Brain
The brain is the agent’s model plus its trader personality — raw intelligence and how it carries itself into a trade. It is written into the prompt the model reasons with. It never edits your strategy modules or protocol; those stay on the strategy.
Defaults on a blank draft come from platform config. Today that usually means Claude Haiku 4.5 and Moderate · Realist · Measured.
Quick map
| Piece | What it does |
|---|---|
| Model | Which approved LLM decides on each signal |
| Risk | How hard it is willing to stake |
| Outlook | Bias when signals are ambiguous |
| Conviction | How much confirmation it needs before committing |
Model
Only approved models appear in the picker (grouped by provider). Each row shows three meters from Artificial Analysis where published — scores are 1–5, or blank when a metric is not available:
| Meter | Measures | Higher means | Lower means |
|---|---|---|---|
| Intelligence | Reasoning depth on conflicting evidence | Catches subtle, multi-signal setups; fewer false entries on borderline trades | Decides quickly on clear patterns; can miss nuance when signals disagree |
| Cost | Spend from your daily LLM credit pool per decision | Premium pricing — fewer evaluations per day on the same credits | Cheap to run — more headroom to evaluate signals |
| Speed | How fast a decision returns once a signal fires | Snappy — useful when entry timing is tight | Slower — fine for slower cadences where seconds matter less |
Pick the mix that fits the job, not the biggest name:
- Fast / frequent — lower Cost, higher Speed; Intelligence can stay modest.
- Hourly / swing — balanced across the three.
- High-conviction / messy signals — raise Intelligence; Cost and Speed matter less.
If a previously saved model is no longer approved, the UI shows Model unavailable — pick another before you can save.
Reading the live catalog
The picker is the source of truth (models change). Snapshot of how to read a few common picks:
| Model | Typical read of the meters |
|---|---|
| Claude Haiku 4.5 (catalog default) | Modest Intelligence, mid Cost, strong Speed — solid all-rounder for frequent evaluation |
| Claude Opus / GPT flagship tiers | Higher Intelligence and Cost — fewer, deeper reads |
| Flash / Nano / low-Cost rows | Cheap evaluation budget — more signals per credit day |
| Pinned / provider-featured rows | Same meters; still choose by Intelligence · Cost · Speed, not the pin |
Meters are advisory for selection. They do not change your Risk management rails.
Personality (trader soul)
Three axes. Each choice has a short label in the UI and a matching instruction the agent is told to follow when it reasons.
Risk — how big you stake
Appetite for position size and variance.
| Choice | In plain words | What the agent is told |
|---|---|---|
| Conservative | Modest commitment; fewer, higher-confidence bets; steadier outcomes | Stake cautiously — keep commitment modest and prefer fewer, higher-confidence bets. Accept lower variance for steadier outcomes. |
| Moderate (common default) | Commit when a setup earns it; don’t overextend on one thesis | Stake with balance — commit meaningfully when a setup earns it, but never overextend on a single thesis. Tolerate moderate variance for a solid result. |
| Aggressive | Concentrate on strongest reads; chase larger moves | Stake boldly — concentrate behind your strongest reads and chase the larger move. Accept higher variance and drawdown for an outsized result. |
Risk personality is not Max Exposure or Small/Medium/Large %. Those are hard rails on the Risk Management step. Personality biases how the model uses the size presets it is allowed.
Outlook — which way you lean
How ambiguous signals are read, and the confidence baseline.
| Choice | In plain words | What the agent is told |
|---|---|---|
| Optimist | Ambiguity → opportunity; warmer confidence; breakouts get the benefit of the doubt | Read ambiguous signals as opportunity and lean toward upside continuation. Start from a warmer confidence baseline and give breakouts the benefit of the doubt. |
| Realist (common default) | Face value; no directional lean; confidence from evidence only | Read signals at face value with no directional lean, weighing opportunity and trap evenly. Anchor confidence strictly to the evidence in front of you. |
| Pessimist | Ambiguity → trap; guarded confidence; setups must prove themselves | Read ambiguous signals as a trap and stay alert to downside reversals. Start from a guarded confidence baseline and make setups prove themselves first. |
Conviction — how much evidence before committing
| Choice | In plain words | What the agent is told |
|---|---|---|
| Cautious | High bar — several independent signal categories must agree | Raise the evidence bar — require confirmation from several independent signal categories before committing. Prefer setups where multiple categories agree. |
| Measured (common default) | Primary signal + one confirming read from another category | Hold a balanced evidence bar — a primary signal plus one confirming signal from a different category is enough. Weigh confirmation and opportunity evenly. |
| Bold | Lower bar — strong single-category conviction can lead | Lower the evidence bar — act on strong single-category conviction. A powerful momentum signal or clean structure breakout can suffice without full confirmation. |
How Brain pairs with Strategy and Risk
- Strategy decides what the agent sees (modules, rules, timeframe).
- Brain decides how the model interprets that evidence (model + soul instructions).
- Risk management decides whether a sized trade is allowed (exposure, stops, sizing %).
Same playbook + Aggressive · Bold · Optimist will press harder and earlier than Conservative · Cautious · Pessimist — still inside the same capital rails.
Scenario sketches
| Intent | Brain sketch |
|---|---|
| Steady Radar autopilot, limited credits | Haiku or other mid/low Cost · Moderate · Realist · Measured |
| Catch early breakouts, accept noise | Higher Speed or Bold · Optimist · keep Max Exposure tight |
| Only take A+ multi-signal setups | Higher Intelligence · Cautious · Realist or Pessimist |
| Press size when conviction is high | Aggressive personality and review Large % / Max Exposure on Risk Management — personality alone does not raise the rails |
Create vs edit
You set Brain when you commission the agent (Agents overview). You can change model and personality later on the agent console — the same three axes and approved-model list.
