# Longbridge Portfolio & Orders

Account data, order management, and portfolio analysis frameworks via Longbridge.

> **Response language**: match the user's input language — English / Simplified Chinese / Traditional Chinese.
> **RULE: Response language priority**: English is the default when language is ambiguous. If the user input is only a slash command, command name, ticker / symbol, or contains no natural-language language signal, you MUST respond in English. Do not infer Chinese from trigger keywords, skill metadata, or examples.

## When to use

Trigger when user asks about: account assets / net value, stock or fund positions, P&L / floating gain/loss, cash flow records, account statements, margin requirements, maximum buy quantity, placing / cancelling / modifying orders, DCA recurring investment status, portfolio diagnosis, rebalancing plan, asset allocation, risk analysis, performance attribution, or tax-loss harvesting.

## CLI Commands

Run `longbridge <cmd> --help` for current flags and output fields.

### `assets` — account net assets, cash, buying power, margin breakdown
### `cash-flow` — cash flow records (deposits, withdrawals, dividends)
### `portfolio` — total assets, P&L, holdings, intraday P&L
### `positions` — current stock positions across all sub-accounts 🔐
### `fund-positions` — current fund positions across all sub-accounts 🔐
### `margin-ratio` — margin ratio requirements for a symbol
### `max-qty` — estimated max buy or sell quantity
### `profit-analysis` — profit and loss analysis
### `statement` — download and export account statements (daily/monthly)
### `bank-cards` — list bank cards for the current account
### `withdrawals` — withdrawal history 🔐
### `deposits` — deposit history 🔐
### `order` — list, detail, buy, sell, cancel, replace orders 🔐 ⚠️ mutating
### `dca` — recurring investment: list, create, update, pause, resume, stop 🔐 ⚠️ mutating

## Auth requirements

- `margin-ratio`, `max-qty`: Public — no login required
- `assets`, `cash-flow`, `portfolio`, `profit-analysis`: 🔐 Requires Quote permission
- `positions`, `fund-positions`, `statement`, `bank-cards`, `withdrawals`, `deposits`: 🔐 Requires Trade permission
- `order`, `dca`, `fund submit-order`, `fund cancel-order` (mutating operations): 🔐 Requires Trade permission — **always present a preview before executing, wait for explicit confirmation**.
  - `order`: dry run by default — the preview prints a confirmation code, and the order is only placed when the identical command is re-run with `--execute <CODE>` after the user confirms. See [references/order.md](references/order.md).
  - `dca`: no dry run — `create` / `update` / `pause` / `resume` / `stop` / `set-reminder` take effect immediately. Show the plan yourself and get explicit confirmation **before** running the command. See [references/dca.md](references/dca.md).
  - `fund submit-order` / `fund cancel-order`: no dry run — without `--yes` the CLI stops at an interactive prompt. Preview first: before `submit-order`, run `longbridge fund validate-order` with the same counter id, `--action`, `--currency`, `--amount` / `--units` and `--dividend-option` (it checks the order and places nothing); for `cancel-order`, show the order with `longbridge fund order <ORDER_ID>`. Show the preview and the exact command you will run, and only after the user explicitly confirms that exact preview, run it with `--yes`. Never run either command without that confirmation, and never pipe input into the interactive prompt.
    - CLI 0.30.0 `fund validate-order` has no `--sell-all`, `--fee` or `--remark`. When the order uses any of them, validate with the comparable arguments (e.g. the held `--units` for `--sell-all`), tell the user which flags the preview could not check, and show the exact `submit-order` command before running it.
- `dca` is available for AP accounts only (not Longbridge US accounts).

## Longbridge US accounts

Longbridge US (LBUS) accounts use separate US account APIs, and some AP-account data does not exist for them:

- **Holdings, cash and buying power**: use `positions`. On a US account its JSON output is an object (`account_type`, `cash_buy_power`, `stock_list`, `option_list`, `crypto_list`, `cash_list`), not the array of `{symbol, name, quantity, ...}` returned for AP accounts. Run `longbridge positions --schema` to check the shape instead of assuming the AP array.
- **Not available for US accounts**: fund positions and margin ratio. Tell the user this data is not available for US accounts instead of retrying.
- **Executions**: CLI 0.30.0 `order executions` is AP-only; for a US account use `order --history --format json` and keep orders whose executed quantity (`executed_qty`) is above 0 (covers partially filled then cancelled/expired orders). It returns one row per order (any status), not one row per fill. On a US account its results are paged (default `--page 1 --limit 20`): raise `--limit` or step `--page` until a page returns fewer than `--limit` orders to cover the whole range. `--start` filters by when the order was placed, so fills of orders placed before the start date (e.g. GTC orders) are missed: widen `--start` back to cover those orders.
- **`portfolio`, `assets`, `cash-flow`, `exchange-rate`**: CLI 0.30.0 does not support these on Longbridge US accounts. Use `positions` for holdings and do not retry these commands; if the Longbridge MCP server is connected, its `account_balance`, `cash_flow`, `exchange_rate` and `stock_positions` tools serve US accounts.

## Frameworks

### Portfolio Diagnosis
Concentration risk, sector distribution, factor exposure, correlation risk. See [references/portfolio-diagnosis.md](references/portfolio-diagnosis.md).

### Portfolio Rebalancing
Weight drift analysis, rebalance trade list, transaction cost and tax impact. See [references/portfolio-rebalance.md](references/portfolio-rebalance.md).

### Asset Allocation
MPT efficient frontier, Black-Litterman, risk parity, all-weather strategy. See [references/asset-allocation.md](references/asset-allocation.md).

### Risk Analysis
VaR (historical/parametric), CVaR, max drawdown, Sharpe/Calmar, historical scenario stress tests. See [references/risk-analysis.md](references/risk-analysis.md).

### Risk-Return Optimization
Risk-adjusted return-optimal portfolios by risk preference and horizon. See [references/risk-return.md](references/risk-return.md).

### Performance Attribution (Brinson)
Allocation/selection/interaction effects, factor alpha/beta, timing ability (T-M model). See [references/performance-attribution.md](references/performance-attribution.md).

### Tax-Loss Harvesting
Identify unrealised losses, suggest substitutes, track 30-day wash-sale window. See [references/tax-harvesting.md](references/tax-harvesting.md).

## Error handling

| Situation | Response |
|---|---|
| `command not found: longbridge` | Install the Longbridge CLI with the bundled installer: `sh ../longbridge/scripts/install-cli.sh` (Windows: `../longbridge/scripts/install-cli.ps1`; paths relative to this skill's directory) after the user confirms — see the `longbridge` skill's *Installing the CLI* section |
| `not logged in` / `unauthorized` | Run `longbridge auth login`; tick Trade permission |
| `order` mutation | Run once to preview; after the user confirms, re-run the same command with `--execute <CODE>` |
| `dca` mutation | No dry run — show the plan and wait for explicit confirmation before running the command at all |
| `only available in the AP data center` / `not available for US accounts` | The data does not exist for Longbridge US accounts; say so, do not retry |
| `fund submit-order` / `fund cancel-order` | Preview first (`fund validate-order` / `fund order <ORDER_ID>`); after the user explicitly confirms that exact preview, run the command with `--yes`. Never run it unconfirmed and never pipe input into the prompt |
| US account + `portfolio` / `assets` / `cash-flow` / `exchange-rate` | CLI 0.30.0 does not support these on Longbridge US accounts; use `positions` for holdings and do not retry (MCP `account_balance` / `cash_flow` / `exchange_rate` / `stock_positions` serve US accounts) |
| US account + `order executions` | CLI 0.30.0 `order executions` is AP-only; use `order --history --format json` and keep orders whose executed quantity (`executed_qty`) is above 0 (covers partially filled then cancelled/expired orders) — one row per order, not per fill. It is paged on US accounts (default `--limit 20`), so use `--page`/`--limit` to fetch them all, and widen `--start` for orders placed earlier (e.g. GTC) |

## MCP fallback

Use MCP server if CLI unavailable. Discover tools at runtime. For Longbridge US accounts, the MCP tools `account_balance`, `cash_flow`, `exchange_rate`, `stock_positions` and `today_executions` / `history_executions` also serve the account data the CLI does not cover. MCP order writes keep the same rule: preview, explicit confirmation, then execute.
