MEXC futures trading bot

TypeScript Node CLI for rule-based automation on MEXC USDT-margined perpetual contracts (contract.mexc.com). Ships with moving-average crossover and grid strategies, dry-run mode, and notional risk caps.

Requirements

• Node.js 20+
• MEXC futures account with either Open API credentials (MEXC_API_KEY + MEXC_API_SECRET) or a web session key/cookie pair
• Sufficient USDT margin for the configured symbol and leverage

Setup

cp .env.sample .env
npm install

Commands

Command	Description
npm run bot	Long-running strategy loop (BOT_DRY_RUN=true recommended first).
npm run build	Emit dist/.
npm run typecheck	tsc --noEmit.

Strategies

• ma-cross (default): 9/21 SMA crossover filtered by RSI; closes on opposite cross.
• grid: Places conceptual buy bands below spot and takes profit toward upper grid levels.

Set BOT_STRATEGY=grid or ma-cross in .env.

Safety

Always start with BOT_DRY_RUN=true. Perpetual futures carry liquidation risk—RISK_MAX_POSITION_USDT and RISK_RISK_PERCENT cap sizing but do not guarantee profitability.
