Sigmavue

Control your SigmaVue trading account from the terminal — and from any MCP-speaking assistant. sigmavue is a thin, read-mostly client over the public SigmaVue API: check status, journal, and portfolio; manage broker accounts and copy-trading groups; and place kill-switch-gated simulated trades — without clicking through the app.

It adds no backend logic and bundles no trading strategies. Every command maps to an API endpoint that already ships. Trade execution is fail-closed and SIM-only.

Install

Run it without installing (requires uv):

uvx --from git+https://github.com/Sigma-Algo/sigmavue-cli sigmavue --help

Install from source:

git clone https://github.com/Sigma-Algo/sigmavue-cli
cd sigmavue-cli
uv sync            # or: pip install -e .
uv run sigmavue --help

pip install sigmavue — coming soon (PyPI publish pending).

Quickstart

# Point at the API (optional). Defaults to the public SigmaVue API.
export SIGMAVUE_API_URL=https://sigmavue-api-green.onrender.com
#   or http://localhost:8000 for a local backend.

sigmavue login --email [email protected]   # password read at a secure prompt
sigmavue status                          # health + account summary
sigmavue accounts list                   # broker accounts your token owns
sigmavue journal list --symbol NQ        # trade journal
sigmavue portfolio                       # open positions + rollup
sigmavue trade execute --symbol NQ --qty 1 --side buy --sim   # SIM-only
sigmavue copy groups list                # copy-trading groups

The bearer token is stored at ~/.sigmavue/auth.json (file mode 0600). Passwords are only ever read from a prompt, never accepted as an argument.

Commands

Command	What it does
login / logout	Authenticate; store or clear the local token
status	Backend health + current user + account summary
accounts list	List broker accounts your token is scoped to (--active)
accounts add	Start a broker OAuth connect (returns an auth_url to open)
accounts remove	Remove a broker account by id
clients list	List managed trading profiles (enterprise)
journal list	List trade-journal entries (--symbol, --type, paging)
portfolio	Current positions + summary (--account, --status)
trade execute	Place an order — kill-switch gated, --sim required
copy groups list	List copy-trading groups
copy groups create	Create a copy-trading group
copy groups add-follower	Coming soon — use the app for now (see below)

Exit codes: 0 success · 1 validation / API / trade-refused · 2 not logged in.

Trading safety

Trade execution is fail-closed and re-checked on every call, before any order request leaves your machine:

1. CLI live-execution is disabled — --sim is required; SIM routes to your active demo broker account.

2. Local kill-switch — the CLI refuses to place an order whenever trading is turned off, via any of:

   • env TRADING_ENABLED set to 0/false/no/off
   • ~/.sigmavue/killswitch.json with {"paused": true} (a missing or corrupt file also blocks — fail-closed)
   • ~/.sigmavue/TRADING_ENABLED file containing 0

   Paths are overridable via SIGMAVUE_KILLSWITCH_PATH and SIGMAVUE_TRADING_ENABLED_PATH.

3. Backend circuit breaker — the order is refused unless the server-side per-user circuit breaker is CLOSED.

Rate limits are respected: a stable User-Agent/X-SigmaVue-Client is sent, and 429 responses trigger bounded Retry-After backoff (--verbose surfaces the rate-limit headers).

MCP server

The same capability layer is exposed as an MCP server, so phone / agent coding assistants get identical reach over one API. It speaks stdio and reads the SAME token sigmavue login stores — there is no credential collection in the MCP surface.

uv sync --extra mcp        # or: pip install "sigmavue[mcp]"
sigmavue login             # once, in a terminal
uv run sigmavue-mcp        # serves over stdio

Add it to an MCP client (use an absolute path so it can start from anywhere):

{
  "mcpServers": {
    "sigmavue": {
      "command": "uv",
      "args": [
        "--directory", "/ABSOLUTE/PATH/TO/sigmavue-cli",
        "run", "sigmavue-mcp"
      ]
    }
  }
}

Claude Code:

claude mcp add sigmavue -- \
  uv --directory /ABSOLUTE/PATH/TO/sigmavue-cli run sigmavue-mcp

It exposes eight tools: sigmavue_status, sigmavue_accounts_list, sigmavue_clients_list, sigmavue_journal_list, sigmavue_portfolio, sigmavue_trade_execute, sigmavue_copy_groups_list, and sigmavue_copy_groups_create. Interactive/destructive flows (login, broker connect/remove) stay CLI-only.

Enterprise

Command breadth is decided server-side by your token: a member sees their own accounts, a manager/enterprise token sees everything it owns — the same accounts list command covers both. A dedicated multi-tenant clients endpoint is on the roadmap; clients list maps to managed trading profiles today.

Adding copy-trade followers (coming soon)

copy groups add-follower is intentionally not enabled from the CLI or MCP yet: there is no atomic add-follower endpoint, and a client-side read-modify-write of the follower list would be unsafe. A server-side POST /api/v2/trading-groups/{id}/followers is planned; until then, add followers in the SigmaVue app. copy groups list and create work fully.

Development

uv sync
uv run pytest -q       # tests use httpx.MockTransport — no live API calls
