Find the leak in your trading.
Mettle is the trading journal that grades your execution and shows what your mistakes cost you. Try it on five demo trades below, no signup, and Cass names the habit that's costing you.
You don't have a strategy problem.
You have a feedback loop
problem.
You log trades. Mettle compares each one to the play you wrote down and shows you, week by week, what your execution cost in dollars. Most journals stop at logging. This one runs the whole loop.
Built by ddk, a pro esports caster you've seen on ELEAGUE, FACEIT, PGL, StarLadder, and BLAST Majors, who put the review discipline of pro esports to work on his own trading.
The brokers we auto-sync. Every fill pulled in automatically. Trade somewhere else? CSV import covers any broker.
The loop, every trading day.
The Journal runs the whole loop with you, from your first play to your weekly review.
Build
Define the plays you trade. Entry, exit, confluence. Written down where you can grade against them.
Trade
Log every trade against the play you meant to run. Intent on the record, before the outcome is known.
Measure
Every trade scored on entry, stop, exit, and sizing. The behavior behind it tagged.
Grow
Patterns surface. Your leaks show up in dollars. The plan-to-fills gap narrows. Cass flags what to fix.
Here's what's running today.
The dashboard
What you see when you sign in. Your readiness gauge, your BRI score, candles from your last session, and the week's running P&L.
Every trade gets a page
The candle chart with your entries and exits marked, the plan you committed to, the behavioral tags, and your notes.
Cass coaches off your journal
Concept teaching grounded in your trades. Cass draws candlestick patterns, pulls in web research, and proposes rules straight from the conversation.

Questions traders ask.
How is this different from TradeZella or TraderSync?
Most journals capture data and stop. Mettle is built around the loop. You log trades against the plays you wrote down, score the execution, and tag the behavior. The record turns into a behavioral score that moves as you close leaks. The Trader and Master tiers come next to automate more of it.
Who is Cass?
Cass is the AI inside Mettle. Walks you through onboarding the first time you log in. Reviews each trade you ask about. Weekly review of your trading. When you upgrade to Trader, Cass coaches you live with memory of every play and trade. Built to act like a senior trader who agreed to mentor you, not a chatbot.
How does the free preview work?
Sign up free with no card and get full Apprentice access for 14 days. Around your third reviewed session — the point where the Journal has shown you a real pattern — we'll invite you to lock in the founding rate. No card up front, no charge on a date you forgot about.
What does 'early access' mean and why only 50 seats?
The Journal core is mature and you can use it from day one. The Trader and Master tiers around it are still being built. Opening to 50 founding members lets us fix rough edges fast with a small group and ship new features straight to them as we build. The cap can be raised later. It won't be lowered. The founding rate stays meaningful.
What is the founding rate?
$9.99/mo, locked for as long as you stay continuously subscribed. Once the 50 founding seats fill, the Journal is $19.99/mo. Founding members keep $9.99, and they lock a reduced founding rate on the Trader and Master tiers too when those launch.
Does Cass actually know trading?
Cass reads your trades, your plays, and your tags before responding. Every reply references your own data, not generic AI advice. There's a fair-use cap each month so the price stays honest.
What brokers do you support?
Two ways in. Live auto-sync pulls every fill straight from your broker. We support Webull, Robinhood, Schwab, Fidelity, Interactive Brokers, Tastytrade, TradeStation, Tradovate, thinkorswim, and NinjaTrader, with more landing as we test them. Trade somewhere we don't auto-sync yet? CSV import works for any broker.
Is there a community?
Yes. Founding members get a seat in the Mettle Discord. It's the fastest line to the founder and where the roadmap gets shaped.
Do I own my data?
Always. Export to CSV anytime, cancel anytime with your data intact. If your subscription lapses you keep read-only access to everything you logged.
What if I'm not profitable yet?
That's exactly who this is for. The Journal shows where you're leaking in dollars. Fix the behavior instead of guessing.
Run the loop.
Every trading day.
Every session without a structured review is data you can't get back.
