Blotter — P&L Calendar

Unofficial P&L calendar for Trade Republic traders: daily realized profit/loss, per-trade detail, tax breakdown. All local.

Blotter turns your Trade Republic order history into a clear performance dashboard — entirely on your own computer. • Calendar of daily realized profit & loss, colored green/red • Per-execution detail: contracts, price, value, and realized P&L • All-time and monthly gross → fees → tax → net breakdowns • Yearly view with German capital-gains tax (Kapitalertragsteuer + Solidaritätszuschlag, optional church tax), loss carry-forward and your annual allowance • Best/worst day, green-day rate • Light / dark theme and an optional side-panel view How it works: while you're logged in to Trade Republic, Blotter reads your own executed orders from Trade Republic's web API (read-only) and computes realized P&L using average-cost basis per instrument. Everything is stored locally in your browser and is never uploaded — there is no server, no analytics, no tracking. Unofficial and independent. Not affiliated with, endorsed by, or connected to Trade Republic Bank GmbH. Trade Republic is a trademark of its respective owner. Requires Trade Republic's new web trading interface (the desktop layout with an Orders page). It does not work with the older web app. Note: Trade Republic has no public API; Blotter reads the same private endpoints your browser already uses. A Trade Republic frontend change may temporarily break data capture until the extension is updated.
