    faqDecisionFrequency: 'How often does the AI make decisions?',
    faqDecisionFrequencyAnswer:
      'Configurable! Default is every 3-5 minutes. Too frequent = overtrading, too slow = missed opportunities.',

    faqCustomStrategy: 'Can I customize the trading strategy?',
    faqCustomStrategyAnswer:
      'Yes! You can adjust leverage settings, modify coin selection pool, change decision intervals, and customize system prompts (advanced).',

    faqBinanceApiFailed: 'Binance API call failed (code=-2015)',
    faqBinanceApiFailedAnswer:
      'Error: "Invalid API-key, IP, or permissions for action". Solutions: Add server IP to Binance API whitelist; Check API permissions (needs Read + Futures Trading); Ensure using futures API not unified account API; VPN IP might be unstable.',

    faqBinancePositionMode: 'Binance Position Mode Error (code=-4061)',
    faqBinancePositionModeAnswer:
      'Error: "Order\'s position side does not match user\'s setting". Solution: Switch to Hedge Mode (双向持仓) in Binance Futures settings. You must close all positions first before switching.',

    faqNoTrades: '为什么我的交易员不开仓？',
    faqNoTradesAnswer:
      '常见原因：AI 根据市场情况决定"等待"；余额或保证金不足；达到持仓上限（默认最多 3 个仓位）；查看故障排查指南了解详细诊断。',

    faqDecisionFrequency: 'AI 多久做一次决策？',
    faqDecisionFrequencyAnswer:
      '可配置！默认是每 3-5 分钟。太频繁 = 过度交易，太慢 = 错过机会。',

    faqCustomStrategyAnswer:
      '可以！您可以调整杠杆设置、修改币种选择池、更改决策间隔、自定义系统提示词（高级）。',

    faqMaxPositions: '最多可以同时持有多少个仓位？',
    faqMaxPositionsAnswer:
      '默认：3 个仓位。这是 AI 提示词中的软限制，不是硬编码。',

    faqMarginInsufficient: '保证金不足错误 (code=-2019)',
    faqMarginInsufficientAnswer:
      '常见原因：资金未划转到合约账户；杠杆倍数设置过高（默认 20-50 倍）；已有持仓占用保证金；需要先从现货账户划转 USDT 到合约账户。',

    faqHighFees: '交易手续费太高',
    faqHighFeesAnswer:
      'NOFX 默认 3 分钟扫描间隔会导致频繁交易。解决方案：将决策间隔增加到 5-10 分钟；优化系统提示词减少过度交易；调整杠杆降低仓位大小。',

    faqNoTakeProfit: 'AI 不平掉盈利的仓位',
    faqNoTakeProfitAnswer:
      'AI 可能认为趋势会继续。系统目前缺少移动止盈功能。您可以手动平仓或调整系统提示词使其在获利时更保守。',

    // Technical Issues
    faqBinanceApiFailed: '币安 API 调用失败 (code=-2015)',
    faqBinanceApiFailedAnswer:
      '错误："Invalid API-key, IP, or permissions for action"。解决方案：将服务器 IP 添加到币安 API 白名单；检查 API 权限（需要读取 + 合约交易）；确保使用合约 API 而非统一账户 API；VPN IP 可能不稳定。',

    faqBinancePositionMode: '币安持仓模式错误 (code=-4061)',
    faqBinancePositionModeAnswer:
      '错误信息："Order\'s position side does not match user\'s setting"。解决方法：切换为双向持仓模式。登录币安合约 → 点击右上角偏好设置 → 选择持仓模式 → 双向持仓。注意：先平掉所有持仓。',

    faqPortInUse: '后端无法启动 / 端口被占用',
    faqPortInUseAnswer:
      '使用 "lsof -i :8080" 查看占用端口的进程，在 .env 中修改端口：NOFX_BACKEND_PORT=8081。',

    faqFrontendLoading: '前端一直显示"加载中..."',
    faqFrontendLoadingAnswer:
      '使用 "curl http://localhost:8080/api/health" 检查后端是否运行。应该返回 {"status":"ok"}。如果不是，查看故障排查指南。',

    faqDatabaseLocked: '数据库锁定错误',
    faqDatabaseLockedAnswer:
      '使用 "docker compose down" 或 "pkill nofx" 停止所有 NOFX 进程，然后使用 "docker compose up -d" 重启。',
