are related, but not identical. Quantity rule: Allowed size = minimum order + (integer × step size) Common outcome: A size might be above the minimum but still invalid because it doesn’t match the step size increments. Where to find it on XXKK: Look in the order ticket under the quantity box for hints like “Min” or “Step.” If it’s not shown, the contract details panel usually lists “quantity precision,” “lot size,” or “min size.” 4) Quote currency vs margin currency (what you trade in, what you post as collateral)For many linear perps, PnL is quoted in USDT and margin is also USDT, but exchanges can support multi-collateral setups or coin-margined contracts. Why it matters: It changes how you think about collateral risk (stablecoin collateral vs coin collateral) and how funding, fees, and PnL settle. Where to find it on XXKK: In the contract details panel, look for Settlement, Margin, or Quote fields. On some layouts, the pair label itself hints at it (example: “BTCUSDT Perp” suggests USDT quote). 5) Maximum leverage (and why it may not be a single number)The headline max leverage is not always what your position gets. Many venues apply tiered leverage based on position size, and cross vs isolated margin can change your usable leverage. Quick relationship: Initial margin rate ≈ 1 / leverage (before fees and buffers) Reality check: Maintenance margin rate rises with larger notional, so liquidation can come sooner than simple math suggests. Where to find it on XXKK: Check the leverage selector on the order ticket, then open any Risk Limit, Margin Tier, or Position Tier view linked from the same screen. If your leverage slider tops out lower after you increase size, that’s tiering in action. 6) Funding interval (when funding is exchanged)Perpetuals use funding to keep the contract price near spot. Funding timing and countdown matter if you hold positions through multiple intervals. Where to find it on XXKK: On the perp trading screen, look for a funding widget showing the current funding rate and a countdown to the next timestamp. If a separate details view exists, it may also show the interval length. For background on how exchanges document funding and contract specs, see OKX’s perpetual futures guide. Where to find XXKK perpetual contract specs (UI checklist and verification steps) Public web search results in January 2026 don’t reliably surface a single, official XXKK page that lists every perp’s contract size, tick size, lot size, min order, leverage tiers, and maintenance margin schedule in one place. That means the source of truth is typically inside the trading UI, and sometimes inside API docs if you’re integrating. Use this routine to locate each number quickly: Step 1: Open the instrument’s details panelOn the perp trading screen, click the symbol name (top-left area on many layouts) or an Info/Details icon. Your goal is to find a panel that lists fields like contract size, tick size, quantity precision, and settlement. For an example of how exchanges present formal “contract specifications” pages, compare the structure used by Power Trade’s contract specifications guide. The labels vary by venue, but the same core fields appear. Step 2: Validate tick size and step size by testing the order ticketEven if you see a number in the panel, confirm it behaviorally: Type a limit price with extra decimals, then see whether the UI rounds or rejects. That confirms tick size behavior. Type an order quantity that is “almost valid” (example: add one extra decimal), then adjust until it’s accepted. That reveals step size and min order constraints. Step 3: Confirm max leverage using the leverage selector and tier viewSet isolated margin, then open the leverage selector. Increase your intended order size and watch the maximum allowed leverage. If it drops, you’ve hit a higher risk tier. To understand how other venues publish leverage by tier and margin class, see Kraken’s linear perpetual contract specifications. Use it as a terminology reference, not as XXKK’s numbers. Step 4: Check funding timing and price references used for liquidationFunding is usually shown with a countdown. Liquidation risk depends on which price reference is used (last price, index, mark). Keep a reference open on how these prices differ because it affects stops and liquidation expectations.

Step 5: Tie specs to costs before you scaleContract size affects notional, and notional drives fees and funding impact.

Summary table: what to record for each XXKK perp (and where to verify it) Record these fields per symbol. If a value can’t be confirmed from a visible UI label, verify by testing order entry (price and size) and checking the position or risk views. Spec to record What it controls Where to verify on XXKK Contract size Notional calculation and exposure per contract Contract details panel for the symbol Quote currency What your PnL is measured in Symbol details, settlement info Margin currency What collateral you post Margin/settlement fields, margin mode screen Tick size Allowed limit price increments Contract details panel, price field rounding test Step size (lot size) Allowed size increments Contract details panel, size field acceptance test Minimum order Smallest allowed order size Order ticket min hints, size validation Max leverage Highest available leverage, often tiered Leverage selector, risk limit or tier view Funding interval (if shown) When funding is paid/received Funding widget with countdown on trading screen Maintenance margin reference Liquidation buffer and tier rules Risk limit/margin tier view, position details For protocol-level context on how perpetual specs are defined (contract unit, funding, margin concepts), see Perp Protocol’s perpetual swap spec. Common gotchas that cause rejected orders or surprise risk Rounding can change your intended order. If you type a price or size that doesn’t match tick size or step size, the UI may round. Rounding up can increase notional, and that can push you into a tighter leverage tier. Market orders can behave like “min notional” filters. Even when the minimum quantity is met, a market order can fail if it would execute too small after rounding, or if the engine enforces additional protections during low liquidity. If your market order fails, retry with a slightly larger size, then switch to a limit order to control execution. Max leverage is often capped by position size. Don’t plan a trade based on the highest slider number alone. Set your target size first, then check the maximum allowed leverage for that size. Symbol migrations can reset expectations. After contract upgrades (symbol renames, multiplier changes, new margin currency), old screenshots and saved templates can become wrong. Re-check contract size, tick size, and min order whenever a symbol looks “new.” Liquidation depends on reference price logic. If liquidation triggers on mark price, watching only last price can mislead you. Keep mark price visible if the UI allows it, and review how index and mark behave during spikes. Conclusion Perpetual trading gets calmer when you treat specs as part of risk control, not fine print. Record contract size, tick size, step size, min order, max leverage tiers, and funding timing before you place size. When a number isn’t clear, verify it by testing the order ticket and checking the risk views. That habit, plus accurate specs, keeps execution clean and helps you avoid preventable liquidations.
