Talk to the market — with your full context loaded.

Carrac [C⁴] connects Claude, Gemini, and Cursor via MCP. 33 tools stream your live market data, derivatives regime, positions, plays, and journal into the chat — the model reasons with your actual book, not a blank screen.

Intelligence · Derivatives Regime

Stop trading setups that fail in the wrong regime.

Every morning, Carrac fingerprints the market into 1 of 12 deterministic regimes using basis, skew, IV term structure, DVOL, GEX, and funding. No ML black boxes — every classification is auditable, and every regime ships with a playbook.

Workflow · Journal

Your journal remembers what you won’t.

Every trade auto-captures the regime, funding, VIX, and scanner verdict at the moment you took it. Then Carrac surfaces the patterns you’d rather ignore — like “you lose 34% of trades in Melt-Up, always from early entries.”

Intelligence · Formula Engine

Write it once. Run it everywhere.

One expression — across price, macro, and derivatives — reused across scanner criteria, alerts, backtests, play conditions, and chart overlays. 60+ indicators and 6 stateful primitives let you express setups most retail platforms can’t.

Intelligence · Morning Report

The 4:45 AM brief your book actually needs.

A narrative, not bullet points. What regime we’re in, where positioning is leaning, what matters today, and what invalidates your current view. Delivered to web, ntfy, and Telegram. Premium gets it personalized to your assets and scenarios.

Not for traders who want signals. For traders who already build theses and want an AI that reasons with them.

What Claude actually sees

Every answer includes your positions, your theses, and your past behavior — not just the chart.

Five layers of context stream into the model the moment you ask. No copy-paste. No screenshots. No translation layer.

01
Market state

Not just price

  • Current regime (1 of 12) with confidence + secondary regime
  • Basis (APR), funding, 25Δ skew, IV term structure
  • GEX positioning + flip level
  • IV vs RV premium — are options overpriced or underpriced?
“Is this a trend continuation or pre-event tension?”
A regime classification with the exact variables driving it — and what would invalidate it.
02
Your book

Actual exposure, not guesses

  • Spot + perps (long and short) in one view
  • P&L, R-multiple, risk flags
  • Distance from entry to invalidation
  • Scanner verdict on each open position
“Where am I leaning too hard?”
Exposure vs regime and derivatives positioning — e.g. “3 longs, all in negative-skew regime with rising funding.”
03
Your theses

Not disconnected trades

  • Thesis, direction, assets
  • Conditions engine — how many are actually met right now
  • Invalidation criteria (set at creation, not hindsight)
“Which of my plays are actually valid right now?”
“2 of 3 plays aligned. Your ETH long is fighting rising skew — 1 condition reversed since entry.”
04
Your behavior

The part most traders ignore

  • Journal entries with entry-time market context
  • Mistake tags: fomo, early_entry, chasing, oversized…
  • Performance by regime, setup type, and asset
“Am I repeating the same mistake again?”
Pattern recognition tied to real trades — e.g. “last 6 losses came from early entries in Vol Compression.”
05
Historical precedent

Not vibes

  • Conditional forward returns
  • Lead-lag relationships (e.g. DXY → BTC)
  • Top-5 historical analogues to current conditions
“When we looked like this before, what happened next?”
A distribution of outcomes — not a single prediction.
You’re not asking an AI for opinions. You’re querying your own system — with the full market and your full history attached.
The rest of the stack

Carrac works without AI too. Here’s what sits under the MCP layer.

Three moats that every serious trader benefits from — with or without a model in the loop.
