Free & open-source · Kotlin Multiplatform
Desktop trading journal that turns broker CSVs into closed positions, charts, and analytics.
eJournal is a free, open-source, local-first desktop trading journal. Import your broker's transaction CSV and it matches every fill into round-trip trades (FIFO), computes realized P&L, and gives you a performance dashboard, a P&L calendar, a sortable trade log, and a per-trade candlestick chart with your entries and exits plotted on it. Your trades and API keys never leave your machine.
Features
Everything you need after the fill.
From raw broker export to a per-trade candlestick chart — matching, math, and charts, all done on your machine.
Automatic FIFO trade matching
Groups individual fills into round-trip trades; handles longs, shorts, scale-ins/outs, and position flips. Closed positions are recomputed from your transactions (never stored), so editing or deleting a transaction just works.
Performance dashboard
Net & gross P&L, win rate, profit factor, expectancy, reward:risk, average win/loss, streaks, average hold time, top/worst trades, and an equity curve — all filterable by date range.
P&L calendar
A month grid color-coded by daily profit/loss; click any day to see the trades you closed.
Per-trade analysis
Candlestick chart (1/5/15-min intraday, or daily/weekly for swing trades) with your entries and exits plotted, a VWAP toggle, a transaction breakdown, and arrow-key navigation between trades.
Sortable, filterable trade log
Every closed position with entry/exit times & prices, shares, P&L, fees, and hold duration.
Drag-and-drop import
Drop a CSV, let eJournal auto-detect the broker, and preview parsed transactions before committing.
Free market data
Yahoo Finance daily bars work out of the box; add free Alpaca keys for 1-minute intraday bars on day trades.
Local-first & private
Everything lives in a single SQLite file under ~/.ejournal; API keys are stored with owner-only permissions on your machine.
Light / dark / system themes
Pick a theme, or let eJournal follow your OS.
Screenshots
See it before you install it.
Four screens, one SQLite file — the dashboard, the calendar, the log, and the per-trade chart.
Integrations
Works with your broker's CSV.
Drop in an export from any of these — or fall back to generic CSV import for anything else.
