## Description

Evaluate account-level drawdown circuit breaker rules from trader-memory-core state and decide whether new trade risk is allowed today. Uses realized P&L, losing-streak cooldowns, and weekly/monthly drawdown limits without any external API.

# Drawdown Circuit Breaker

## Overview

Evaluate whether the trader should take new trade risk today based on account-level realized P&L and recent terminal trade outcomes. This skill reads trader-memory-core thesis YAML files only. It produces a `circuit_breaker_decision` artifact that complements the market-side `exposure_decision` from exposure-coach.

The circuit breaker is a recommendation and recordkeeping tool. It does not replace human judgment, and it does not enforce broker-side blocks or automated order rejection.

## When to Use

- Before screening or sizing any new swing trade candidate
- After a losing trade or partial trim to check whether a cooldown is active
- During daily planning when trader-memory-core contains recent closed or partially closed positions
- As a workflow gate before swing-opportunity-daily proceeds to candidate generation
- When reviewing whether daily, weekly, or monthly loss limits have been breached

## Prerequisites

- Python 3.9+
- Local trader-memory-core thesis YAML files, usually under `state/theses/`
- Account size in dollars
- No API keys or network access required

## Workflow

### Step 1: Read Trader Memory State

Point the script at the thesis state directory:

```bash
python3 skills/drawdown-circuit-breaker/scripts/check_circuit_breaker.py \
  --state-dir state/theses \
  --account-size 100000 \
  --output-dir reports/
```

The script scans every `th_*.yaml` file and reads realized P&L from each thesis `status_history[]` ledger entry. It does not use `_index.json` for P&L, because the index is a lightweight lookup file and does not contain the required realized-P&L ledger.
