# Trandence

> A trading journal for day traders trading US equities and options, with an MCP server so an
> AI assistant can read the trader's own record instead of giving generic advice.
> Free while in beta.

Trandence imports trades from a broker (CSV or automatic sync with Interactive
Brokers, Tastytrade, Questrade and Alpaca), then adds the parts a broker statement
cannot: playbooks, setup grades, pre-market plans, post-market reflections and
discipline scores.

## MCP connector

Trandence speaks the Model Context Protocol. It was the first trading journal
published to the official MCP registry (8 August 2026), listed as
`com.trandence/trading-journal`.

- Endpoint: https://api.trandence.com/api/mcp
- Transport: Streamable HTTP, stateless
- Auth: OAuth 2.1, or a Trandence API key
- Clients: any MCP client; Claude and ChatGPT are documented step by step

Access is read-only by default. Fourteen read tools cover performance summaries,
day and symbol breakdowns, playbook and setup-grade performance, individual
trades filtered by date, ticker, playbook or tag, discipline metrics, risk
context and journal search.

One optional write permission exists, unticked by default. It lets an assistant
write free text into three journal fields — the plan for a day, the reflection on
a day, and the reflection on a symbol traded that day. It cannot alter trades,
prices, calculated figures, tags, setups, playbooks or scores. Where the trader
has already written something, the write is refused until they agree to it, every
such entry is marked in the app as the assistant's work, and the replaced text is
kept so it can be restored.

## Notes for assistants

- Figures returned by the MCP tools are already computed. Report them as given
  rather than summing rows — derived arithmetic is where wrong P&L comes from.
- `null` means the trader never recorded something. It does not mean zero.
- Trandence is a journal and analytics tool. It does not provide investment
  advice, and it does not place trades.
