t212-tui 0.4.0

Read-only Trading 212 portfolio terminal

t212

A terminal dashboard for your Trading 212 account. Read-only by design — it can show you everything and touch nothing: the only HTTP verb in the client is GET.

Quick start

uvx t212-tui

That's it — first run opens a guided setup that validates your API key against the live API before saving, or lets you browse sample data with no key at all.

Other ways to run it:

uv tool install t212-tui     # installs the `t212` command
pipx install t212-tui        # same, via pipx
pip install t212-tui         # plain pip

Getting an API key

Trading 212 app → Settings → API (Beta) → generate a key. Enable the read scopes: Account, Portfolio, Pies, Metadata, History. Orders read is optional (it powers the pending-orders panel). Works with Invest and Stocks ISA accounts.

You can also configure outside the TUI:

export TRADING212_API_KEY="<keyId>:<secret>"   # env var, or
t212 config set-key                            # prompt → saved chmod 600

Screens

• Dashboard — value, unrealised/realised P&L, cash breakdown, pending orders, dividend & interest income, net deposits vs. current value, allocation, top movers, equity curve.
• Positions — sortable table with P&L, FX impact and weight; ◔ marks quantity held inside pies; detail view per holding.
• Pies — value, return, dividends and goal progress per AutoInvest pie; drill in for target-vs-actual drift and flagged instrument issues.
• History — orders with realised P&L and fees, dividends with running totals (cash interest included), transactions with running balance; m pages further back.
• Search — the full tradeable universe, filtered as you type, with market hours in the detail view.
• Equity curve — the API has no account-value history, so t212 records a local SQLite snapshot on each poll. The curve grows the longer you use it and is labelled since first run; nothing is back-filled.

Plus: three themes (t), privacy blur for screen-sharing (z), and gains/losses always carry an arrow and sign — never colour alone.

How it behaves

• Talks to Trading 212's /api/v0 endpoints with HTTP Basic keyId:secret auth.
• The API is REST-only, so data is polled — each endpoint on its own cadence within its documented rate limit, with jitter and automatic back-off on 429. Only the active tab's data is fetched.
• Credentials live in ~/.config/t212/config.toml (chmod 600), are sent nowhere except trading212.com, and are never logged or rendered. Snapshots are stored per account in ~/.local/share/t212/.
