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 log trades. Mettle compares each one to the plan you wrote down and tells you by Sunday what your execution cost in dollars. Most journals stop at logging. This one runs the whole loop.
Free to start, no card. Full access for 14 days. We only ask for a card once you've reviewed three sessions, and the founding rate locks when you subscribe.
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 Journal runs this loop by hand. The Trader and Master tiers come next to automate the Build and deepen the Grow.
Define the plays you trade. Entry, exit, confluence. Written down where you can grade against them.
Log every trade against the play you meant to run. Intent on the record, before the outcome is known.
Every trade scored on entry, stop, exit, and sizing. The behavior behind it tagged.
Patterns surface. Your leaks show up in dollars. The plan-to-fills gap narrows. Cass flags what to fix.
Captured from the live app on prod. The data is what founding members are looking at right now.

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.

The candle chart with your entries and exits marked, the plan you committed to, the behavioral tags, and your notes.

Concept teaching grounded in your trades. Cass draws candlestick patterns, pulls in web research, and proposes rules straight from the conversation.

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.
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.
Sign up free with no card and get full Apprentice access. We only ask for a card once you've reviewed three trading sessions, the point where the Journal has shown you a real pattern. You've got 14 days to get there. No card up front, no charge on a date you forgot about.
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.
$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.
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.
Two ways in. Live auto-sync pulls every fill straight from your broker. We support Webull, Robinhood, Schwab, Fidelity, Interactive Brokers, Tastytrade, TradeStation, and Tradovate, with more landing as we test them. Trade somewhere we don't auto-sync yet? CSV import works for any broker.
Yes. Founding members get a seat in the Mettle Discord. It's the fastest line to the founder and where the roadmap gets shaped.
Always. Export to CSV anytime, cancel anytime with your data intact. If your subscription lapses you keep read-only access to everything you logged.
That's exactly who this is for. The Journal shows where you're leaking in dollars. Fix the behavior instead of guessing.
Every session without a structured review is data you can't get back. Free to start, no card, founding rate locked when you subscribe.
Start free, no cardFree to start, no card. We only ask for a card once you've reviewed three sessions. Your data stays yours.
