How Does MEXC Contract Trading Work? Beginner Step-by-Step Guide

Understanding MEXC Contract Types

1. MEXC offers two primary contract categories: USDT-margined perpetual contracts and coin-margined perpetual contracts.

2. USDT-margined contracts use stablecoin as collateral, with profit and loss calculated in USDT.

3. Coin-margined contracts require the underlying asset as margin — for example, BTC/USD contracts use BTC as margin and settle in BTC.

4. Both types support leverage ranging from 1x to 125x depending on the symbol and user’s tier level.

5. All perpetual contracts on MEXC are index-priced, referencing a composite of major spot exchanges to prevent manipulation.

Account Setup and Margin Management

1. Users must first complete identity verification to access contract trading features.

2. A separate contract account is automatically created upon first deposit into the “Futures” wallet section.

3. Deposits can be made directly via internal transfer from the spot wallet or external blockchain transfers.

4. Margin modes include isolated and cross-margin — isolated assigns fixed margin per position, while cross shares available balance across all open positions.

5. Initial margin, maintenance margin, and liquidation price are dynamically recalculated based on position size, leverage, and mark price.

Data Access and Real-Time Market Feeds

1. Kline data for all perpetual symbols is publicly accessible through REST API endpoints without authentication.

2. The endpoint https://contract.mexc.com/api/v1/contract/kline/{symbol} delivers open, high, low, close, volume, and timestamp fields.

3. Time intervals supported include 1m, 3m, 5m, 15m, 30m, 1h, 2h, 4h, 6h, 12h, 1d, 3d, 1w, and 1M.

4. Historical data retrieval requires UNIX timestamps for start and end parameters, with maximum span limited to 30 days per request.

5. WebSocket streams provide real-time order book depth (depth@10), trade ticks (trade@1s), and funding rate updates every 8 hours.

Order Execution Mechanics

1. Four order types are available: limit, market, stop-market, and take-profit-market.

2. Market orders execute immediately at best available price but may incur slippage during high volatility.

3. Stop-market orders trigger when the mark price reaches the stop price, then execute as market orders.

4. Each order includes configurable parameters such as position side (long/short), reduce-only flag, and post-only restriction.

5. Order rejection occurs if insufficient margin, invalid price deviation beyond 15% of index price, or exceeding position limits set by risk engine.

Funding Rate and Settlement Process

1. Funding occurs every 8 hours at 00:00, 08:00, and 16:00 UTC using a time-weighted average of index and mark prices.

2. The funding rate formula combines interest rate differential and premium index, capped between -0.75% and +0.75% per settlement.

3. Long positions pay short positions when funding rate is positive; the reverse applies when negative.

4. No actual transfer of assets occurs during funding — adjustments are applied directly to wallet equity.

5. Funding payments are visible in the “Funding History” tab and impact unrealized PnL calculations in real time.

Frequently Asked Questions

Q: Can I trade MEXC perpetual contracts using API keys with withdrawal permissions?API keys used for contract trading must have “Enable Trading” permission enabled. Withdrawal permission is not required and should remain disabled for security reasons.

Q: Why does my position show liquidation price even when I’m using cross-margin mode?Liquidation price remains visible because it reflects the theoretical mark price at which total margin falls below maintenance threshold — cross-margin only redistributes available balance but does not eliminate liquidation risk.

Q: How often is the index price updated for BTC/USDT perpetual contracts?The index price updates every second, aggregating weighted mid-prices from Binance, Bybit, OKX, KuCoin, and Coinbase spot markets.

Q: Is there a minimum order size for ETH/USDT perpetual contracts?Yes — the minimum order size is 0.001 ETH, equivalent to approximately $3.50 at current valuation, enforced by the matching engine before order routing.
