Every fill set down in ink, every edge measured. TailJournal turns your trades into one clear, honest read — automatic broker sync, AI pattern detection, and the analytics serious traders use to compound their edge.
Native iPhone & Android apps are on the way — your full TailJournal dashboard, trades, journal, reports, replay, backtesting and AI coach, synced with the web app in real time. Store links go live at launch.

Replay any fill against the move that actually happened — entries, exits, levels and your notes, scrubbed at your own speed. The closest thing to a film room a trader has.
TailJournal reads your own record and writes it back in plain English — the revenge trades, the oversizing, the sessions that pay and the habits that quietly bleed you.
Expectancy, Sharpe, drawdown, win rate by hour, P&L by tag and session — the whole record, laid out calm and exact enough to read every morning.
The AI coach analyses your own trade history and surfaces the patterns you can’t see in a spreadsheet — then writes them back in plain English, with the three fixes that matter most this week.
Tag your emotional state, map mood against your equity curve, and let the Tiltmeter catch you before a bad day becomes a bad week. Set hard risk rules and we’ll flag the moment you break them.
Capture the trade and the rationale in seconds from your phone — while the read is still fresh. Everything syncs back to the ledger instantly.
Turn a clean trade into a shareable card with one tap — show your edge in R and %, keep your dollars private. Climb privacy-controlled leaderboards and follow traders who keep score.
