AI COACH

Stop repeating
the same trading
mistakes.

Build plays. Log trades. Get Cass to review. That's the loop — and Cass remembers every trade you've ever run so its feedback compounds over time.

BRI Score 72 +4 this week
3 steps: Build → Trade → Cass review
Cass remembers every trade
BRI scores your behavior, not just P&L

The loop, every trading day.

Mettle runs the full cycle: write your play, log your trade, score your execution, and see where it cost you. Most journals stop at logging. Mettle runs the whole loop.

01

Build

Define the plays you trade. Entry, exit, confluence. Written down where you can grade against it.

02

Trade

Log every fill against the play you meant to run. Intent on the record before the outcome is known.

03

Measure

Every trade scored on entry, stop, exit, and sizing. The behavior behind it tagged and tracked.

04

Grow

Patterns surface. Leaks show up in dollars. Cass flags exactly what to fix next.

Everything runs from your first session.

Trade logging

Every fill, every session. Auto-synced from Webull, Robinhood, Schwab, Fidelity, IBKR, Tastytrade, TradeStation, Tradovate — or CSV from any broker.

BRI score

One number that moves as you close leaks. Behavior, Risk, Income rolled into one discipline metric. Track it week over week.

Playbook

Every play gets a written page. Stack them into a TradingView indicator that pushes alerts back into Mettle. Grade each trade against the play.

Behavioral tags

The why behind each trade. Every session tagged with the behavior that ran it — not just the outcome. Find the pattern you keep repeating.

Broker sync

Every fill pulled in automatically. No manual entry, no copy-paste. Your journal reflects reality, not your memory of it.

Weekly review

Cass picks a lesson trade from your week and grades your execution across entry, stop, exit, and rule compliance. AI writes the analysis. The data is yours.

Cass remembers you.

Cass isn't a stateless chatbot. Before any reply, it loads your last two weeks of trades, your mapped plays, and your earlier conversations. That context is the whole moat.

Conversations stay in your history. Pick up a thread from last week exactly where you left off.

Every reply references your trades, not generic AI advice. Cass reads your journal before answering.

When a discussion lands on a real rule, Cass proposes adding it to your playbook. One click to apply.

Cass
How do I stop blowing up my account after a loss?
Looking at your last 12 trades... your avg loss after a red day is 2.3x your normal size. You are revenge-trading chop. The pattern started 3 weeks ago when you took a bad SWING trade after hours.
That's exactly it. How do I fix it?
Proposed rule: No new positions for 30 minutes after closing a losing trade. Want me to add it to your playbook?

In esports, you review your VODs, tag mistakes, drill specific weaknesses, and measure improvement week over week. In retail trading, almost nobody does any of it.

Mettle is the feedback loop I wanted for my own trading. Built from 20 years of competitive performance work — structured review, behavioral tagging, measurable improvement. The same loop that works in esports works in trading. The only difference is most traders never had access to it.
