News & research
News
A self-hosted news aggregator. Build dashboards (e.g. Crypto, Macro), add sources to each, and let the scheduler poll them in the background.
Sources
- RSS / Atom: paste a feed URL, done.
- API (JSON) for anything without RSS: set the endpoint, method, headers and query params, then map JSON paths to item fields (items array, title, URL, date, summary, unique id for dedup). API keys go into per-feed secrets, stored encrypted and referenced as
{{secret:NAME}}in headers or params, and are never shown again.
A feed URL, header or param can also carry a {{vault.item}} placeholder pointing at the shared Vault. The scheduler resolves it at poll time, so a key is reused across feeds and modules without ever being stored in the feed config.
Each source has its own poll interval; duplicate sources are detected so the same feed isn't fetched twice across dashboards. Start/stop polling per dashboard, or refresh a source on demand.
Reading
Filter items by search, source, type and date range; compact or full view; optional 60-second auto-refresh with a "{n} updates, click to load" banner. A news widget can also sit on your dashboard home page.
Mailbox
Your newsletters, market-news mail and broker mail, read from your own mailbox: nothing transits a third party.
Connecting a mailbox
Pick your provider (Fastmail, Gmail, iCloud, Zoho, mailbox.org, Posteo, Migadu, Proton Bridge or any other IMAP server) and the server settings come pre-filled; you supply an app password, which is stored in the shared Vault and nowhere else.
Outlook.com / Microsoft 365 no longer accept a password for IMAP, so they sign in with OAuth instead: a tab opens at Microsoft, you approve the access, and it comes straight back to this app (authorisation code + PKCE, no secret is stored anywhere). It needs a one-off, free app registration of your own: Entra ID → App registrations → new registration, then Authentication → Mobile and desktop applications with the redirect URI the form shows you (http://localhost:5454/mailbox/oauth on a default local install), public client flows allowed, and API permissions → delegated IMAP.AccessAsUser.All. Paste the Application (client) ID into the form. The resulting sign-in is encrypted in the vault and renewed automatically at every fetch.
Microsoft only accepts a redirect URI that is https://…, or http:// on localhost, and its portal refuses an http URI typed as 127.0.0.1, so open the app at http://localhost:5454 (the port is ignored when matching a localhost redirect) or put it behind HTTPS in Settings → Network. If yours is a plain-HTTP LAN address, the sign-in falls back to a code you type on microsoft.com/devicelogin; that still works for personal Outlook.com accounts, but Microsoft 365 tenants now block device-code sign-in by default.
That renewal is the only thing to know about maintenance: Microsoft drops a sign-in after 90 days without use, so a mailbox you paused for months will ask to be reconnected. The app warns after 60 idle days and, if the sign-in is revoked (password change, MFA reset, admin policy), the mailbox shows Sign-in needed with a Reconnect button instead of failing silently.
Access is strictly read-only: the folder is opened read-only, and nothing is ever flagged, moved or deleted on your server. Connect several mailboxes if you keep more than one.
Consider a dedicated address for newsletters. Your personal mail then stays out of the app entirely, the app password is revocable in one click, and the day a sender leaks its list you know exactly which one did.
What gets kept
Mailing-list mail (anything carrying List-Unsubscribe, List-Id or Precedence: bulk) is kept automatically. Everything else is only recorded as a sender awaiting your decision, and no content is stored until you file it. That is how a broker's statements get in: one click on the new sender, filed as Broker.
Senders are filed in four categories (News, Newsletter, Broker, Other), switchable at any time, and the reading screen has a one-click toggle per category plus a filter by mailbox when you have several.
Reading
Messages are sanitised on arrival (scripts, styles, forms and frames removed) and displayed in a sandboxed frame. Remote images stay blocked until you ask for them, so the tracking pixel in a newsletter never fires and the sender cannot tell you opened it. Attachments (broker statements, PDFs) are downloadable from the message.
Per message: star, mark unread, archive, Remind me (tonight / tomorrow / this weekend, straight into RemindMe) and Unsubscribe, sent for you when the sender supports one-click, opened in a tab otherwise.
The store
The Store tab is your own list of newsletters: one card per publication with a name, a link, a short description and a topic (mindset, finance, trading, geopolitics, economics, other), grouped by domain and openable in one click. It stands alone, useful even with no mailbox connected.
Economic Calendar
Upcoming macro events (central-bank decisions, CPI prints, employment data) in a calendar view, so you know what's ahead of your session. One click adds a reminder for an event.
FinanceDatabase
A searchable catalog of 300,000+ instruments: equities, ETFs, funds, indices, currencies and cryptocurrencies.
On first use you install the catalog (a one-time ~15 MB download, imported in the background). After that it lives locally and searches never touch the network. Search by symbol or name, filter by asset type and attributes, and star instruments into favorites, organized in folders with notes (e.g. a Watchlist folder).
The catalog has its own release cycle, separate from the app: the header shows which snapshot is installed and a Check for updates button asks the publisher whether a newer one exists. Updating re-imports the catalog in place; your favorites survive and re-link to the new rows.
The catalog is built from the open-source FinanceDatabase project by Jeroen Bouma, a community-maintained dataset of financial instruments.
Resources
A bookmark library for trading books, articles, videos and tools: name, optional link, description, organized in categories. Simple on purpose.
Three displays: cards, list, and a gallery with a thumbnail per bookmark. A thumbnail is uploaded, pasted as a URL, or fetched from the link's own social preview in one click; a bookmark without one gets an initials tile instead of a hole in the grid.
Community Docs
Guides written by the community, synced from the library on opentraderworld.com and readable offline inside the app. Browse by category, search, and star favorites.
Docs show as cards or as a list, your choice, and a category card previews the docs it holds so you know what is inside before opening it.
You can contribute: write a document in the Editor and use Submit for publication. It goes to a review queue and appears in everyone's library once approved.
