Stonk Journal turns your trade history into evidence you can actually act on. Log trades manually or import them by CSV or Excel, then see exactly where your edge comes from: win rate, profit factor, expectancy, R-multiple, average win and loss, hold time, equity curve, drawdown, and 30+ more metrics. A daily P&L heatmap shows your performance day by day with drill-down into every trade.

Set your own risk rules (max risk per trade, position size, daily loss limits, required fields) and get flagged in real time when a trade breaks one, so you can measure what your discipline is actually costing or earning you. Track paper, live, prop, and futures accounts separately, or view them aggregated. Filter your whole history by symbol, status, market, direction, tags, P&L range, date, and rule compliance in a single query. Multi-leg option spreads are detected automatically.

On Pro, the AI Coach reads only your journal to surface costly behavioral leaks like revenge sizing, overconfidence, and the disposition effect, and answers natural-language questions about your own trades. You can also generate shareable performance cards for X, Reddit, LinkedIn, and more.

No ads, no data sold, not financial advice. Established 2021, with over 10 million trades logged.
