longbridge-profit-analysis

Full account P&L analysis — simple return, time-weighted return (TWR), per-symbol attribution, and market-level breakdown — sourced from the user's Longbridge account.

Response language: match the user's input language — Simplified Chinese / Traditional Chinese / English.

When to use

• "我账户今年赚了多少", "我今年的收益率", "account P&L this year"
• "我的时间加权收益率", "TWR", "time-weighted return"
• "TSLA 这只股票我亏了多少", "holding P&L for NVDA"
• "美股账户盈亏", "profit by market", "HK market P&L"
• "帮我分析一下 Q1 业绩", "Q1 performance analysis"
• Prefer over longbridge-portfolio when the user wants return-rate metrics (TWR eliminates cash-flow distortion) or detailed per-symbol attribution.

Workflow

1. Confirm login; if not logged in, tell user to run longbridge auth login with Trade scope.
2. Identify the operation: overall P&L / per-symbol detail / by-market / custom date range.
3. Extract date range from context if specified; default to YTD if not stated.
4. Call CLI with --format json; run --help if unsure about flags.
5. Present: overall return %, absolute gain/loss, TWR (note: eliminates cash-flow timing distortion), top contributors, and breakdown table.

CLI

Run longbridge profit-analysis --help to verify exact flags before use.

# Overall account P&L with TWR (default: YTD or account lifetime)

# Custom date range
longbridge profit-analysis --start 2026-01-01 --end 2026-04-30 --format json

# Per-symbol P&L detail
longbridge profit-analysis detail TSLA.US --format json

# P&L broken down by market
longbridge profit-analysis by-market --market HK --format json

# Check available flags and subcommands
longbridge profit-analysis --help

Output

Overall P&L

| Field | 简体 | 繁體 | English | |---|---|---|---| | simple_return | 简单收益率 | 簡單收益率 | Simple return | | twr | 时间加权收益率 | 時間加權收益率 | Time-weighted return (TWR) | | total_profit | 总盈亏 | 總盈虧 | Total P&L | | realized | 已实现盈亏 | 已實現盈虧 | Realized P&L | | unrealized | 未实现盈亏 | 未實現盈虧 | Unrealized P&L | | period | 统计期间 | 統計期間 | Period |

TWR note: Always explain TWR briefly — "时间加权收益率消除了追加/取出资金对收益率的影响，是更客观的业绩衡量指标。" / "時間加權收益率消除了追加/取出資金對收益率的影響，是更客觀的業績衡量指標。" / "TWR removes the effect of cash flows (deposits/withdrawals), providing a purer performance measure."

Per-symbol detail

Render: symbol, market, cost basis, current value, unrealized P&L, realized P&L, total return %.

By-market

Render: market (US / HK / CN / SG), total value, P&L, return %.

MCP fallback

If longbridge CLI is not installed, use:

When the CLI is unavailable, fall back to the MCP server. Discover available tools from the MCP server's tool list at runtime — do not rely on hardcoded tool names.
