Inside the cockpit

Find your edge.
Sharpen it.

Dashboard — the day, distilled

Net P&L, execution quality, edge drivers and your equity curve — one calm screen that carries the whole story.

Accounts — rules, always in sight

Drawdown distance, winning days, payouts and rebill dates per account — before you take the next trade.

Calendar — time, color-graded

Every day graded by outcome, weekly and monthly performance in the margins, journal markers where you reflected.

Analysis — where the answers hide

Slice performance by weekday, session, strategy, emotion or mistake — and find out what actually pays you.

Four disciplines

One journal.
Every way you trade.

Live prop capital

Guarded, every session.

Your funded accounts on one board — with the rules that keep them alive always in sight.

  • Distance to daily and max loss limits, per account
  • Payout history, winning days and consistency tracking
  • Rebill dates, billing state and account health at a glance
Explore Funded

Evaluations & combines

Pass with proof.

Every evaluation tracked from first trade to funded — targets, minimum days and the moment you convert.

  • Profit target and minimum-days progress
  • Pass / fail state with full trade history behind it
  • One step to convert a passed challenge into a funded account
Explore Challenge

Your own capital

Same discipline, your money.

Personal accounts get the same cockpit — daily goals, personal loss limits and streaks that keep you honest.

  • Personal daily loss limits and daily goals
  • Day and trade streaks across your accounts
  • Fully siloed from prop data — clean statistics
Explore Personal

Sessions, not accounts

Rehearse before it counts.

Import FXReplay or CSV sessions, attach a hypothesis, and review backtests with the same analytics as live trading.

  • FXReplay and CSV imports into named sessions
  • Hypothesis notes, session sparklines and win rates
  • Compare strategies before risking a cent
Explore Backtest

The craft

Everything a serious
journal should carry.

A quiet place to think

A rich-text daily journal with autosave, screenshots and per-day stats pinned to every entry. Your calendar remembers which days you reflected.

  • Rich text
  • Autosave
  • Screenshots
  • Day markers

Your history, in minutes

A CSV wizard with broker presets and FXReplay backtest imports. Professional adds one-click sync for MetaTrader 5, ProjectX, Capital.com and OANDA — pulled when you click, never in the background.

  • CSV wizard
  • FXReplay
  • MT5
  • ProjectX
  • Capital.com
  • OANDA

Rules that never sleep

Inactivity alerts before deadlines bite, corrections that keep balances honest, and copy groups for leader–follower accounts.

One file, the whole story

Self-contained HTML performance reports — equity curve, calendar heatmap, breakdowns — that open offline and travel anywhere.

  • Equity curve
  • Heatmap
  • Dark / light

Six tools, always at hand

R:R visualizer, position size calculator, equity simulator, timezone and currency converters, futures contract specs — built in.

Slice by anything

Strategy, session, emotion, mistake, asset, timeframe, direction, tags — flip a filter and every metric recalculates instantly.

Your trades are your story. They belong on your machine, not on someone else's server. Katsumii keeps everything in a local database — offline, private, and entirely yours.

Compatibility

Runs on Windows and macOS.

Everything works identically on both platforms — except MetaTrader 5 sync, which needs Windows.

Runs on

  • Windows 10 or newer
  • Windows 11 recommended
  • macOS 12 Monterey or newer
  • Intel/AMD 64-bit and Apple Silicon

System requirements

  • 8 GB RAM
  • 1 GB free storage
  • 1440 x 900 display or larger
  • Internet connection for product activation, updates, API sync, and integrations

Integration note

MetaTrader 5 sync is currently Windows-only and requires a locally installed, running MT5 terminal. On macOS, Katsumii supports manual imports, analytics, reports, backups, and supported API integrations.

API access

API usage may be paid and depends on your broker. Katsumii works with broker integrations only when you have a matching API key.
